High-capacity embedded in the compound in the development of lithium ion battery

South lithium Fourth (International) Senior Technology Forum today in Shenzhen Convention and Exhibition Center. The General Assembly, "Power 2009 - Power Battery, 3G high-capacity battery, netbook battery" is the theme of hundreds from across the lithium industry experts, corporate executives attended the forum and how to deal with the financial crisis lithium industry and explore new markets, new opportunities, grasp the development trend of the industry and discuss hot.

The following is the macro Sanyo Dr. Nakamura speech text Record:

Moderator: Mr. Xie Xieyang! Have requested the next company over Sanyo, Dr. Nakamura macro.

Nakamura Wang: Thank you very much for inviting me to participate in this forum, I am very honored to be able to participate in the forum. Today I will tell you about what some of our basic research, research on the two materials, the two studies can be at a higher structural stability of the potential to improve the capacity of anode materials. The first is the anode material of lithium-rich, and the second is obtained through the exchange of sodium layer of the anode material states. (PPT)

First, let me first briefly introduce the background of our study, lithium batteries on the market is basically to do with the lithium cobalt oxide anodes with graphite cathode, which is the question of how to to improve the current system of lithium cobalt oxide The capacity of lithium batteries, or even more than the current capacity. We all know, the capacity of graphite which is close to his capacity, and one way is to find a new cathode materials can give us a higher capacity, such as aluminum cathode. Another is to increase the capacity of the anode, and today I want from the second level is to increase the capacity of anode materials in terms of this problem.

PPT summed up what this energy density, energy density is calculated as the average potential of the product capacity × × actual density, can be charged to a higher potential, in fact, this method is to increase the number of lithium cobalt oxide and other materials or MCL and the capacity to improve his energy density. From this number which we can see his potential as a charge to a higher one way to increase the density of them.

I share with these data obtained using the three main channels of the test battery electrode experiments obtained, in addition to this experimental film of aluminum air battery, it's normal capacity is 600-800 mAh. I'm with you first to introduce lithium-rich anode material, can use this formula to write about, you can use some transition metal parts, this is a very typical formula, often marked with a ICM material, the characteristics of this material is his capacity is relatively high, the time to over 200 mA per gram, can reduce the amount of cobalt, so you can reduce costs. The lithium-rich material can be said that many researchers have been numerous studies, some people in office, this is a reference to the papers, many of the data from this paper. Wei Boshi in the last race could have also participated in the meeting, but also to speak. This is the characteristics of lithium-rich materials, phone, black is the first cycle, the red is the second cycle, the capacity is relatively large, is 270 mA per gram, the initial charge and discharge efficiency is relatively high, this situation The following is about 83%. Another feature we can see that there are very different, that is, in the first cycle and second cycle of the curve being a great difference. The slide in the literature which explains the possible mechanism of charge and discharge, in terms of this capacity for this material comes from traditional methods of oxidation, the oxidation of this lithium-rich material, 4.4V when the oxygen by oxidation, materials which release oxygen, manganese will be captured. After the first discharge, the capacity to connect through this oxidation reduction reaction, that is, for this transition metal redox reactions, this layered manganese oxide by this structural change, we can see has been such a material.

PV market demand drop

PV market demand drop

Since the 4th quarter of 2008, the drop of solar energy demand, increased pressure on the stock battery manufacturers both sides, because the capital needs of low-priced sales, the market came part of the international contract customers can also change the pickup module approach has signed contracts required suppliers offer, allow suppliers to draw the circle first, some fighting, then select the lowest purchase, solar energy companies, said 1st quarter 2009 if demand remains in the doldrums, I'm afraid to increase the probability of such violations will follow heightening .

Since the 4th quarter of 2008, demand for solar PV market frozen, leaving both sides a rapid increase in solar cell factory inventory levels, to address the problem of funding needs and inventory pressures, grab a single action to kill because of lack of funds and the stock pressure, to the not yet completely subsided.

Since 2008, the contracts signed years, more non-rigid restrictions, including price, delivery quantity, delivery time and so not very hard and fast rules, coupled with the rapid changes in market conditions, supply chain market rapidly from a seller to a buyer Therefore, some international purchases module plant began to change strategy.

These modules one by one supplier factories require the contract offer before a contract supplier to bargain with each other about it, and then select the lowest bid contract supplier of the goods, the contract market but has become the fastest battlefield bargain, the other unsuccessful suppliers stocking according to the contract, but ended up shipping nowhere, but increased the pressure on stocks.

Solar energy companies, said the situation reflects the number of contracts enforceable not been apparent in 2009, although the contract customers are willing to set a significant reduction relative to 2008, but there is still a significant proportion of international companies in order to ensure stable supply, signed a supply contract .

Urban conditions in 2009 but the uncertain spot price of the contract price may still be threatened, especially off-season when the first one end of the quarter end, as expected if the market's reversal, the current prices remain stable longer fear the threat, the same, contract enforcement and binding will be challenged again, the above situation may result from spreading.

Solar cell manufacturers, said the situation in the 4th quarter of 2008, the battery increasingly evident since the start price, but after all still a small number of customers, so, many battery manufacturers shall be set in 2009, the contract will be more to enhance communication between buyers and sellers, period can provide customers a reasonable price and stable material source.

Continental battery manufacturers, including Suntech, Solarfun, China Sunergy, crystal and Australia, Taiwan solar cell makers, including Motech, E-TON, the new sun, Yu Jing, Sun Branch, Wang can wait; both sides offer similar trend, each about 2 to 2.4 watts of dollars, of which the market believes that a single force service providers to the mainland than to Taiwan-based factory fierce.

Battery is the mobile Internet of the "shortcomings"

Battery is the mobile Internet of the "shortcomings"

As of the end of June, 253 million Internet users in China, mobile phone users wireless access to the terminal has reached 7305 million, accounting for Jinsan Cheng. Characteristics of mobile phone users showed younger - 30 years of age accounted for 86%. Experts said that from a technical level, the phone will eventually replace the Internet as the most important communication tool has become pronounced signs (November 24, 2008 "People's Daily").

Experts say signs of mobile phone will eventually replace the Internet has "highlighted" a little exaggerated, not to mention mobile Internet "short board" battery problem is not fundamentally resolved.

Currently, the mobile phone to replace the Internet as the most important tool is also very slim prospect. Mobile phone than a computer keyboard to input Chinese characters to input Chinese characters for its slow, almost can not compare. Mobile phone screen is too small to see if the image is a mean, wide-screen with the computer effects are not in the same language. Even if the solution of the mobile Internet is slow and the cost of your problems, mobile phone, compared with the computer, but also a "dwarf."

"Three as" mobile phone users this figure, I am afraid of water too much, because the definition of mobile phone users are too "loose." What is mobile phone users? Do all cell phones are occasional short-term mobile phone users who get online it? If this is the standard, then I am afraid that mobile phone users to account for 80% of the total number of mobile phone users over.

Mobile Internet users with computer users should at least consistent with the standards, such as regular Internet users with a longer time and as a general understanding of information channels. Now, with the mobile Internet, but the road to keep abreast of important information about their own interest only, online time is very short stay, and a return home, conditional on the computer to the Internet.

Currently, the mobile Internet of the "short board" is the cell phone battery life too short. A battery, for routine calls, generally only use two or three days; long talk, I am afraid that one day is not enough. There are a few so-called high-capacity battery, although the manufacturers marked exaggeration, but the continued use of the time more than where to go. If, as the computer a few hours as a continuous Internet access, cell phone batteries do that?

As the 3G era, the wireless transmission technology produces a qualitative leap in mobile phone technology will be closer to the same level of the computer. However, if the phone battery does not solve the "short board" problem, then the most advanced mobile phone technology will become a "decoration." Finally, the mobile phone battery mobile phone with the times to become the biggest "bottleneck."

In fact, many new tricks on the current mobile phone for most users are "display"; users to spend higher price mobile phone, a user of funds and a serious waste of social resources. Thus, the present should spend more time to spend more funding for research on mobile phone battery capacity increases, increasing phone battery life and safety issues, so as to truly gradual reduction of the gap between mobile phone with the computer.

Four doors for the roughneck A

Four doors for the roughneck A

The 65th Birthday, he has long since behind him – but no trace of pension. On the contrary: for the first time in its history, there is the classic Jeep as a 4-door and otherwise thoroughly revised. apple battery



For the soft-family swing that makes him still a long way: A Jeep is a Jeep, a Jeep – even with four doors, ESP and Isofix. To stroll the others are there. Those who are called to be confused with SUVs and SUVs only. The also have all-wheel drive, but never have to face steeper obstacles than the curb. drive Jeep Wrangler Unlimited is working – the way is the goal. Even now. apple powerbook g4 battery

Those who just want comfortable and casual slip from A to B, who is in a C-class to almost the same price in safe hands better. Despite everything, brings more comfort and the latest Jeep with a bunch of characteristics that would be enough to slating every other car – the jeep but just make up the lovable character.

The angular appearance, for example, when it pays not only to ask for the drag coefficient. And the recalls in every corner of the history of off-roader. In the German version, for example, the windshield can be folded away long gone forward – but there are still on the hood of the rubber plug on the once rested the frame. The bonnet itself is not open as usual on a lever in the footwell but with two locking bones left and right. lenovo thinkpad x200 battery

The doors are still turning in solid, hinges bolted to the body and are held by adjustable straps. Who opens the door does well to keep it firmly: There is no snapping. On the slope is one, depending on the roll again towards the door slams or far on. On boarding you have to heave up into the seat, dropping out is more like a slide down. The Jeep even once wide stiles and narrow windows block the view diagonally to the rear. At least the front can be due to the fracture edge square estimate good when everything ends. The side mirrors are pressed through the open window to the ancient custom of fathers in the right hand corner – which requires, above all, on the passenger side, long arms and a lot Rutscherei. At night, lights inside only a dim light in the roll bar on the scene of more than bad law.

Vier Türen für das Raubein B

Vier Türen für das Raubein B

Der Wrangler ist auch in der Kingsize-Version ein Cabrio. Serienmäßig kommt er in der 53 Zentimeter längeren viersitzigen Version mit einem manuell klappbaren Softtop daher. Ratsamer ist in mitteleuropäischen Breiten allerdings das 3200 Euro teure Hardtop-Paket. Wer im Sommer wieder offen fahren will, muss sich auf Fummelei und Schrauberei gefasst machen. Schon die vorderen zwei Dachhälften lassen sich nur über fünf Klemmen und zwei - allerdings griffige - Schrauben demontieren. Die sperrigen Dachteile stehen dann in der Garage - und fehlen vor Ort, wenn der Regen kommt. Oder sie ruhen sperrig im Kofferraum. Der ist mit bis zu 2320 Liter (bei umgelegter Rückbank) immerhin üppig bemessen und lässt sich gut beladen. Die untere Hälfte der Hecktür mit dem Reserverad schwenkt nach rechts weg, das Rückfenster dann nach oben. pcga-bp2e battery

Der 2,8-Liter Diesel unter der Fronthaube passt zum Charakter. Eine halbe Drehung am Zündschlüssel - und man fühlt sich fast wie auf einem Traktor. Der Diesel nagelt knorrig, laut und ungehobelt vor sich hin und gibt sich auch beim Fahren keine Mühe, sein Arbeitsprinzip zu verbergen. So nimmt man nur am Rande den Fahrtwind wahr, der ab Tempo 120 zu pfeifen beginnt. Die 130 kW/177 PS und das Drehmoment von 410 Nm des bulligen CRD-Motors kommen kraftvoll auf die Straße und reichen aus, um den Zweitonner in gut elf Sekunden auf Tempo 100 zu bringen. Bei 180 km/h ist Schluss. Und das reicht auch. Denn so präzise er sich im Gelände auf den Zentimeter steuern lässt: Autobahn-Tempo macht ihn eher nervös - man muss ständig an der Lenkung nacharbeiten. sony battery

Die Schaltung erinnert an den alten VW-Bus: Der Schalthebel ist ebenso lang wie die Schaltwege - und hakeln gehört beim Jeep zum Handwerk. Immerhin zeigt sich die Federung trotz Starrachsen vorne und hinten als ebenso überraschend komfortabel wie die Abstimmung des Fahrwerkes insgesamt. In dem Wrangler sorgt zudem Elektronik inklusive ESP für ein sicheres Fahrverhalten in allen Straßenlagen. Und wer nicht gerade mit Bleifuß unterwegs ist, kommt mit knapp unter 11 Litern Diesel auf 100 km auch noch relativ ordentlich davon für einen echten Offroader.

Klingt alles furchtbar nach Verriss? Eigentlich mehr nach einem liebenswerten Auto mit Charakter und Geschichte. Denn all das gehört mit zum ganz speziellen Charme des Jeep Wrangler Unlimited. Und richtig gute Eigenschaften gibt es ja auch noch reichlich. Seine in allen Teilen schier sinnlich wahrnehmbare Robustheit etwa. Das üppige Platzangebot in dem 4,75 Meter langen und 1,87 Meter breiten grünen Riesen - vorne und hinten. lenovo thinkpad x61 tablet battery

Die ungebremst positive Ausstrahlung, die so vielen glattgelutschten Autos heute fehlt. Unschlagbar ist der Wrangler auch in der Langversion im Gelände. Starrachsen, zuschaltbarer Allradantrieb, Geländeuntersetzung - der Wrangler schafft die schwierigsten und extremsten Offroad-Trails. Geröll, Furten, Felsen, Hänge, Sanddünen - alles dank der aus 65 Jahren stammenden Erfahrung kein Problem. Da klingt der Basispreis von 29.990 Euro doch fast schon günstig.

Den 65. Geburtstag hat er längst hinter sich - doch von Rente keine Spur. Im Gegenteil: Zum ersten Mal in seiner Geschichte gibt es den klassischen Jeep als 4-Türer und auch sonst gründlich überarbeitet. pcga-bp1n battery



Zur weichgespülten Familienschaukel macht ihn das noch lange nicht: Ein Jeep ist ein Jeep, ist ein Jeep - auch mit vier Türen, ESP und Isofix. Zum Flanieren sind die anderen da. Die, die SUV heißen und mit Geländewagen nur verwechselt werden. Die auch Allradantrieb haben, aber nie steilere Hindernisse bewältigen müssen als die Bordsteinkante. Jeep Wrangler Unlimited fahren ist Arbeit - der Weg ist das Ziel. Immer noch.

Wer nur bequem und lässig von A nach B gleiten will, der ist in einer C-Klasse zum fast gleichen Preis sicher besser aufgehoben. Trotz allem Plus an Komfort bringt auch der aktuelle Jeep reihenweise Eigenarten mit, die jedem anderen Auto zum Verriss reichen würden - beim Jeep aber gerade den liebenswerten Charakter ausmachen. pcga-bp2r battery

Die kantige Optik zum Beispiel, bei der es sich gar nicht erst lohnt, nach dem cw-Wert zu fragen. Und die in jeder Ecke an die Geschichte des Offroaders erinnert. In der Deutschen Version zum Beispiel lässt sich die Frontscheibe schon lange nicht mehr nach vorne wegklappen - dennoch gibt es auf der Motorhaube nach wie vor den Gummipfropfen, auf dem einst der Rahmen auflag. Die Motorhaube selbst wird wie gehabt nicht über einen Hebel im Fußraum geöffnet sondern mit zwei Verschlußknochen links und rechts.

Die Türen drehen sich immer noch in robusten, auf die Karosserie geschraubten Scharnieren und werden von einstellbaren Bändern gehalten. Wer die Tür öffnet tut gut daran, sie fest zu halten: Einrastpunkte gibt es nicht. Am Hang kommt einem je nach Seitenneigung die Tür gleich wieder entgegen oder knallt weit auf. Zum Einsteigen muss man sich in den Sitz hoch hieven, das Aussteigen gleicht mehr einem herunter rutschen. Im Jeep selbst versperren erst einmal breite Holme und schmale Fenster die Sicht schräg nach hinten. Wenigstens vorne lässt sich dank der eckigen Bruchkante gut abschätzen, wo alles endet. Die Seitenspiegel werden durch das offene Fenster nach alter Väter Sitte von Hand in die richtigen Winkel gedrückt - was vor allem auf der Beifahrerseite lange Arme und viel Rutscherei erfordert. Nachts leuchtet innen nur eine Funzel im Überrollbügel die Sitzlandschaft mehr schlecht als recht aus. lenovo thinkpad x61s battery

No place for the Blue Revolution

No place for the Blue Revolution

A victory is different: One year after the Blu-ray could prevail as the sole successor to DVD, the sales figures of speech are hardly worth it. The DVD is just too good?

A year ago it was the great attraction of the Consumer Electronics Show (CES) in Las Vegas: The Blu-ray Disc (BD) had in the race for the inheritance of the DVD player's opponents HD DVDEin competition format for a disc with lots of storage space (20 to 25 gigabytes) for film and data, which must be fought in the battle for market shares of the BluRay. cut out after a long bitter fight. Thereafter, the breakthrough of the film disc no longer stand in the way.

At this year's CES, the Blu-ray disc is indeed celebrated everywhere, the expected success is yet coming. The reasons are many: If you want to enjoy the razor-sharp image and superior sound really needs a very large flat screen TV, a new player and an expensive home theater system.

Even the currently most commonly purchased flat-panel televisions with screen sizes of 32 and 37 inches (82 and 94 cm respectively) are really too small for the difference between Blu-ray and DVD really impressive bring over the old. Of course, the superior picture quality of Blu-ray visible even with these devices - a revival experience but it is only from 42 inches upwards. For where the DVD has limitations, catches the Blu-ray in earnest. The same goes for the sound: But who can name even a 7.1 surround system its own?

The supporters - equipment manufacturers, film industry and the major Hollywood studios to see - is still on track. were in the U.S. alone since the introduction of the new storage medium in June 2006, 10.7 million players were sold, "said Andy Parsons, president of the Association lobby Blu-ray Disc Association (BDA). Thus the format of a more successful start than at that time I have put down the DVD sold in the same period of three years only 5.4 million times. Especially in recent years, sales of players have put on three-fold.

Nevertheless, the hope of media industry languishes even three years after starting at around a spread of less than eight percent. In order not to endanger the hype surrounding the technology, the Blu-ray group with sales of publications is quite cautious. An exception has one made for the new Batman movie The Dark Knight, which broke in Germany on Blu-ray all previous records. In the first ten days of selling 64 000 copies were sold. By comparison, on DVD, it was 540,000. Nevertheless, The Dark Knight is a milestone: the world now are more than a million Blu-ray have gone over the counter.

But now also threatens the economic crisis. The question for the all-important U.S. market quite clear: Who needs a Blu-ray player, home theater system and a flat screen TV when he has no roof over their heads? As bad as it seems not to be ultimately, it is believed Paul Erickson from market research firm DisplaySearch. Even though he has corrected the face of the global economic slowdown its expectations downward, but it now expects a steady growth.

Is it possible to identify the demand and home theater systems or at best as there is cool, ice age in the PC sector. At least in the market for Blu-ray drives for PCs and laptops is to develop "rather disappointing, Thomas Nedder, Managing Director of Sony Optiarc Europe," confesses Three years ago we had very different growth rates forecast. "Compared to the DVD drives did the percentage of Blu-ray drives for computers located less than one percent in 2008.

Again, there are several reasons. Formally, 25 gigabytes of disk space for single layer Blu-ray and 50GB dual-layer discs for a strong selling point. But Blu-ray has made powerful enemies: Microsoft was one of the supporters of the now settled Blu-ray competitor format HD DVD. And even supporters like Apple would rather wait on for now.

A positive finding is that the prices for Blu-ray players and movies slow to come in affordable ranges. Now and then some current movies are for getting around the 20. Among the featured just at the CES New developments are also players for under 200.

However, Sony will lose the developer Nedder not to obscure the reality. The time of blind euphoria seems to be over, the expert believes that the changing of the DVD will last quite a few years. And even then there may be many years of coexistence. If the Blu-ray by then not the same outdated: Some observers have been the swan song for the new medium intoned, as physical disk with the spread superfluous faster Internet connections and services such as "video on demand" (Video on Demand) will could.

Richard Doherty of market research, however, for holding the Envisioneering ruled: "It is no country in the world equipped with sufficiently fast broadband, so online download services could close in on the benefits of physical media."
