CURRENT INTERRUPT FOR ELECTROCHEMICAL CELLS
20200365870 · 2020-11-19 ·

To counteract the potentially destructive effects of temperature increases in primary batteries during short circuit conditions, a current interrupt may be positioned within an anode conductive path. The current interrupt may comprise a thermoplastic substrate having a low glass transition temperature, and having a conductive coating thereon to form a portion of the anode conductive path. During a short circuit, the temperature within the battery increases above the glass transition temperature of the thermoplastic substrate, thereby causing the current interrupt to deform, thereby degrading the portion of the anode conductive path defined by the current interrupt, decreasing the amount of current flowing through the anode conductive path, and effectively limiting the temperature increase within the battery interior.
