Maxell starts joint research with JAXA on all-solid-state batteries

Maxell, Ltd. has been selected by JAXA for the "JAXA-STEPS" program to demonstrate high heat-resistant all-solid-state batteries for spacecraft. Currently, widely used liquid lithium-ion batteries require special temperature management equipment because they degrade at around 60°C and pose fire risks above 100°C, increasing spacecraft weight and limiting design freedom. Maxell's all-solid-state batteries maintain high safety even above 100°C. By utilizing these batteries, the joint research aims to minimize the need for temperature management systems, thereby achieving both overall spacecraft weight reduction and improved design freedom. Maxell plans to continue developing highly reliable all-solid-state batteries with long life, high heat resistance, high output, and large capacity.
