Cement-based lithium battery and preparation method thereof

The invention relates to the technical field of batteries, and particularly discloses a cement-based lithium battery and a preparation method thereof. Functional materials commonly used in a lithium battery, including lithium cobalt oxide, lithium iron phosphate, polyoxyethylene and the like, are combined with a cement material, iron powder is used for preparing an electrolyte of the battery for the first time, and polyvinylidene fluoride and styrene butadiene rubber are used for preparing a bonding layer of the battery for the first time; the preparation method of the novel cement-based lithium battery capable of being charged and discharged repeatedly is formed. The cement-based lithium battery prepared by the invention is high in energy density, long in service life and high in compressive strength retention rate, can be directly applied to each part of a civil and constructional engineering structure, enriches the functions of a cement material, can be better applied to the field of constructional enginee
