Kyocera Corporation has begun testing industrial robots powered by all-solid-state batteries at its Kagoshima Sendai Plant in Japan.

The test deployment, which started in December 2025, involves installing power modules using Maxell’s PSB401010H all-solid-state battery in industrial robots and controllers at the plant. The batteries feature high reliability due to their ceramic packages, manufactured by Kyocera, which provide superior heat resistance and hermeticity.

The use of primary (non-rechargeable) batteries is common in industrial products, but they require replacement every one to two years and generate waste. All-solid-state batteries, on the other hand, can last over 10 years with minimal maintenance and reduce environmental impact.

Kyocera will consider introducing technologies that further reduce maintenance requirements based on test operations conducted at its factories.

Maxell is continuing to develop high-performance all-solid-state batteries for high reliability, high heat resistance, high output, and large power supply capacity. The goal is to address societal challenges in various applications, including industrial uses.
