Li-ion cells to be delivered to the International Space Station

16 October 2018

The International Space Station

The GS Yuasa lithium-ion batteries will replace older nickel-metal hydride cells currently installed in the International Space Station. Only half the number of Yuasa cells are needed to provide the same capacity and high-energy density of their predecessors.

Therefore, contributing to a reduction in transportation costs, just 24 of these new lithium-ion cells will deliver the same performance provided by 48 nickel-metal hydride batteries.

GS Yuasa’s lithium-ion cells have high-energy density and long life; plus, they boast a track record of being installed in numerous spacecraft and rockets, both in Japan and abroad. First adopted on-board the ISS in 2012, the cells have a design optimised for space operations, which require highly efficient charge-discharge.

All energy on-board the ISS is produced by solar panels and stored in the spacecraft’s batteries. This stored energy is then used to power the spacecraft’s systems during nocturnal periods – of which there are 16 every 24 hours, due to the ISS’s orbit around the earth.

The replacement of the batteries will be carried out by astronauts during space walks outside the space station, scheduled to take place this October.

GS Yuasa will continue to contribute to space development projects through the development and manufacturing of high-performance lithium-ion batteries.

GS Yuasa leads the world with innovative power solutions – ranging from the manned research and submersible ‘Shinkai6500’, to high-performance batteries used in automobiles, motorcycles, marine, rail, and aviation applications, including the state-of-the-art Boeing 787 Dreamliner.
