Cell design for spirally wound rechargeable alkaline metal cell

Patent ·
OSTI ID:7168988
This patent describes an improvement in a rechargeable electrochemical cell having a cell casing housing stack of spirally wound elements which include an alkaline metal anode, a cathode or cathode collector and a separator. The improvement comprising increasing the usable life of the rechargeable electrochemical cell by preventing lithium dendrites from forming on any surface within the cell casing external to the stack of spirally wound elements by maintaining the casing at substantially the same potential as the alkaline metal anode and providing the cell casing with an insulative, inert liner.
