Northwestern team develops way to stabilize high capacity Li4Mn2O5 cathode; doping with vanadium or chromium

Green Car Congress

Lithium-ion batteries shuttle lithium ions back and forth between the anode and the cathode. The transition metal, typically cobalt, effectively stores and releases electrical energy when lithium ions move from the anode to the cathode and back. An open-access paper on their work is published in the journal Science Advances.
