The separator is one of the core components to ensure battery safety, and its thermal stability directly affects the safety performance of the battery under extreme temperature conditions. The thermal nail penetration test simulates high-temperature puncture scenarios to evaluate the separator's anti-perforation ability and thermally induced pore characteristics under thermal shock.
·The thermal spike tester for isolating membrane is based on a high-precision servo control system and integrates a high-precision temperature control module. It conducts visual dimensional evaluation of the thermal radiation impact area at different distances from the isolating membrane to evaluate the thermal stability characteristics of the isolating membrane.

1. Evaluation of thermal stability of different isolation films ·PE-based film has poor thermal stability: it is easy to melt and shrink under high-temperature nail puncture,the hole expands significantly, and there is a risk of thermal runaway; ·PI modified film has good thermal stability: the hole structure can still be maintained intact at high temperatures,which means it has higher heat resistance and safety.
| 2. Thermal stability evaluation of isolation films of different thicknesses Diaphragm A is thinner than Diaphragm B. At the same temperature, the thicker the diaphragm, the less likely it is to melt and shrink, and the less significant expansion of the holes, indicating that it has higher heat resistance and safety.
