Lithium ion electrochemistry comprising: a cathode comprising an electrochemically active metal oxide coating on a first current collector; an electrolyte; and an anode comprising an electrochemically active alloy coating on a second current collector. Serve cells. Both the anode and cathode have a reversible capacity in excess of 4.5 mAh / cm 2 per coated surface. The metal oxide coating typically comprises cobalt, manganese, nickel, or combinations thereof. The reversible capacity of the cathode is within 15% of the reversible capacity of the anode.
