Toyota Partners With Idemitsu To Mass-Produce All-Solid-State Batteries

Toyota Motor Corporation TM has entered into an agreement with the Japanese petroleum company Idemitsu Kosan Co Ltd to work together in developing mass production technology of solid electrolytes.

The association will strive to improve productivity and establish a supply chain to achieve the mass production of all-solid-state batteries for battery electric vehicles (BEVs).

Through the partnership, the two companies will seek to ensure the successful commercialization of all-solid-state batteries in 2027-28.

The agreement follows an announcement by Toyota in July that it has achieved a technological breakthrough enabling a potential halving of the weight, size and cost of batteries, signaling a significant advancement for electric vehicles.

The collaboration focuses on sulfide solid electrolytes, which are seen as a promising material to achieve high capacity and output for BEVs.

The parties will aim to develop sulfide solid electrolytes and mass produce them using Idemitsu’s large pilot facility.
