Advantages of Battery Barrier Film

The Film Is Easy To Break Down Under High Current
The Film Is Easy To Break Down Under High Current
01

The coating expands when heated, blocking the micropores of the film to avoid short circuit, and has good flame retardancy to avoid thermal runaway of the battery.

High Temperature Resistance Of The Film
High Temperature Resistance Of The Film
02

Improve the high temperature resistance of the film, so that it can still ensure the integrity of the diaphragm at 180 ℃.

Improve The Rate And Cycle Performance
Improve The Rate And Cycle Performance
03

The nano-coating can form a solid solution in the lithium battery to improve the rate and cycle performance.

Good Thermal Conductivity
