Abstract
A heat-sensitive material comprising a heat shrinkable material (e.g., a heat shrinkable resin) having dispersed therein electrically conductive particles, which shrinks on heating to allow an electric current to flow. A heat-sensitive element comprising the heat-sensitive material and a pair of electrode terminals is useful as an over-charge protective element of lithium ion secondary batteries.

A heat-sensitive material comprising a heat shrinkable material having dispersed therein electrically conductive particles.
A heat-sensitive element comprising a heat-sensitive material and a pair of electrode terminals, wherein the heat-sensitive material comprises a heat shrinkable material having dispersed therein electrically conductive particles.
A process for producing a heat-sensitive element comprising a cylindrical heat-sensitive material and a pair of electrode terminals, the heat-sensitive material comprising a heat shrinkable material having dispersed therein electrically conductive particles, which comprises:
- inserting an electrode terminal to each opening end of the cylindrical heat-sensitive material;
- and
- subjecting both ends of the cylindrical heat-sensitive material to heat shrinkage so as to integrate the electrode terminals with the cylindrical heat-sensitive material.
