What is all-weather lithium battery

A to minus 40 ℃, 60 ℃ above freezing temperature stability of the whole climate lithium battery after researchers developed by xinjiang, the technology is expected to solve the lithium battery energy storage generally encountered low-temperature cannot charge problem, especially for winter cold northern areas like xinjiang, "the whole climate lithium battery" will provide strong technical support for new energy vehicles development. In the urumqi competition of "maker China" xinjiang innovation and entrepreneurship competition concluded on August 29, "all-climate lithium battery" stood out from many excellent projects and won the first prize of urumqi competition maker group.

Developed "the whole climate lithium battery technology is an enterprise established in June this year in xinjiang, xinjiang in new electric energy technology co., LTD., the core technology development, led by Dr Xinjiang institute of Chinese academy of sciences wang lei, has completed a variety of high and low temperature under the condition of product testing, is about to enter commercial product production phase.

Coating online learned that the lithium battery which is an electric car widely used kind of electrochemical energy storage and power plant, compared to other battery has the advantages of high energy density, long cycle life, but it has poor low temperature performance, electric range in cold weather about 40-50% lower, under zero cannot charge, to make electric cars "greenhouse flowers". A variety of technologies have been developed by industry and academia to solve the low-temperature problem of lithium batteries, but existing solutions are often complex, costly, or at room and high temperatures where performance is compromised. Therefore, the development of a low-cost, all-climate and high-efficiency lithium ion battery plays an important role in the development of the electric vehicle industry.

To 40 ℃, 60 ℃ degrees centigrade below zero stable work of "the whole climate lithium battery" recently by researchers developed in xinjiang, the technology is expected to solve the lithium battery energy storage generally encountered low-temperature cannot charge problem, especially for winter cold northern regions like xinjiang is of great significance.

In the urumqi competition of "maker China" xinjiang innovation and entrepreneurship competition concluded on August 29, "all-climate lithium battery" stood out from many excellent projects and won the first prize of urumqi competition maker group.

The company that developed this technology is a local enterprise -- xinjiang CNP new power new energy technology co., LTD., which was established in June this year. The core technology is developed by Dr. Wang lei of xinjiang institute of physics and chemistry, Chinese academy of sciences.

The reporter understands, lithium battery is a kind of electrochemical that at present electric car USES commonly store energy and power device, compare with other battery, have the advantage such as high energy density, cycle life is long. But its low temperature performance is extremely poor, electric vehicles in cold weather driving range reduced by 40% to 50%, zero below the ability to charge, making electric cars become "greenhouse flowers".

A variety of technologies have been developed by industry and academia to solve the low-temperature problem of lithium batteries, but existing solutions are often complex, costly, or at room and high temperatures where performance is compromised. Therefore, the development of a low-cost, all-climate and high-efficiency lithium ion battery plays an important role in the development of the electric vehicle industry.

"Although the company has not been established for a long time, it has been focusing on the development of high-temperature and low-temperature lithium ion battery and energy storage system and the research and development of solutions. By providing positive and negative materials of high-temperature and low-temperature lithium ion battery, it can provide high-temperature and low-temperature environment solutions for electric vehicles, drones, robots and other enterprises. Huang chao, deputy general manager of the company, said "all-weather lithium battery" related products are widely used in energy, information, transportation,special,special and other industries, with broad market prospects.

Securities co., LTD., xinjiang urumqi division judges, large branch Dr. FuMing thinks, at present the country are developing new energy vehicles, and lithium ion battery energy storage technology, there are also many strong domestic enterprises in the lithium battery, xinjiang in the new electricity of new energy technology co., LTD. "the whole climate lithium battery" solitary characteristics in low temperature applications, with intellectual property rights, is located in the forefront in the industry. The technology has a wide application prospect in xinjiang, northeast China and even central Asia and Russia. Therefore, the judges have a high opinion of the project and hope to achieve good results in the autonomous region's innovation and entrepreneurship competition held in September.

Reporters learned that the second "maker China" xinjiang innovation and entrepreneurship competition finals will be held on September 19 this year. A total of 12 enterprises and makers won the first, second and third prizes in the urumqi regional competition competition, which ended on August 29. Together with the top 9 enterprises, they entered the final competition of xinjiang. The projects cover the primary, secondary and tertiary industries and e-commerce service fields. The projects in the competition include not only self-developed and highly promoted new technologies, but also new concepts that break through the tradition and marketing.

The lithium battery

Lithium battery is a kind of battery made of lithium metal or lithium alloy as negative electrode material, using non-aqueous electrolyte solution. With the development of science and technology, lithium battery has become the mainstream.

Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable.

The fifth generation of rechargeable lithium metal battery was born in 1996. Its safety, specific capacity, self-discharge rate and performance/price ratio are all better than lithium ion battery. Because of its own high technology requirements, only a few countries now produce such lithium-ion batteries.
