Large scale lithium-ion battery cells for space use

High energy density lithium-ion batteries are expected to become the battery of choice for the next generation satellite and other space usage. Japan Storage Battery Co., Ltd. (JSB) has developed large capacity lithium-ion battery cells through cooperation with Mitsubishi Electric Corporation (MELCO). The cells (rated capacity: 50-190 Ah) are completely sealed, achieved with a ceramic hermetic seal. The electric performance and environmental durability of the cells have been evaluated. The results demonstrate the cells excellent performance at all the tests, and confirm that the cells can satisfy the requirements of satellites and rockets applications.
