Title:
HYBRID SOLID-LIQUID ELECTROLYTE LITHIUM STORAGE BATTERY
Document Type and Number:
WIPO Patent Application WO/2020/181681
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of solid-state lithium storage batteries, and particularly discloses a hybrid solid-liquid electrolyte lithium storage battery. The lithium storage battery comprises a positive electrode sheet, a negative electrode sheet, and a composite solid-state electrolyte sheet arranged between the positive electrode sheet and the negative electrode sheet, wherein the composite solid-state electrolyte sheet comprises a solid-state electrolyte core layer and adhesive buffer layers arranged on two sides of the solid-state electrolyte core layer; and the solid-state electrolyte core layer is mainly formed by means of mixing a core layer inorganic solid-state electrolyte, an electrolyte polymer and an electrolyte additive, and each adhesive buffer layer is mainly formed by means of mixing an adhesive buffer layer inorganic solid-state electrolyte, an adhesive buffer layer lithium salt and an adhesive buffer layer additive. During the preparation of the lithium storage battery of the present invention, co-extrusion technology and rolling technology are combined, one-step processing and molding are achieved, the lithium storage battery has the characteristics of a high production efficiency and simple and convenient operation, and lithium storage batteries manufactured thereby have a relatively high electric cycle performance and safety performance.
