New type of polymer lithium-ion battery successfully developed

New type of polymer lithium-ion battery successfully developed



With independent intellectual property rights of a new type of polymer lithium-ion battery R & D success of a few days ago and will soon be put into the production process of industrialization. This unique battery technology is from 4 years ago returning from overseas, led by its researchers Following the liquid plastic film lithium-ion power toshiba batteries made after the outcome of an important. At present, the polymer lithium-ion battery production lines are under construction.



It is understood that the liquid lithium-ion battery is the most high-tech research in recent years one of the important results, representing the current development of the chemical power of the most advanced level. As a result of such batteries with high specific energy and recycling, the good life, such as a significant advantage, now widely used in mobile communications, cameras, laptops and other electronic devices, and is gradually moving towards electric bicycles, electric vehicles and other areas to expand the scope of application. It is estimated that the global lithium-ion battery demand has reached 1.3 billion, and with the applications and the ever-expanding year by year.



In liquid lithium-ion battery at the same time the successful commercialization of polymer lithium-ion battery (PLIB) research has been particular concern to them. As a new generation of lithium-ion battery system, PLIB not only with liquid lithium-ion battery all the technical advantages, but also has a higher specific energy and better safety performance. In addition, PLIB is recognized as the most development potential and future application of the battery market products. It is predicted that in the next few years, PLIB will replace the liquid lithium-ion batteries for nearly 50% market share, there are broad prospects for the development of Japan and many other major battery makers focus on R & D investment and the direction of.



The past, both at home and abroad polymer lithium-ion battery manufacturers use the United States Bell Laboratories Bellcore process. However, due to the cumbersome process of the method, low efficiency, investment in equipment and the shortcomings of higher cost of production, serious constraints of polymer lithium-ion battery development and industrialization. Domestic and foreign markets in recent years in the so-called polymer lithium-ion battery products, but in fact is a flexible liquid batteries, there are still a large number of internal dynamic electrolyte flow, do not have the characteristics of polymer electrolyte, in the security risk there. With lithium-ion battery in the communications and IT industry's rapid surge in usage, the battery safety performance is increasingly prominent, not only the requirements of lithium-ion battery has excellent electrical properties, also called for greater security.



CITIC Beijing UNITA solid profits and new material technology, Beijing Institute of New Energy Materials and Technology Laboratory, through years of research, in a large number of laboratory work on the basis of a number of key materials through an integrated technology, the first synthesis of a unique structure microporous polymer composite membrane, and then use a unique production process of polymer batteries developed a polymer lithium-ion battery. The battery has a very excellent low-temperature discharge performance and cycle performance (over 500). With the same battery capacity compared to liquid packaging, such polymer lithium-ion rechargeable battery and acupuncture in the past, such as safety testing, in particular, a unique performance advantages. Importantly, by researchers and development of new polymer lithium-ion battery production technology, also has a small investment in equipment and production technology is simple and so on. The results with independent intellectual property rights, there is no doubt China will enhance battery manufacturing sector in the international competitiveness and promote domestic polymer lithium-ion toshiba satellite a75 battery, toshiba satellite p30 battery, toshiba satellite p35 battery industry and greatly expand the lithium-ion battery applications.



Another patent "flowers" off of other family







Maryland Science and Technology staff to develop a scientific and technological achievements, once again bear fruit in the field cassette battery electric bus", shortly before the bus in the east Yangtze River Limited (passenger car factory in Wuhan utility) line. Maryland to create a car company to use the six patented technologies, including four patents, utility models 2, authorizing them to open up a company's patent production. Yesterday, China's first "cassette battery electric bus" back to Lanzhou.



There are more than 30 years of master file Shao said that this new type of electric bus has zero pollution, hydraulic steering, power brakes and other braking characteristics. It is not subject to restrictions on road and rail network, interference, the maximum hourly rate of 80 kilometers.



Created by the Maryland Science and Technology Co., Ltd developed the "cassette battery electric bus", with independent intellectual property rights. The project has entered the Olympic Games in 2008 major projects of Science and Technology Beijing, Beijing Miyun electric vehicles involved in manufacturing engineering. Operation of the national model city for electric vehicles - Shandong Weihai to buy the first two, and then prepared a large number of orders.



The world's first "power refrigeration can" come out of the refrigerator



"Shortage" outbreak, the refrigerator refrigeration still fresh? Case of expensive peak electricity hours, refrigerators can automatically identify and automatically shutdown, the period of low prices can automatically boot refrigeration?



A few days ago, Kelon announced the successful development of the world's first have a "time-sharing of power, power preservation" function of the refrigerator hp pavilion dv8000 battery, 395789-001 battery, hstnn-db20 battery. This refrigerator a sudden power failure for up to 20 hours, the still fresh refrigeration; Moreover, its "time-sharing of power" function, to avoid the high price of electricity in peak hours of refrigeration, auto - to achieve "peak power." It is learned that the "time-sharing of power, power preservation" is the world's first refrigerator technology has been applied to KELON latest "All-Star" series of refrigerators, this refrigerator will be before the end of April across the country listed at the same time.



Strange things: power also refrigerant



Shi KELON what magic, so the refrigerator can continue after the cooling off?



It is understood that the power of the secret is fresh original KELON storage, release cold technology. Power preservation technology is the increase in refrigerator storage compartment separate and unique design of cold-Release Road, installed power of about 1W DC only micro-fans, is equipped with a small sealed maintenance-free battery, when the normal supply of electricity storage device a large number of cold storage, after power-off battery-powered fans, regenerator slowly blowing the cold box to the food, and thus also after the power outage "cooling." It is understood that the ordinary refrigerator after a sudden power failure, the storage room temperature can rise very rapidly; in the no-load conditions, the temperature in the freezer two hours after the -7 ℃ rise to more than two and a half hours in the refrigerator after rose to above 12 ℃, thus the loss of preservation of the capacity of vulnerable food box metamorphism. In recent years, frequent shortage of Jiangsu, Zhejiang and other places, consumers due to power outage caused numerous complaints of food deterioration.



In contrast, preservation of the refrigerator in the power blackout after the storage chamber temperature rise very slowly. In the no-load conditions, 20 hours after the power failure, the freezer temperature can be maintained at below -7 ℃, holding time is a common refrigerator for more than 10 times. If the refrigerator full of food, 15 hours after the power can be maintained at below 12 ℃, holding time of an ordinary refrigerator, about 10 times the capacity of the basic preservation from the impact of power outages.
