Abstract

The invention relates to a composite binding agent. The composite binding agent comprises a binding agent and a dispersion medium, wherein the binding agent is dispersed in the dispersion medium to form a solution and comprises resin, a fixed agent and gelatin, and the dispersion medium is an organic solvent. The binding agent is good in cohesiveness and low in cost and is safe, a favorable conductive network can be helped to be built between an active substance and a conductive agent, the binding agent stably exists in the organic solvent, the energy density and the power density of a batterycapacitor can be effectively improved.

Description

technical field [0001] The invention relates to an adhesive, in particular to a composite adhesive. Background technique [0002] Lithium-ion hybrid supercapacitors have the dual characteristics of lithium-ion batteries and supercapacitors. It has higher energy density than conventional supercapacitors, higher power density than lithium-ion batteries, longer life, and higher safety. It is expected to be used in electric vehicles and electrical equipment. , military and aerospace facilities and other high-energy and high-power electronic products. It is very necessary to find a safe, cheap and efficient binder. Contents of the invention [0003] In order to solve the problems of insufficient bonding strength of the binder in the prior art and certain toxicity of the battery binder, the invention provides a novel composite binder. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a composite binder, comprising a bind...
