Summary points:

  • Maxell Ltd. introduces a solid-state battery power module matching the size (17.9 mm × 50 mm) and 3.6-volt output of standard lithium thionyl chloride (ER) batteries.
  • The module combines eight PSB401010H all-solid-state cells for about 35 mAh capacity, with a built-in 5-volt charging circuit.
  • Designed for backup power in industrial equipment, smart meters, and IoT sensors, the module helps cut battery replacements, lower maintenance time, and extend operating life.

TOKYO – Maxell Ltd. in Tokyo is introducing a solid-state battery power module for industrial equipment backup systems, smart meters, and internet of things (IoT) sensors.

The battery power module matches the same size and output voltage as a lithium thionyl chloride battery (ER battery).

This module features a circuit designed to match the 3.6-volt output voltage of ER batteries, housed in standard ER battery size-compatible casing 17.9 millimeters in diameter and 50 millimeters high.

Eight batteries

It incorporates eight mass-produced PSB401010H all-solid-state batteries to provide a capacity of about 35 milliampere-hours, with the 5-volt charging circuit integrated within the module.

Adopting this module as a backup power source for industrial equipment helps reduce battery replacement frequency, decrease maintenance time, and increased operating hours. For more information contact Maxell online at https://biz.maxell.com/en/rechargeable_batteries/allsolidstate.html.
