Lithium ion battery separator film

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.

Specification of lithium battery separator film

Advantages of separator film for lithium ion batteries

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

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

03

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

Good Thermal Conductivity

04

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