Abstract

The invention relates to a preparation method and application of a composite solid electrolyte based on a metal organic framework / ionic liquid. The preparation method comprises the following steps: preparing a novel composite filler based on a metal organic framework / ionic liquid, uniformly stirring the composite filler, a polymer matrix and a lithium salt in an organic solvent, pouring the mixture on a template, and carrying out blade coating to form a film, thereby obtaining the composite solid electrolyte. The preparation method has the advantages that the ionic conductivity of the solid-state electrolyte can be effectively improved, and the lithium dendritic crystal inhibition capability is improved; and in an assembled all-solid-state lithium battery, relatively good long cycle performance and rate capability are shown, wide production and application of the all-solid-state battery are facilitated, and the all-solid-state battery has a wide application prospect.

Description

technical field

[0001] The invention belongs to the field of all-solid-state lithium batteries, in particular to a method for preparing a metal-organic framework / ionic liquid composite solid-state electrolyte. Background technique

[0002] Lithium-ion batteries have received widespread attention due to their high energy density, long cycle life, low self-discharge rate, no memory effect, fast charge and discharge, and environmental friendliness. However, traditional lithium-ion batteries use liquid electrolytes, which have Volatile, flammable, explosive and other shortcomings will cause many safety hazards. The use of all-solid-state lithium batteries can avoid safety issues and can effectively inhibit the growth of lithium dendrites. Therefore, all-solid-state lithium batteries can use metal lithium instead of traditional graphite materials to achieve physical series connection inside the battery to increase the voltage of the cells and increase the energy of the battery. ...
