ABSTRACT:
A small battery cell including a pressure relief and spring disengagement device which vents various internal pressures to the atmosphere to prevent cell bulging or explosion, and also which internally interrupts current flow through the cell due to internal cell over heat, excessive current flow or the like. Internal reconnection of cell members reoccurs subsequent to internal thermal or other internal abnormalities. Alternate embodiments illustrate an apparatus and method for vacuum assisted filling and an apparatus for vacuum sealing of the small battery cell.
