Thank you, Mr. Air, a netizen of CTOnews.com, for your clue delivery! CTOnews.com December 16 news, Yiwei LiNeng headquarters R & D center was officially completed in Huizhou yesterday (December 15), with an investment of more than 2 billion yuan and a construction area of 145000 square meters. It took a total of 16 months from the start of construction in August 2021 to the completion of construction in November 2022.

Online, Yiwei Lithium Energy simultaneously released new technologies and new products on large cylindrical batteries, "π" battery systems, lithium metal secondary batteries, solid-state and sodium ion batteries, and hydrogen energy technology.

Specifically, Yiwei Lithium has released a research and development sample of a new generation of large cylindrical batteries with an energy density of 350Wh/kg and a 9-minute ultra-fast charge. According to reports, while the battery performance has reached a new high, the large cylindrical pilot line independently developed by Yiwei Lithium Energy has produced more than 500000 samples, with an overall excellent rate of 92%.

CTOnews.com learned that Yiwei Lithium Energy released the "π" battery system at the same time. Yiwei lithium energy data show that on the basis of CTP integration technology, the application of highly efficient composite new materials and new adhesives, the "π" battery system reduces weight by 10%, and the energy density is as high as 260Wh/kg.

In addition, Yiwei LiNeng has also released lithium metal secondary batteries, solid-state and sodium ion batteries, and hydrogen energy technology. Among them, Yiwei lithium can be based on layered oxide cathode and hard carbon negative electrode, C40 aluminum shell as the carrier, designed a large cylindrical sodium ion battery, the specific energy can reach 90% 135Wh / Kg,10C capacity retention rate of 40 ℃ can still work normally, cycle 2500 times 80% capacity retention rate; currently with the end customers in the preparation work before the pilot test.
