▎ 摘　　要

NOVELTY - Layered inorganic nanosheet-graphene composite comprises a first inorganic nanosheet, a second inorganic nanosheet, and a layered structure formed by re-laminating graphene. USE - The composite is useful in sodium ion battery (claimed). ADVANTAGE - The composite can be easily prepared, improves capacity and cycle stability of sodium ion battery, and prevents graphene from being reallocated during battery charge/discharge process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for producing layered inorganic nanosheet-graphene composite, comprising (a) peeling the first inorganic nanosheet and the second inorganic nanosheet, (b) mixing the peeled first inorganic nanosheet, the peeled second inorganic nanosheet and graphene, and (c) obtaining the layered inorganic nanosheet-graphene composite on which the peeled first inorganic nanosheet, the peeled second inorganic nanosheet and graphene are re-laminated by adding cation-containing solution into the obtained mixture.
