Abstract
Materials, designs, methods of manufacture, and devices are provided for an anode material for a rechargeable lithium-ion battery. For example, an anode material may include Li3±xV2±yO5±z, wherein 0≤x≤7, 0≤y≤1, and z may be based on the charge resulting from Li3±x and V2±y. Also, a cell can include a lithiated anode material. The lithiated anode material may include Li3±xV2±y O5±z. The lithiated anode material may be casted on a first substrate to form a lithiated anode, having a separator stacked on the lithiated anode. The separator may include electrolytes. A cathode can be stacked on the separator. The cathode being formed by casting a cathode material on a second substrate.
Claims8
An anode material for use in an anode of a lithium-ion battery, wherein the anode material comprises Li3+xV2±yO5±z, wherein 0<x≤2, 0≤y≤1, and z is based on the charge resulting from Li3+x and V2±y, wherein the Li3+xV2±yO5±z is an omega structure, and wherein the omega structure is a disordered rocksalt structure in the Fm3m space group, and wherein the anode material is characterized by a voltage plateau from about 0 V to about 1 V.
