▎ 摘　　要

NOVELTY - Hydrophobic sodium-ion battery anode material comprises sodium ion battery anode material and hydrophobic composite layer formed on the surface of sodium ion battery anode material, where the sodium ion battery anode material is a layered metal oxide, and the general formula is NaxMO2+y, where M is at least one transition metals, x = 0.5-1, y = -0.1-0.1, and each element satisfies charge balance, and the hydrophobic composite comprises hydrophobic agglomerant and a carbon material, and the hydrophobic agglomerant is a fluorine-containing polymer. USE - Used as hydrophobic sodium-ion battery anode material. ADVANTAGE - The material: has excellent water resistance; and improves the stability and electrochemical performance of the layered oxide material after homogenizing. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: preparing the hydrophobic sodium-ion battery anode material; a sodium ion battery anode; and a sodium ion battery.
