NOVELTY - A graphene-containing electrolyte preparing method involves centrifugal separating the raw material of graphene oxide, taking the upper layer liquid, and drying at a low temperature to obtain a graphene oxide powder after centrifugation, drying the centrifugally graphene oxide powder under vacuum to form a crude product, mixing the crude product with an organic solvent, adding an additive, heating and stirring uniformly, filtering while hot and drying the filtrate under vacuum to obtain a finished product Q, using the product Q as one of the components, disposing the graphene electrolyte, where the graphene electrolyte is composed of 85-95 wt.% product Q, 0.1-3 wt.% auxiliary agent and 2-15 wt.% lithium salt, product Q is composed of 10-20 wt.% centrifuged graphene powder, 1-5 wt.% additive and balance organic solvent. USE - Method for preparing graphene-containing electrolyte. ADVANTAGE - The electrolyte has improved stability.
