Maxell Develops All-Solid-State Battery Power Module Compatible with ER Battery Size - CleanTechnica

Maxell has developed an all-solid-state battery power module that matches the size and output voltage (3.6V) of the commonly used lithium thionyl chloride (ER) battery. ER batteries are widely employed in industrial equipment backup systems, smart meters, and IoT sensors but are primary (non-rechargeable), necessitating frequent replacements that increase maintenance workload and generate waste. Maxell’s new module fits within the standard ER battery dimensions (17.9 mm diameter, 50 mm height) and incorporates eight mass-produced “PSB401010H” cells to provide approximately 35 mAh capacity. It also includes an integrated charging circuit (charging at 5V), enabling easy adoption as a rechargeable replacement for ER batteries. By using this all-solid-state battery module, industries can reduce battery replacement frequency, thereby lowering maintenance time and increasing equipment operating hours, which enhances productivity. Additionally, the rechargeable nature of the module helps minimize environmental impact by reducing waste battery disposal. Maxell is focusing
