Gel polymer lithium ion electrolyte and battery containing electrolyte

Current Patent Assignee: GANZHOU SHILEI NEW ENERGY TECH - CN115832422, 2023, A
Patent Family Members: CN115832422 A



Abstract

The invention relates to the technical field of lithium batteries, in particular to a gel polymer lithium ion electrolyte and a battery containing the electrolyte. The preparation method comprises the following steps: S1, in an environment filled with protective gas, dissolving polyvinylidene fluoride hexafluoropropylene in a first organic solvent, uniformly stirring and mixing to obtain a mixed solution, taking the mixed solution as an electrostatic spinning solution, and obtaining a polymer diaphragm matrix by adopting an electrostatic spinning method; s2, in an environment full of protective gas, adding lithium salt into a second organic solvent, uniformly mixing, then adding a flame-retardant additive and a film-forming additive, and stirring to obtain electrolyte; and S3, soaking the polymer diaphragm substrate in the electrolyte for 4-24 hours, and taking out the polymer diaphragm substrate to obtain the gel polymer lithium ion electrolyte. The use safety performance is high, and the service life is long. The battery containing the gel polymer lithium ion electrolyte is also high in use safety performance and long in service life.


Super-long salt fog resistant waterborne graphene modified epoxy primer heavy anti-corrosion coating and preparation method thereof

Current Patent Assignee: HEBEI YOUYANG TIMES ENVIRONMENTAL PROTECTION TECH - CN115820073, 2023, A
Patent Family Members: CN115820073 A



Abstract

The invention relates to the technical field of coating technologies, and provides a super-long salt fog resistant waterborne graphene modified epoxy primer heavy anti-corrosion coating and a preparation method thereof.The super-long salt fog resistant waterborne graphene modified epoxy primer heavy anti-corrosion coating comprises a component A and a component B. The component A comprises, by weight, 50-60 parts of waterborne epoxy resin emulsion, 1-2 parts of graphene oxide, 0.11-0.18 part of a flash rust inhibitor and 10-15 parts of water; the component B is prepared from the following components in parts by weight: 12 to 18 parts of a curing agent, 15 to 19 parts of N-methyl pyrrolidone, 1.2 to 1.5 parts of an anti-settling agent, 2 to 3 parts of a dispersing agent, 3.6 to 4.3 parts of a coalescing agent, 100 to 150 parts of zinc powder, 5 to 10 parts of mica powder and 10 to 15 parts of talcum powder; the graphene oxide is modified graphene oxide. According to the technical scheme, the problem that in the prior art, graphene is prone to agglomeration, and consequently the corrosion resistance of the coating is reduced is solved.
