Tesla’s getting ready to do a good impression once again on its customers. With Panasonic’s help, a new battery pack will be on the way. The manufacturer has confirmed it would start production in Japan.
Last year we told you that Tesla teamed up with Panasonic for a major improvement in cell technology. They agreed to manufacture next-gen EV batteries and presented some prototypes. This initiative would give the American carmaker a new advantage over its competitors, as both companies aim to make and use these new battery packs in a more cost-efficient environment.

Dubbed as the 4680 format because of their dimensions (46 mm wide, 80 mm tall), this new type of batteries will enter production in March 2024 at only one plant in Japan, as Reuters informed. We should remember this announcement coming from Panasonic. Tesla first talked about a new and revolutionary type of battery in 2020. Two years later we get confirmation that it’ll be another two years before we see them installed in new cars.

Also in 2020, Elon Musk confirmed Tesla would increase its battery cell purchases from Panasonic, LG, CATL, and other possible suppliers. In the end, Panasonic looks like it’s the first company to make them. It’s possible others will follow suit, but for now, the Japanese have made the first real step. The confirmation of production is important for both Tesla and Panasonic.

Initially, Musk calied the involvement in the development of the new battery pack would delay production of the Cybertruck, Semi, and Roadster. He thought and hoped everything would be set for 2022. Now this has been proven to be wrong. Given everything that’s happening in the world, it’s understandable. Good technology that can improve transportation doesn’t just happen overnight.

The 4680 batteries’ tabless design and simpler chemistry will help with the improvement of vertical integration in the production effort. Not only will this help with keeping costs down but will also translate into better-priced cars. Early adopters enjoyed EV transportation, but with this new development on the horizon and SSBs that are to come in 2028, the industry has a real chance of producing cars that have better prices and improved range. Recycling is another key theme that we will follow closely.

Car shows on TV and his father's Fiat Tempra may have been Florin's early influences, but nowadays he favors different things, like the power of an F-150 Raptor. He'll never be able to ignore the shape of a Ferrari though, especially a yellow one.
