Panasonic Energy Ready for Large-Scale Production of Next-Gen EV Batteries!

Panasonic Energy, a key supplier for Tesla, is set to begin mass production of its high-capacity 4680 electric vehicle (EV) batteries. With preparations complete, the company’s Wakayama facility in Japan will serve as the primary site for manufacturing these advanced cells, which offer five times the capacity of their predecessor, the 2170 cylindrical batteries.

Designed to significantly boost EV driving range and reduce the number of cells required per battery pack, the new 4680 cells measure 46mm in diameter and 80mm in height. These cells are anticipated to elevate EV performance, allowing automakers to extend vehicle range with fewer battery cells.

Panasonic has already sent samples to several automakers and plans to commence full-scale production after receiving client approvals. Initially projected to start production in the first half of the business year (beginning in April), the company expects the new batteries to address ongoing challenges in the EV market, particularly for Tesla, which has experienced production hurdles with its own 4680 batteries.

In addition to the Japanese facility, Panasonic is expanding its global operations with a second battery plant in Kansas, expected to begin production next year, complementing its Nevada plant. The company aims to start production at several gigawatt-hours annually and will employ 400 staff at the Wakayama plant by March 2025, making it a key hub for future battery production innovations.

This new development marks a significant step forward for Panasonic as it strengthens its position in the rapidly growing EV market.
