BAK Battery, one of the Chinese lithium-ion battery manufacturers, has unveiled at the 2021 China International Battery Fair (CIBF) exhibition an all-new 4680 cylindrical cell, which is the first cell of this type in China.
The company is one of the Chinese pioneers of cylindrical batteries so the push for the 4680-format (introduced by Tesla at the Tesla Battery Day) is probably a natural next step.
According to Chinese media, BAK Battery was working on a cylindrical cells bigger than 2170 (aka 21700) for quite some time and already offers 32105 and 32140 models (tabless design, in three versions: NCM, LiFePO4 and LiMn2O4).
The new BAK Battery 4680 cell of undisclosed chemistry has a capacity of 25 Ah (compared to about 3 Ah of the 18650).
