Abstract

The present invention provides an electrolyte having a cement-based structure and a preparation method therefor. Raw materials for the electrolyte having the cement-based structure include an inorganic gel material, a polymer monomer, polyacrylic acid, an initiator, and modified aluminosilicate zeolite, wherein the modified aluminosilicate zeolite is prepared by soaking aluminosilicate zeolite in a solution of a silicone-modified polyacrylate containing OH functional groups, taking out the aluminosilicate zeolite, performing heat treatment, and then soaking the aluminosilicate zeolite in a lithium salt solution, wherein the polymer monomer is a mixture of acrylamide and a long-carbon-chain alkyl acrylate hydrophobic monomer. In the present invention, by means of a synergistic hydrophobic effect of the modified aluminosilicate zeolite and a multi-component-copolymerized modified polyacrylamide, the dispersion of the polymer network in a cement paste is promoted, facilitating the formation of a uniformly distributed polymer network and the improvement of the ionic conductivity of the electrolyte; in addition, the modified aluminosilicate zeolite adsorbs a certain amount of a lithium salt, thereby contributing to the improvement of a discharge window of the electrolyte having the cement-based structure.
