▎ 摘　　要

NOVELTY - Preparing a hybrid composite comprises mixing alkali ion precursor solution into the bulk material powder of a first nanosheet, intercalating alkali ions between the layers of the three-dimensional bulk material of the first nanosheet having multi-layer structure by treating the mixture with sonication, injecting water into the mixture after sonication, applying a surfactant to the second nanosheet, mixing first nanosheet mixture to which water is applied and the second nanosheet to which the surfactant is applied, and bonding using electrostatic attraction, and heat-treating the mixture and removing the surfactant to obtain a hybrid complex. USE - The composite is useful for preparing anode active material for lithium-ion battery (claimed). ADVANTAGE - The composite: improves structural stability, charge/discharge capacity, coulomb efficiency and cycle characteristics. The method: is fast and increases productivity; does not required high temperature treatment. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) hybrid composite; (2) anode active material comprising a hybrid composite; and (3) lithium-ion battery comprising anode, a separator interposed between the anode and the cathode, and electrolyte.
