The battery insulation sheet includes paper insulation sheet and plastic insulation sheet (paper). It is a battery component that avoids the short circuit of the positive and negative electrodes of the battery. It has various shapes. Separate groups, flakes, are strongly called excellent films. The military energy ring referred to in many battery products is the type of battery insulating film referred to in the industry, which can be called an insulating ring. (Plastic type) is also the gap between the pole pieces. Separate the positive and negative plates. Avoid short-circuiting of the battery. The insulating film plastic film. There are pVC pc. pet. pp and so on.

The battery insulation sheet has the following characteristics:

(1) It has electronic insulation to ensure the mechanical separation of positive and negative poles;

(2) There are fixed hole names and holes to ensure low resistance and high ionic conductivity, which has a good passability to Li Nanzi

(3) Since the solvent of the electrolyte is a strong polar organic compound, the barrier must be resistant to electrolyte corrosion and have sufficient chemical and electrochemical stability

(4) Good wettability to electrolyte and sufficient ability to absorb and keep warm

(5) It has sufficient mechanical properties, including wear strength and tensile strength, but the thickness is as small as possible

(6) Space stability and good war integrity:

(7) Good thermal stability and automatic shutdown maintenance performance.
