Solution permeation preparation method of polymer/molecular sieve solid electrolyte

The invention relates to the technical field of polymer/molecular sieve composite materials and solid-state battery electrolytes, and discloses a polymer/molecular sieve solid-state electrolyte as well as a preparation method and application thereof. A molecular sieve is used as a matrix, and polymers and molecules are introduced in a polymer solution permeation manner to fill sieve pore channels to form an inorganic material-polymer interface layer; and gaps among particles in the matrix are filled with the polymer, so that interface contact in the solid electrolyte is improved, and an ion-conducting polymer/molecular sieve electrolyte membrane continuum is formed. The polymer/molecular sieve solid electrolyte obtained by the preparation method has the characteristics of an inorganic material and a polymer, has excellent ionic conductivity, has good compatibility with positive and negative electrodes, and has strong metal dendritic crystal pressing capacity. The energy storage battery taking the polymer/mole
