▎ 摘　　要

NOVELTY - Anode material comprises an electrically conducting 3-dimensional matrix, and chemical bonding groups, where each of the chemical bonding groups are chemically bonded to a surface of the electrically conducting 3-dimensional matrix. USE - The anode material is used for anode for device, preferably electrochemical device such as battery, supercapacitor, fuel cell, electrolyzer, or electrolytic cell, where the battery is ion-conducting battery such as aluminum-ion conducting battery, zinc-ion conducting battery, lithium-ion conducting battery, sodium-ion conducting battery, calcium-ion conducting battery, or magnesium-ion conducting battery (all claimed). ADVANTAGE - None given. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: an anode comprising anode material(s); a method for making an electrode material, which involves (i) functionalizing an electrically conducting 3-dimensional matrix, or (ii) providing an electrically conducting 3-dimensional matrix comprising first chemical bonding groups chemically bonded to a surface of the electrically conducting 3-dimensional matrix, where each of the chemical bonding groups are chemically bonded to a surface of the electrically conducting 3-dimensional matrix, and functionalizing the electrically conducting 3-dimensional matrix comprising first chemical bonding groups with a material comprising 3-dimensional second chemical bonding groups to form the electrode material; and a device comprising the anode(s).
