COVER PLATE FOR A BATTERY CELL ARRANGEMENT

Abstract

A battery cell assembly comprises a cell cap head with an outer circumference and an outer surface. The outer surface of the cell cap head defines a pressure vent. The battery cell assembly also comprises a housing constructed from a housing material. The housing comprises a base, at least one side, and an opening. The at least one side connects the base to the opening of the housing. The battery cell assembly includes a cap plate cover constructed from a cell cap plate material and positioned to cover at least a portion of the outer surface of the cell cap head. The cap plate cover defines a top plate that includes a vent shaped to conform to the pressure vent. The melting point of the cell cap plate material is higher than the melting point of the housing material.
