Panasonic: Tesla pushing for faster development of 4680 cells – Green Car Reports


Tesla is pushing for faster development of new 4680 battery cells, the CFO of battery supplier Panasonic said in an interview with Bloomberg published Wednesday.
Hirokazu Umeda noted this in a briefing after the release of Panasonic’s quarterly financial results, while noting that the Japanese company is still seeing stronger demand from Tesla for the current 2170 cells.
The 4680 cells—which are longer and wider than the 2170 cells while retaining a cylindrical form factor—have been championed by Tesla CEO Elon Musk as the key to unlocking cheaper electric cars, as well as more power-intensive applications like the Tesla Semi and Cybertruck. Panasonic is also betting the new technology will pave the way to supply other automakers beyond Tesla.

Future Tesla cell will make energy, power gains
Panasonic has been scouting locations in Oklahoma and Kansas for a United States factory to build the 4680 cells, Bloomberg reported in March. But there were no updates in Panasonic’s quarterly earnings call and, earlier this year, the company confirmed that it will make the new format initially in Japan.
The company will likely need to ramp-up production as it addresses technical challenges of manufacturing the new cells. Last year it became clear that multiple battery suppliers would be willing to make the new format. Panasonic, however, last fall said that making them “requires new techniques.”
Tesla has reached a cumulative million 4680 cells made at its pilot facility, although that’s nowhere close to what’s needed to supply Model Y and Model 3 production, which is the automaker’s interim goal. Musk suggested in April 2021 that the cells were not more than 18 months away from volume production.

Volkswagen reportedly didn’t approach its U.S. dealers ahead of the decision to create its Scout SUV brand—which leads to all sorts of questions about how it plans to sell these EVs.
The first electric vehicle from Cadillac also promises to be exceptionally quiet, luxurious, and fast-charging.
EVs remain the antidote for high gas prices. Expectations are high for electric RVs, but where will they charge? And the weight of bigger battery packs causes more emissions from a source you might not expect. This and more, here at Green Car Reports. Bigger batteries for electric vehicles can…
Electricity costs are also less volatile than oil prices, so EV operating costs are more likely to remain stable over time.
