▎ 摘  要

NOVELTY - Double-layer coating modified lithium ion battery anode material powder comprises a anode material substrate. A first coating layer covered on the surface of anode material substrate. A second coating layer covered on the surface of the first layer coating layer, where the first cladding layer is a carbon nanosphere coating layer, and the second coating layer is a metal oxide coating. USE - Used as double-layer coating modified lithium ion battery anode material powder. ADVANTAGE - The cathode material powder: solves the problem of bad conductivity of single-layer metal oxide coating; prevents a small amount of hydrofluoric acid in the electrolyte from corroding the anode material; has high multiplying power performance, high specific capacity and good cycle performance. The method: is simple, is easy to operate and suitable for large-scale industrial production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing double-layer coating modified lithium ion battery anode material powder.
