Tesla has already replaced the Chinese Model 3 sedan with an LFP battery.It also that New 4680 cell format This will be a big part of the future for companies with higher energy density products such as semi and cyber trucks. As a result, Tesla alters both the chemistry and physical size of cells.

Tesla renews its long-standing commitment with battery suppliers Panasonic Last year, LG seems to have the potential to win more automakers’ businesses in the future.

In the March report, LG also Trying to build a cell in 2170 formatThe type used in the current Tesla EV-is in the United States, indicating that the partnership between the two companies may not be limited to vehicles for the Chinese market. Tesla modifies battery chemistry for Chinese Model Y
