▎ 摘  要

NOVELTY - The anode pole piece comprises a porous anode framework (1), a lithium-philic substance (2) with gradient distribution in the porous framework concentration, and a current collector (3). The concentration of the lithium-philic substance is gradually reduced from the current collector to the direction of the surface of the framework. The lithium-philic substance has a metal, oxide, or a specific functional group-containing substance. The metal includes silver, aluminum, gold, barium, calcium, indium, platinum, silicon, tin, or zinc. The oxide includes titanium dioxide, silicon dioxide, and/or zinc oxide. The functional group has hydroxyl, ester groups, carboxyl groups, or amino groups. USE - Anode pole piece for the lithium-ion battery used in an electronic device (all claimed), such as an electric automobile, and mobile electronic devices. ADVANTAGE - The anode pole piece controls the deposition direction of the lithium, so that the lithium metal is uniform and controllable deposition. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a lithium-ion battery. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an anode pole piece for the lithium-ion battery used in an electronic device. Porous anode framework (1) Lithium-philic substance (2) Current collector (3)
