Abstract

An environment-friendly battery conductive coating material is composed of the following raw materials in parts by weight: 40-60 parts of a base material, 15-25 parts of a conductive additive, 10-18 parts of an inorganic filler and 8-15 parts of a modification additive. The environmentally friendly battery conductive coating material provided by the present invention has good adhesion and low contact resistance through reasonable raw material ratio and a large number of experiments, which can effectively reduce the amount of adhesive and improve the environmental protection of battery manufacturing. property; the conductive coating of the present invention does not contain highly toxic toluene and xylene, and has better sealing effect.

Description

technical field [0001] The invention relates to the technical field of battery processing materials, in particular to an environment-friendly conductive coating material for batteries. Background technique [0002] With the development of lithium iron phosphate battery, because it has the possibility of becoming an automobile power battery, it has been continuously concerned by all parties. Due to its own characteristics, the rate type lithium iron phosphate material is developing towards nanometerization, which makes its processing performance change. Poor, in order to improve its processing performance, reduce the electrode sheet resistance or battery internal resistance, conductive coating technology began to be applied on a large scale, and thus developed to be more specialized, and extended to other related industries. [0003] Conductive coating is also called pre-coating. In the lithium battery industry, it usually refers to a layer of conductive coating coated on the...
