Yiwei Lithium can release 46 series of large cylindrical lightweight battery pack: equipped with the latest "π system", ultra-low internal resistance structure

Thanks to CTOnews.com netizens for the delivery of clues about the past. CTOnews.com June 25 news, Yiwei Lithium can participate in the EUROBIKE 2023 European Bicycle Show in Frankfurt, Germany, the first release of 46 series of large cylindrical lightweight battery pack.

The battery pack uses 46 large cylindrical cells of Yiwei lithium car gauge class, adopts all-polar ear technology, and is equipped with the latest "π system". It claims to have ultra-high energy density and ultra-low internal resistance structure to match light power demand.

It is understood that the "π system" uses π-type three-sided liquid cooling technology, which can solve the problem of fast charge and heat, and realize "extremely fast charging" of the battery system; based on CTP integrated technology, combined with new materials, the system can lose 10% of its weight and achieve "small space, low weight, and high battery life".

CTOnews.com obtained from the exhibition that Yiwei Lithium can demonstrate the comprehensive solutions of cylindrical batteries such as 18650, 21700, 33140 and 40135, which can match the application needs of electric two-wheelers, electric bicycles, electric motorcycles, scooters, balance cars and other light traffic scenarios.

It is worth mentioning that the Yiwei LiNeng 4695 cylindrical battery will be mass-produced and delivered in the third quarter of this year, using 3-4C fast charging core and large surface liquid-cooled temperature equalizing technology to support ultra-fast charging; combined with all-polar ear structure and nickel + silicon-carbon material system, high energy density of 350Wh/kg can be achieved.
