It has been discovered that improved disordered rocksalts comprise of Mn are made by method comprising mixing a lithium compound with a metal precursor compound comprised of Mn having an oxidation state of 2 to form a mixture and heating the mixture to a temperature to form a disordered rocksalt structure. The method may realize improved cycle life with altered metal and oxygen redox of the disordered rocksalt.

Disordered rocksalt cathode material and method of making it

A disordered rocksalt (DRS) having improved characteristic has a cation comprised of lithium and one other metal and an anion comprised of oxygen and fluorine, and one or more of phosphorous, sulfur, and nitrogen. The substitution of one or more of P, S, and N on the oxygen anion site may realize improved cycle life of the battery and/or may be useful to make safer batteries.

Disordered rocksalt material and method of forming it

A cathode includes a disordered rocksalt phase material and a coating layer disposed on a surface of the disordered rocksalt phase material. The coating layer may include one or more of an oxide, a phosphate, a phosphide, or a fluoride.

Cathode with coated disordered rocksalt material

A method for forming a cathode includes milling a suspension of precursors via a micromedia mill to form a mixture of primary particles in the suspension. The precursors include one or more metal compounds. The method includes spray drying the suspension after the milling to form secondary particles. The secondary particles are agglomerations of the primary particles. The method also includes annealing the secondary particles to form a disordered rocksalt powder.
