Abstract
A method of forming an LMNO cathode with electrolytic manganese dioxide includes dissolving metallic manganese in acid to create a dissolved manganese solution, disposing the solution within an electrolytic cell including an electrolytic cell anode and an electrolytic cell cathode, and applying a current between the cell anode and the cell cathode to the solution. Applying the current forms an MnOdeposit upon the cell anode. The method further includes harvesting the deposit, creating a manganese precursor by neutralizing the deposit and grinding the deposit to form an MnOpowder, and mixing the manganese precursor with a nickel precursor and a lithium precursor to create a mixture. The method further includes calcining the mixture to create an LMNO powder and coating a current collector with the LMNO powder to thereby form the LMNO cathode. The method may include testing the cathode electrode in an electrochemical pouch format cell.
