While Panasonic has only specified 2022 as a production start target, its battery CEO has stated that “In terms of product development, the technological goals have largely been achieved” and that it expects to receive an order from Tesla as soon as the cell can be put into production. Considering its position within Tesla’s supply network, Panasonic revealed to Nikkei that it had been in discussions with Tesla about the format before the 2020 Battery Day announcement – as such, the Japanese company is likely to have had longer than Tesla’s other suppliers to understand the new format and develop mass production processes for it. Panasonic is Tesla’s main battery supplier and supplies all the cells destined for Tesla vehicles built in North America.

Now, with the proposed September 2021 deadline having passed and Tesla and its suppliers still only at the prototype stage, how much longer will it take to get 4680 cells into new EVs?Įlectric Vehicle Batteries, 2021 Update – Thematic Research At the time, Tesla said it expected to have ironed out production kinks and would be moving into mass production at that point. Back in September 2020, the company stated it already had a pilot line in Fremont, California under its Project Roadrunner plan to develop and optimize the manufacturing process for 4680 cells.

However, the timeline to release the new format has been repeatedly pushed back as Tesla and its suppliers wrestle with the challenge of putting 4680s into mass production. The format was first shown by Tesla at its ‘Battery Day’ in September 2020 and led the automaker to claim that EVs equipped with this cell would travel 16% further than vehicle’s equipped with today’s cell technology.

Tesla’s North American battery partner, Panasonic has shown a prototype of the new 4680-format cylindrical battery cell.
