Abstract

The invention discloses a preparation method of a flexible solid-state battery, comprising the following steps: providing a positive electrode of the flexible solid-state battery; providing a negativeelectrode of the flexible solid-state battery; drying the positive electrode of the flexible solid-state battery and the negative electrode of the flexible solid-state battery; preparing a ultra-thinflexible solid electrolyte membrane by chemical vapor deposition; placing a first encapsulation film, the positive electrode of the flexible solid-state battery, the ultra-thin flexible solid-state electrolyte membrane, the negative electrode of the flexible solid-state battery, and a second encapsulation film sequentially to form a first laminated structure, and encapsulating the laminated structure. The flexible solid-state battery prepared by the method has certain tensile lightness and torsional strength, good electronic insulation and ion conductivity, and can be conveniently combined with wearable products, thereby overcoming the shortcomings that the traditional liquid electrolyte system lithium ion battery cannot meet the above requirements.

Description

technical field [0001] The present application relates to the technical field of solar energy, in particular to a flexible solid-state battery and a preparation method thereof. Background technique [0002] The practical application of batteries in our lives is playing an increasingly important role, including consumer electronics, electric vehicles, large, medium and small energy storage systems, etc., and their power supplies are all types of batteries, among which the rapidly developing lithium Mainly ion batteries. However, the current commercial lithium-ion batteries have gradually failed to meet the needs of rapid product development, such as higher energy density, longer cycle life, and safer and cheaper. At the same time, with people's pursuit of individuality and self-expression, as well as the popularity of smart mobile devices such as intelligence and networking, smart wearables are favored, such as smart bracelets, glasses, watches, shoes and hats, etc., while ...
