Layout development cylindrical lithium battery, linkage Tianyi fast charging multi-choice question submission

In 2020, Tesla released 46800 cylindrical batteries on BATTERY DAY, and in the past two years, major battery manufacturers have developed the layout of large cylindrical batteries. The domestic lithium battery new force linkage Tianyi has also accelerated the layout and promotion of cylindrical products.

On January 10, Blue Whale Finance learned that as a representative of a new generation of energy technology companies, Linkage Tianyi released a 26-46mm series of cylindrical series battery products, different from other manufacturers in the industry, Linkage Tianyi focused on high-end cylindrical batteries and created cylindrical products. Yan Ziyi, Chairman of Linkage Tianyi, said: "Linkage Tianyi is committed to building the world's leading new energy ecological technology with high-performance lithium battery technology, and has become an industry pioneer in the field of power batteries and energy storage batteries. We are firmly optimistic about the long-term development of the new energy automobile industry, our independent brands have grown rapidly in the past few years, showing the innovation ability and pioneering ability of China's industrial manufacturing, reflecting the transformation results from Chinese manufacturing to China's creation, focusing on core technology and product research and development, which is the top priority of Linkage Tianyi. ”

It is reported that Lianyi Tianyi has achieved excellent results in the technology research and development, patent holding, industrial chain layout and global market development of high-performance lithium batteries, and has carried out comprehensive strategic cooperation with many international brands and energy giants to accelerate the globalization of energy technology.

Just recently, Linkage Tianyi released a series of high-performance fast-charging power batteries - SPEED, the energy density of the cell unit reaches 260Wh/kg, the charging 8 minutes can reach 400 km endurance, and the number of fast charging cycles can reach 800 to 1200 times. Speed series of cylindrical / square cells are high nickel chemical system, the cell monomer level has good safety, after the formation of modules / systems can achieve NTP (never thermal runaway), the comprehensive performance indicators are industry-leading. SPEED fast-charging power batteries have received large-scale orders from domestic and international passenger car brands, and will fully achieve mass production in 2022, providing high-performance and high-quality lithium battery products for the global electric vehicle market.

Linkage Tianyi believes that cylindrical batteries can have different designs, for different customers / different use needs, 46mm cylinder is the direction, but not the only answer, so the concept of linkage for cylindrical products is: more than one answer. At the press conference, Dr. Yang Sitao, Vice President and Chief Technology Officer of UMF, presented the latest product development results: the cylindrical lithium-ion battery family, including the previously announced SPEED2 series with a diameter of 26mm, and the newly released SPEED3 series with a diameter of 37mm, and the SPEED4 series with a diameter of 46mm.

Fast charging is a multidisciplinary and multi-professional technology, and its performance requires mechanical, electrical, material, chemical, control and other aspects to work together, is a comprehensive solution. In view of the strict requirements of lithium batteries for force, heat, electricity, manufacturability and other factors in the use of working conditions, Linkage Tianyi released the SPEED3 series with a diameter of 37mm, which can not only avoid the multiple challenges faced by 46mm diameter lithium batteries in terms of manufacturability, heat, force and structural design, but also achieve higher energy density than 26mm lithium batteries, and the comprehensive performance is more balanced and more suitable for high-end passenger cars.

The SPEED4 series is expected to be the next growth point in the industry. 46800 can reach 5 times the capacity of traditional batteries, the corresponding system integration will also be simplified, linkage Tianyi has adopted different structural design and structural functional materials released by Tesla, which can further reduce the weight of the battery, improve thermal conductivity efficiency, and reduce internal resistance. Speed4 series positioning stable system design, the pursuit of lower cost and comprehensive performance, more suitable for ordinary family cars.

In 2020, Tesla released 46800 cylindrical batteries on BATTERY DAY, and in the past two years, major battery manufacturers have developed the layout of large cylindrical batteries. In the vast space of new energy, Linkage Tianyi has a clear understanding. Linkage Tianyi focuses on high-end cylindrical batteries, firmly create cylindrical boutiques; in terms of research and development, Linkage Tianyi has many years of mass production and manufacturing experience in cylindrical and square batteries and fast charging core research and development experience, since the multi-pole ear, fast charging technology and other intellectual property rights, has obtained hundreds of patents, patented technology mainly covers the main cell material, cell structure design, cell processing technology and equipment, etc., the layout covers the whole industry chain technology of the battery.

At present, Linkage has experience in in-depth customized development with a number of international OEMs, and its R&D capabilities have been recognized by many international car companies. Dr. Yang Sitao said: "We believe that if we want to do a good job in cylindrical batteries, we must not follow the work of copying and comparing, but to shake hands with customers and exert creative problem-solving capabilities, Linkage Tianyi will continue to invest in the positive development of lithium batteries, promote the international competitiveness of China's new energy industry with original technology, and help achieve the strategy of manufacturing power and science and technology power in the 14th Five-Year Plan." ”
