Title: 3-D composite anodes for Li-ion batteries with high capacity and fast charging capability

Abstract

An anode for a lithium ion battery is disclosed includes a first major face, a second major face that, together with the first major face, defines a thickness of the anode, and at least one carbonaceous electrochemically active lithium host material distributed between the first and second major faces of the anode. The at least one carbonaceous electrochemically active lithium host material is selected from the group consisting of graphite, hard carbon, or a blend of graphite and hard carbon. The anode additionally defines a plurality of vertical channels extending at least partially through the thickness of the anode. A lithium-ion batter that includes the disclosed anode and a method of charging a lithium-ion battery that includes the disclosed anode are also disclosed.
