URL copied Multi-year effort to upgrade space station batteries bears fruit After 13 different astronauts conducted 14 spacewalks over several years, the primary power system of the International Space Station (ISS) has now been fully upgraded to lithium-ion technology, NASA has said. The space station s primary power system originally used nickel-hydrogen batteries for storage, the US space agency said on Tuesday. 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 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.
