Embodiment 1

[0033] Put 30g of metal ion or non-metal ion functional graphene, 3000g of polyurethane, 1g of chelating agent and appropriate amount of borax in an ultrasonic disperser for dispersion. The dispersion process is carried out under negative pressure conditions, and the ultrasonic power is 1 Disperse for 1h under the condition of -5kW.

Embodiment 2

[0035] Put 2500g of metal ion or non-metal ion functional graphene, 5000g of polyurethane, 1g of chelating agent and appropriate amount of borax in an ultrasonic disperser for dispersion. The dispersion process is carried out under negative pressure conditions, and the ultrasonic power is 1 Disperse for 1h under the condition of -5kW.

[0036] If functional graphene with ion intercalation is added, the conductivity and ion exchange performance can be further improved. For example, the addition of boron and iodine ion intercalation graphene can further strengthen the performance of gel electrolyte in lithium batteries.

Abstract

The invention discloses a graphene solid gel electrolyte and a synthesis process thereof. The electrolyte comprises a graphene material, a waterborne polyurethane material, a chelating agent and borax. Graphene is added with waterborne polyurethane material and then achieves balanced dispersion, by adding the chelating agent, molecules of the graphene and the waterborne polyurethane material are firmly linked, and the stable state is kept; the borax is added, the viscosity of the waterborne polyurethane material is increased, and the gel state is reached. The graphene solid gel electrolyte hasthe liquid glue characteristic of the gel, by means of combination with the graphene, the electrolyte has the good conductive and ion exchange efficiency, and the function of the electrolyte is achieved. By means of the liquid viscosity of the gel, the positive electrode and negative electrode material surface contact of a battery can be enhanced, and the electrolyte is specially suitable for cooperating with a rough contact surface. In high-power battery application, high heat transfer of the graphene can greatly improve the whole heat dissipation efficiency of the battery, and the problem that the battery is too hot is reduced.

Description

technical field [0001] The invention relates to the technical field of graphene application, in particular to a graphene solid gel electrolyte and a synthesis process thereof. Background technique [0002] The application of graphene has attracted the attention of the whole world, but the research on graphene is still in its infancy. Graphene is a very unique two-dimensional new material. However, the application of this new material is mainly in the addition of materials. The development of deeper and functional materials is the direction of scientific and technological progress. This requires that raw materials must be materials with functional properties. The material made from the original graphene is called N-type graphene, which means that the current graphene material as an additive material is called N-type graphene without its own characteristics and without ions. The meaning of refers to: non-ionic graphene or neutral graphene without ionic properties. It is nec...
