NASA Successfully Upgrades Space Station's Power System After Efforts of Several Years


NASA said, the primary power system of the International Space Station (ISS) has now been fully upgraded to lithium-ion technology. The space station's primary power system originally used nickel-hydrogen batteries for storage.

Upgrades to the space station are designed to maximise the capability of the orbiting laboratory to support scientific research and technology development.

The new batteries were provided by Boeing, who also worked with Aerojet Rocketdyne and others for certain components. The space-grade lithium-ion cells were provided by GS Yuasa Lithium Power. One lithium-ion battery and corresponding adapter plate replaces two nickel-hydrogen batteries.

In 2009, the International Space Station Programme conducted a preliminary risk and feasibility study to evaluate the use of lithium-ion batteries to replace the power storage system. In early 2011, the programme approved the development of the new battery. Production started in late 2014, and in December 2016, NASA began the process of replacing the aging batteries with new lithium-ion batteries.
