  • Publication number: 20230282804
    Abstract: A lithium-ion battery includes an electrode with a plurality of channels formed at least partially through its thickness. Each channel has a diameter in a range from 5 ?m to 100 ?m and/or is spaced apart from another channel by a distance in a range from 10 ?m to 200 ?m as measured between centerlines of the channels. The electrode may be an anode and includes carbonaceous material such as graphite and/or additional electrochemically active lithium host materials. The battery can be charged at a C-rate greater than 2 C.

  • Patent number: 11626583
    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.
