Abstract

The invention relates to an ionic liquid compound, a preparation method thereof, an ionic liquid polymer, use of the ionic liquid polymer and polymer solid electrolyte containing the ionic liquid polymer and particularly provides an ionic liquid compound with the structure presented by a formula (1) (shown in the description), a preparation method of the ionic liquid compound, an ionic liquid polymer with the structure represented by a formula (20) (shown in the description) and a preparation method of the ionic liquid polymer. Anion centers of the ionic liquid compound and the ionic liquid polymer are perfluorsulfimide ions with relatively weak coordination capacity, so that the binding capacity of the anion centers to Li<+> is reduced, and the specific conductance and Li<+> transferencenumber of the polymer solid electrolyte containing the containing ionic liquid polymer are increased; and the ionic liquid polymer is compounded with lithium salt so as to form the polymer solid electrolyte containing an ionic liquid-polyion liquid compound, and the ionic liquid-polyion liquid compound has a micro-liquid phase structure, so that the specific conductance and Li<+> transference number of the electrolytecan be further increased.

Description

technical field [0001] The disclosure relates to the field of polymer electrolytes, in particular, to an ionic liquid compound and a preparation method, an ionic liquid polymer, its use, and a polymer solid state electrolyte containing the polymer. Background technique [0002] The polymer electrolyte is composed of polymer and lithium salt. The polymer lithium-ion battery can avoid the defects of liquid leakage and explosion in the organic liquid electrolyte in the traditional lithium-ion battery during use. It has plasticity, flexibility, small size and safety. It has the advantages of good performance and large-scale industrial production, so it has attracted widespread attention. However, the room temperature conductivity of existing polymer electrolytes is low, which cannot meet the application requirements. Ionic liquids are usually liquid at room temperature, and have the characteristics of low viscosity, non-volatile, non-combustible, low toxicity, high room tempera...
