Electrically restorable rechargeable battery, and methods of manufacture and methods of operating the battery

A battery system including: a lithium-ion cell including a positive electrode including a first metal oxide, an electrolyte, and a negative electrode including a second metal oxide having an electrochemical redox potential of 0.5 volt to 3 volts versus lithium; and an electrical circuit including a switchable component connecting the positive electrode and the negative electrode, wherein the switchable component provides a shunt between the positive electrode and the negative electrode in a first switch position, and wherein the electrical circuit is configured to provide a voltage of 0.1 volt or less between the positive electrode and the negative electrode when the switchable component is in the first switch position.
