Abstract

The invention discloses the application of a multifunctional organic gel in lithium ion batteries. The raw materials for the preparation of the multifunctional organic gel include: solvents, monomers, crosslinking agents, electrolyte salts and initiators. The solvent The volume ratio of the monomer to the monomer is 1:5 to 5:1; the molar ratio of the crosslinking agent to the monomer is 0.05% to 10%; the molar ratio of the initiator to the monomer is 0.1% to 10%, and the electrolyte The concentration of the salt in the mixed solution of all raw materials is 0.1mol / L-5mol / L. Since the conductivity of the multifunctional organic gel is close to the level of the electrolyte, the present invention uses the multifunctional organic gel for the preparation of lithium-ion batteries, and the batteries can be used normally.

Description

technical field [0001] The invention relates to the field of ion conductors, in particular to the application of a multifunctional organic gel in lithium ion batteries. Background technique [0002] Flexible electronic devices have attracted worldwide attention and developed rapidly in recent years. With the increasing demand for flexible wearable devices and soft machines, some high-performance ionic conductors with unique functions are gradually favored by people. Different from electronic conductors, ionic conductors use ions as charge carriers to transmit signals, realizing many functions that are difficult for electronic conductors, thus making various modern technologies possible, such as fuel cells, alkaline batteries, electrochemical transistors, sensors, etc. Hydrogel is the most widely studied ion conductor at this stage, with good transparency, flexibility and conductivity, easy to obtain raw materials, and low price. However, the volatility of water is strong, i...
