Abstract
A separator for a rechargeable electrochemical cell has a conductive first layer and a non-conductive second layer. The non-conductive second layer and the conductive first layer are adhered to one another, wherein the non-conductive second layer has a melting point below a critical temperature for the rechargeable electrochemical cell and discharges the cell when subject to overheating.
Claims11
A separator for use in a rechargeable electrochemical cell to prevent an uncontrolled reaction in the rechargeable electrochemical cell upon overheating comprising:
- a conductive first layer;
- and
- a non-conductive second layer, the non-conductive second layer and the conductive first layer are adhered to one another, wherein the non-conductive second layer has a melting point below a critical temperature for the rechargeable electrochemical cell.
