Description

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

In 2021, high voltage and high power ∗1 We will develop a “bipolar all-solid-state battery” with these features to meet the diversifying needs of the market.

  • High voltage, high output: Comparison with coin-type all-solid-state batteries announced in September 2020
