According to reports, the SpEED series of fast-charging power lithium batteries announced by Linkage Tianyi this time have a single cell energy density of 260Wh/kg, which can achieve a range of 400 kilometers after 8 minutes of charging. The number of fast-charging cycles can reach 800 to 1,200 times. Charging time will be further shortened to 5 minutes in 2025. In addition, the cylindrical/square battery cells of the SpEED series products are all high-nickel chemical systems, and the cell level has good safety. After forming a module/system, it can achieve NTp (no thermal runaway).

　　According to Dr. Liu Guanwei, the company's chief strategy officer, the company has a R&D product team of hundreds of people. In the past three years, it has been investing heavily in the development and mass production preparations for the next generation of high-performance lithium-ion batteries. Its current technical advantages come from its unique Full-stack battery cell technology, the positive electrode is compositely wrapped with fast ion conductors and interface stabilizers, with a nickel content of up to 88%, which greatly increases the energy density and ionic conductivity, and can stabilize the solid-liquid interface; the negative electrode uses nano-sized silicon particles Control, the silicon content can reach 10%, which can greatly improve the lithium ion reactivity; by adding special electrolyte, the battery stability, rate capability, service life and cycle times can be greatly improved.

　　Yan Zidian, chairman of Lianyi Tianyi, said that as the company's milestone star product for several years, SpEED fast-charging power lithium battery has already received large-scale orders from many European and domestic luxury passenger car brands, and will be fully launched in 2023. Achieve mass production. While steadily developing new energy vehicle markets at home and abroad, Linkage Tianyi will rely on its strong R&D capabilities, adhere to fast charging as its core positioning to drive product development, and create a leading brand for fast charging lithium-ion batteries.
