Development and on-orbit operation of lithium-ion pouch battery for small scientific satellite “REIMEI”

- A lithium-ion pouch battery was developed and launched with a small scientific satellite “REIMEI.”
- Life performances of pouch cells potted with polyurethane or epoxy resin were evaluated in vacuum.
- The cells potted with epoxy resin showed better performance because of epoxy's lower permeability.
- The battery trend in orbit was in good agreement with corrected laboratory test results.
- The pouch cell battery was not inadvertently affected by conditions in space.
