Abstract
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.
