Panasonic will postpone the start of the commercial production of its 4680 battery cells for Tesla to April to September 2024, as it aims to improve performance.

The original plan is to start volume production between April 2023 to March 2024.

Panasonic, which said it will introduce performance improvement measures that will further enhance competitiveness, is running a pilot 4680 production line at its Wakayama factory in Japan.

Meanwhile, Tesla is already producing the 4680 battery cells, which it uses in its base Model Y and is touted by Musk as being key to making cheaper and more compelling electric cars. But the carmaker struggled to meet cell production and performance targets.

Tesla makes 4680 battery cells at its factories in California and Texas for over 1,000 cars per week as of the end of 2022.

According to Tesla executive Drew Baglino, the company plans to steadily ramp up production of 4680 battery cells ahead of Cybertruck production next year.

LG Energy Solution, Tesla's South Korean supplier, said last month that it planned to set up a new 4680 production line at its domestic factory by the end of this year, but did not say when the batteries would start volume production.
