NOVELTY - Method for preparing fast lithium ion transport material involves mixing a graphene oxide solution, an organic lithium salt, an activator and a condensing agent and reacting to obtain product, where the organic lithium salt is chosen from adenosine-5'-diphosphate trilithium salt, adenosine 5-O-thiomonophosphate dilithium salt and guanosine 5-O-(3-thiotriphosphate) tetralithium salt. USE - The method is useful for preparing fast lithium ion transport material which is used in solid electrolyte and protective coating for lithium metal batteries, and in lithium ion battery (all claimed). ADVANTAGE - The method prepares fast lithium ion transport material which is reduced required addition amount and has both good mechanical properties and excellent lithium ion transport capability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) solid electrolyte for lithium metal batteries comprising the fast lithium ion transport material; and (2) protective coating on the surface of a metal lithium negative electrode comprising the fast lithium ion transport material.
