Electrolyte-Binder Powder Processing to Improve Manufacturability of Thermal Battery Separator Pellets

摘要

Thermal battery electrolyte-binder powder processing was investigated with design-for-manufacturing considerations with attempt to improve separator pellet production. Low separator pellet yields increase manufacturing costs and waste valuable or expensive battery materials. Alternative powder blending and sizing processes are reviewed and their impact on powder flow and compaction characteristics discussed. Reprocessing scrapped separator pellets was demonstrated to be a viable process to reclaim scrapped materials through mechanical and electrochemical test results.
