Using precision coating equipment, prepare a layer of 2-3μm coating on the Porous polyethylene/polypropylene film, which is composed of water, organic additives and inorganic substances.

Advantages of lithium ion battery separator film

The Film Is Easy To Break Down Under High Current

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

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

Improve The Rate And Cycle Performance

The nano-coating can form a solid solution in the separator film for lithium ion batteries to improve the rate and cycle performance.

Good Thermal Conductivity

Solve the problem of thermal conductivity of PP/PE materials.
