Coin type & bipolar type all-solid-state batteries

Coin type all-solid-state battery

The coin type all-solid-state batteries are developed by combining the development and manufacturing know-how of lithium-ion batteries and micro batteries that Maxell has cultivated over many years.

In 2021, Maxell developed the bipolar type all-solid-state battery with features of high voltage and high output∗1 to respond to variety of market needs.

  1. High voltage and high output: Comparison with the coin type all-solid-state battery released in September 2020.
