The joint venture announced by Toyota and Panasonic will develop highly competitive, cost-effective batteries that are safe and feature excellent quality and performance (in terms of capacity, output, durability, etc.), enabling use with peace of mind by all customers. Furthermore, the joint venture will supply batteries not only to Toyota but also, broadly and stably, to all customers.

The joint venture’s name embraces Toyota’s and Panasonic’s strong determination to provide their customerswhile working in unison with many friends to keep our irreplaceable earth-abundant and cleanbroad-ranging, added-value solutions including and beyond the supply of energy in the form of batteries.

The planned start of operations for the JV is April 1, 2020, and will be headed by Hiroaki Koda (Toyota) as Director and President.

Key operations the JV will be involved in are:

  • Development, manufacture, and sales of high-capacity and high-output automotive prismatic lithium-ion batteries,
  • Development, manufacture, and sales of automotive solid-state batteries,
  • Development, manufacture, and sales of next-generation automotive batteries other than those mentioned above (including batteries based on new principles),
  • Ancillary and other operations related to the above.
