Abstract

The battery includes a cathode configured to employ water as a cathode active material. The battery also includes an anode having an anode active material. An electrolyte activates the anode and the cathode. The electrolyte includes a lithium ion conductive glass-ceramic supported on a porous support such that the support provides mechanical support to the electrolyte. The electrolyte is substantially impermeable to water and acts as a barrier between the water and the anode. The anode active material may be contained in a bellows section of the case of the battery, such that a decrease in volume of the anode active material during discharge of the battery causes the bellows section of the case to contract.
