An anode material is based on lithium-titanium spinel that contains doping components, chromium and vanadium, in equivalent quantities, of the chemical formula LiTi(CrV)O, where x is the deviation from stoichiometry within the limits 0.02&#x3c;x&#x3c;0.5, and y is the stoichiometric coefficient within the limits 0&#x3c;y&#x3c;0.1. Producing the anode material involves preparation of a mixture of the initial components that contain lithium and titanium and sources of dopants, chromium and vanadium, by means of homogenization and pulverization, which is carried out until particles no greater than 0.5 &#x3bc;m in size are obtained, with subsequent stepwise heat treatment of the prepared mixture in a controlled atmosphere of inert argon and reducing acetylene, at a ratio of the gases in the argon-acetylene stream from 999:1 to 750:250, respectively.

Lithium-based materials and methods of forming the same. In at least one embodiment of a method of forming a lithium-based material of the present disclosure, the method comprises the steps of combining a first quantity of a first lithium-based component and a second quantity of a second lithium-based component with a titanium-based component to form a mixture, the first lithium-based component having a first melting point and the second lithium-based component having a second melting point higher than the first melting point of the first lithium-based component, and heating the mixture to a first temperature above the first melting point but below the second melting point for a period of time to form a resultant end product.

Lithium-based materials and methods of forming the same

A lithium titanate is formed by mixing lithium carbonate powder or lithium hydroxide powder with titanium oxide followed by preparing a mixed slurry of titanium compound powder and a solution containing lithium, followed by depositing a lithium compound by spray-drying.

Lithium titanate and method of forming the same

A lithium titanate has the following formula:LiTiOwherein x is greater than 0. The lithium titanate is formed by providing a mixture of titanium dioxide and a lithium-based component. The mixture is sintered in a gaseous atmosphere comprising a reducing agent to form the lithium titanate having the above formula. A lithium-based cell includes an electrolyte, an anode, and a cathode, with at least one of the anode and the cathode comprising the lithium titanate having the above formula. The lithium titanate is deficient of oxygen, which increases electronic conductivity of the lithium titanate by at least three orders over electronic conductivity of a stoichiometric lithium titanate, while avoiding loss of reversible electric power-generating capacity that typically occurs when doping is used to replace titanium in the lithium titanate with atoms that provide higher electronic conductivity.
