Maxell, Ltd. <6810> extended its gains for a seventh straight session. After Thursday's close, Maxell announced that it will begin joint research on all-solid-state batteries with the Japan Aerospace Exploration Agency (JAXA), fueling buying interest.

Maxell was selected for JAXA's "JAXA Space Technology Demonstration Acceleration Program" with a proposal themed "Development and Demonstration of High Heat-Resistant All-Solid-State Batteries to Maximize Spacecraft Mission Capabilities." The joint research aims to achieve an energy density equivalent to conventional lithium-ion batteries, while establishing stable output characteristics and long-life performance across an extremely wide temperature range, such as in space environments, by leveraging the properties of all-solid-state batteries. Under the initiative, Maxell will conduct demonstrations of all-solid-state batteries designed for installation in artificial satellites. Additionally, by adopting all-solid-state batteries, Maxell aims to further reduce spacecraft weight and minimize temperature control equipment, working to achieve both overall weight reduction and enhanced design flexibility.
