Ceramic coated polyolefin diaphragm slurry for lithium battery and preparation method of ceramic coated polyolefin diaphragm slurry
The invention discloses ceramic coated polyolefin diaphragm slurry for a lithium battery and a preparation method of the ceramic coated polyolefin diaphragm slurry, and belongs to the technical field of diaphragm coating slurry processing. The ceramic coating polyolefin diaphragm slurry is used for solving the technical problem that the ionic conductivity, the lyophilic property and the thermal dimension temperature property of a polyolefin diaphragm in the prior art need to be further improved, and is prepared from a binding material, N-methyl pyrrolidone, modified aluminum oxide, a dispersing agent and a stabilizing agent according to the weight ratio of 3: 85: 12: 1: 1. The binding material is prepared by carrying out high-temperature condensation on 4, 4 '-diaminodiphenyl sulfone and 4, 4'-oxydiphthalic anhydride in a mixed system of xylene and N-methyl pyrrolidone. According to the invention, the lyophilic performance and ionic conductivity of the polyolefin diaphragm and electrolyte are effectively improved, and the thermal stability and liquid absorption rate of the polyolefin diaphragm are also improved.
