Linkage releases fast-charge lithium battery -Lithium - Ion Battery Equipment

Recently, Linkage E-Surfing held a 2021 new product announcement conference in Shanghai, and announced the SpEED series of fast-charging power lithium batteries representing the highest-end technology of Link-E-Surfing.

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, a battery life of 400 kilometers after 8 minutes of charging, and a fast charging cycle of 800 to 1200 times. The charging time will be further reduced to 5 minutes in 2025. In addition, the cylindrical/square cells of the SpEED series are all high-nickel chemical systems, and the single-cell level of the cells has good safety, and can achieve NTp (no thermal runaway) after forming a module/system.(Lithium - Ion Battery Equipment)

Dr. Liu Guanwei, the company's chief strategy officer, introduced that the company has a R&D product team of hundreds of people. In the past three years, it has been investing in the development and mass production of next-generation high-performance lithium-ion batteries on a large scale. The current technical advantages come from unique products. Full-stack cell technology, the positive electrode field is wrapped with fast ion conductor and interface stabilizer, and the nickel content is as high as 88%, which greatly improves the energy density and ionic conductivity, and can stabilize the solid-liquid interface; the negative electrode field uses nano-silicon particle size Control, the silicon content can reach 10%, which can greatly improve the reactivity of lithium ions; by adding a special electrolyte, the battery stability, rate capability, service life and cycle times can be greatly improved.

It is understood that in 2025, 10GWh of linked Tianyi orders has been locked, and it is expected that there will be 20GWh of new orders.

Yan Zidian, chairman of Lianhe Tianyi, said that as a milestone product of the company for several years, the SpEED fast-charging power lithium battery has received large-scale orders from many luxury passenger car brands in Europe and China, and will be fully deployed in 2023. mass production. While steadily developing the new energy vehicle market at home and abroad, Linkage Tianyi will rely on its strong research and development capabilities, insist on fast charging as the core positioning to drive product development, and create a license for fast charging lithium-ion batteries.
