Abstract
In at least one embodiment, a lithium-ion battery is provided comprising a positive electrode, a negative electrode, an electrolyte, and a separator situated between the electrodes. At least one of the electrodes may include a proton absorbing material. The proton absorbing material may be an atomic intermetallic material including a proton absorbed state. The proton absorbing material may react with protons in the electrolyte to reduce moisture formation and cathode degradation in the battery. The proton absorbing material may absorb at least 0.5 wt. % hydrogen and may be present in the anode and/or cathode in an amount from 0.01 to 5 wt. %.
