Kyocera Corporation (President: Hideo Tanimoto; “Kyocera”) and Maxell, Ltd. (President: Keiji Nakamura; “Maxell”) started running test operations as of December 2025, installing power modules utilizing Maxell’s all‑solid‑state battery “PSB401010H” in industrial robots and controllers at Kyocera’s Kagoshima Sendai Plant, one of its semiconductor ceramic package production sites.
The ceramic‑packaged all‑solid‑state batteries produced by Maxell feature high reliability*1, and their exterior housings adopt ceramic packages manufactured by Kyocera. With its superior heat resistance and hermeticity*2, this package contributes to the high reliability*1 of all‑solid‑state batteries, exceeding that of conventional batteries using liquid electrolytes.
In the manufacturing processes of industrial products, the majority of industrial robots use power modules equipped with primary (non‑rechargeable) batteries for memory retention during power outages and for real‑time clock (RTC) functions to support factory automation. Power modules that use primary batteries generally require replacement every one to two years, and the used batteries become industrial waste each time.
Replacing primary batteries with a rechargeable all-solid-state battery PSB401010H provides over 10 years of service life, reduces battery replacements and waste, and maintains high safety*1 even in harsh manufacturing environments.
Based on test operations conducted at its factories, Kyocera will consider introducing technologies that further reduce maintenance requirements and lower environmental impact at its manufacturing sites.
Leveraging its analog core technologies, Maxell will continue to advance the development of high‑performance and highly reliable all‑solid‑state batteries and modules along Four Key axes—high reliability, high heat resistance, high output, and large power supply capacity—targeting not only existing applications but also new application areas where conventional batteries could not be used, with the aim of addressing a wide range of societal challenges.
Kyocera and Maxell will further strengthen their cooperation in the field of all‑solid‑state batteries and related technologies, contributing to the resolution of societal challenges in a broad range of applications, including industrial uses.
