Satellite Batteries That Withstand 100°C Developed in Japan

Innovative Battery Technology for Spacecraft

According to НВ — Техно: Japan's Aerospace Exploration Agency (JAXA), in partnership with the electronics firm Maxell, is working on a new generation of solid-state batteries designed for satellites. These power units are engineered to operate reliably at temperatures exceeding 100°C, a significant leap from current capabilities. This breakthrough could eliminate the need for conventional thermal management systems, greatly simplifying satellite design and reducing overall weight.

Prototypes of these advanced cells are scheduled for testing aboard small satellites, marking a pivotal milestone in the evolution of space technology.

Key Benefits of the New Battery Design

The core innovation involves swapping out liquid electrolytes for solid materials, which enhances both the safety and reliability of the batteries in the harsh environment of space. Crucially, these new power sources maintain an energy density comparable to standard lithium-ion batteries-a notable engineering achievement. As a result, satellites will be equipped with high-temperature-resistant batteries capable of enduring extreme environmental conditions.
