Product Details

The P13M40 heat‑absorbing sheet is a phase‑change material used for thermal management of battery cells. It provides thermal control at the interface, thereby mitigating localized temperature fluctuations caused by cell operation.
Product features: Achieves phase-change heat absorption and release within the 40–55°C range, enabling repeated cycling.
Application areas: Used at the tab and busbar locations of fast‑charging batteries and large‑size single cells; it can serve as a thermal management material, enabling temperature buffering within the 40–55°C range at the application site, reducing the heating rate of the protected components, and improving the operating ambient temperature.
