Last mobth, Kyocera and Maxell started running test operations installing power modules using 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, and their exterior housings adopt ceramic packages manufactured by Kyocera. With superior heat resistance and hermeticity, this package contributes to the high reliability1 of all‑solid‑state batteries, exceeding that of conventional batteries using liquid electrolytes. 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 safety1 even in harsh manufacturing environments.
