Development of cylindrical all-solid-state battery (PSB23280) that can also be applied to main power applications

Maxell, Ltd. (President and Representative Director: Keiji Nakamura / hereafter, “Maxell”) is developing a 200mAh cylindrical all-solid-state battery with 25 times the capacity of a ceramic packaged all-solid-state battery (PSB401010H) that uses a sulfide-based solid electrolyte and has been in mass production since June 2023. The PSB23280 cylindrical all-solid-state battery achieves its large capacity due to a newly-developed cylindrical exterior body with high sealability, while retaining long-term reliability and heat resistance equivalent to those of existing products.
