Panasonic Holdings' energy unit has finalized preparations for the mass production of its 4680 electric vehicle (EV) batteries. The company announced that its renovated plant in Wakayama will serve as the primary factory for producing these advanced cells, which boast five times the capacity of the smaller 2170 cylindrical batteries¹.

The 4680 cells are expected to significantly enhance the driving range of electric vehicles while reducing the number of cells needed to achieve the same battery pack capacity. This innovation marks a crucial step forward in the EV industry, as automakers strive to improve efficiency and performance.

Panasonic Energy has already sent samples of the 4680 batteries to some of its automotive partners and plans to commence production once it receives approval from these clients. The company aims to start production within the first half of the current business year, which began in April.

The Wakayama plant is projected to employ around 400 staff members by March 2025, focusing on the development and production of the new batteries. This facility will also serve as a testing ground for processes that could be implemented at other battery factories worldwide.

Panasonic Energy currently manufactures 2170 and 1860 cylindrical EV batteries at its Suminoe and Kaizuka plants in Japan. The addition of the 4680 cells to its production lineup underscores the company's commitment to advancing battery technology and supporting the growing demand for electric vehicles.
