Composite electrolyte structure of quasi-solid-state battery

The utility model provides a composite electrolyte structure of a quasi-solid-state battery, which comprises a high-porosity electronic insulation polyimide film which is an electronic insulation base material carrier with high porosity and is provided with a plurality of pores, and an electrolyte layer which is arranged on the polyimide film, the colloidal electrolyte is filled in the plurality of pores of the polyimide film, so that the polyimide film forms a quasi-solid electrolyte of the quasi-solid battery and serves as a carrier for storing the electrolyte; therefore, the arrangement of isolating membranes between the quasi-solid electrolyte and the positive and negative electrodes can be omitted, the defect of leakage of the electrolyte of the battery is avoided, the safety of the battery can be greatly improved, the contact between the positive and negative electrodes is good, the resistance is small, the energy consumption during charging and discharging can be reduced, the charging and discharging e
