Abstract
An electrochemical energy storage device includes a cathode, an anode, and an electrolyte disposed between the cathode and the anode. The anode includes a capacitive material as a majority component, and further includes an electrochemically active material as a minority component, such that an operating potential of the anode is configured according to a reaction potential of the electrochemically active material.
