We've heard that from Musk before, and the saga of these cheaper, more powerful Panasonic batteries has been thoroughly documented. Panasonic says the soda can-sized battery has taken immense effort to get right, but that it is nearing the finish line.
Panasonic says it will start production of the new 4680 battery cells in April next year, with plans to establish new facilities to make the batteries already in the works. Both of those new facilities will be located at Panasonic's Wakayama factory in Japan. Right now, the electronics manufacturer says it is also working on setting up a prototype production line in Japan. For now, Tesla appears to be happy with these more powerful, more economical batteries, saying that the cells meet the standards the brand has set forth.
While those factories in Japan will be critical to supplying Tesla with the new battery cells, there could also be some Stateside facilities in the coming years. Recent reports now suggest that Panasonic is looking at a new US-based facility for these batteries. We imagine that will be done in partnership with Tesla, with batteries being built near Tesla's existing manufacturing infrastructure to save on costs.
