Lithium battery drying aid

摘要

A method for fabricating lithium batteries comprising providing a P2O5 drying aid between an exterior surface of a cell laminate and an interior surface of a container in which the cell laminate is sealed. A cell laminate is first formed from a transition metal chalcogenide positive electrode and a carbonaceous negative electrode with an electrolyte-containing separator there between. The cell laminate is then sealed in a container together with the P2O5 drying aid such that P2O5 is available during battery operation to react with moisture generated during charging and discharging of the battery cell.
