1. The insulating glue for the lithium ion battery is characterized by being prepared from the following raw materials in parts by weight: 15-30 parts of epoxy resin, 6-10 parts of organic silicon resin, 10-14 parts of epoxy resin curing agent, 3-5 parts of nitrile rubber, 4-8 parts of triethanolamine and 10-30 parts of inorganic filler.

Technical Field

The invention relates to the technical field of lithium ion battery insulation, in particular to an insulating glue for a lithium ion battery.

Background

Lithium ion battery is after the pole piece assembly, negative pole piece dressing district must all surpass the dressing district of positive plate in length and width direction to guarantee the capacity performance and the security performance of battery, consequently, at the width direction of pole piece, the width of positive plate must be less than the width of negative pole piece, after pole piece welding metal utmost point ear, positive pole ear has partial metal to surpass positive pole piece width, but within the coverage of negative pole piece, must appear surpassing partial positive pole ear metal and negative pole piece edge contact of positive pole piece in coiling assembly process. In order to avoid the serious safety problems of short circuit, heating, combustion and the like of a battery caused by the contact of the welding positions of the tabs at the head parts of the positive and negative pole pieces after assembly, the part is coated by green glue commonly used in the industry, but the green glue is high in price, complex in process and low in efficiency, the exposed metal part cannot be completely covered in the green glue coating operation process, and the operation still has great potential safety hazards caused by failure.

Disclosure of Invention

The invention provides the insulating glue for the lithium ion battery, which can well and compactly cover irregular metal exposed parts, is simple to operate and has excellent insulating effect.

In order to achieve the purpose, the invention is realized by the following technical scheme: the insulating glue for the lithium ion battery is prepared from the following raw materials in parts by weight: 15-30 parts of epoxy resin, 6-10 parts of organic silicon resin, 10-14 parts of epoxy resin curing agent, 3-5 parts of nitrile rubber, 4-8 parts of triethanolamine and 10-30 parts of inorganic filler.

Has the advantages that: the invention can be easily sprayed, brushed or dipped, has the characteristics of moisture resistance, acid resistance, friction resistance, corrosion resistance and the like, can be used under various weather conditions, and has good sealing and insulating properties on the coated part.
