The application of PET hot pressed film in new energy batteries is becoming increasingly widespread, and its importance cannot be ignored. The following is a detailed explanation of the application of PET hot pressed film in new energy batteries:

1、 Application background

With the rapid growth of the electric vehicle market and the increasing demand for energy storage systems, the safety and performance stability of new energy batteries as core components have become the focus of industry attention. PET hot pressed film has become an indispensable component in new energy batteries due to its excellent electrical insulation performance, chemical stability, and heat resistance.

2、 Application advantages

High insulation performance: PET hot pressed film has good electrical insulation performance, which can effectively isolate the electrical components inside the battery, prevent safety hazards such as short circuits and electric shocks.

Excellent heat resistance: New energy batteries generate a large amount of heat during charging and discharging, and PET hot pressed film can withstand high temperature environments to ensure stable operation of the battery.

Chemical stability: PET hot pressed film has excellent resistance to various chemicals, which can protect the battery from chemical corrosion.

Lightweight design: PET hot pressed film has a lighter weight and thinner thickness, which helps reduce the volume and weight of the battery pack and improve the energy density of the battery.

3、 Application scenarios

CCS integrated busbar: PET hot press film plays multiple roles in insulation, support, buffering, and bonding in CCS integrated busbar. By using hot pressing technology to press and form raw materials such as signal acquisition components, aluminum bars, and insulation films, a lightweight and highly integrated CCS integrated busbar is formed, which helps to improve the space utilization and production efficiency of battery modules.

Cell interval thermal pad: PET thermal pressure film can also be used as a thermal insulation pad material between cells, effectively isolating the diffusion of heat to surrounding cells when a single cell experiences thermal runaway, and protecting the normal operation of surrounding cells.
