Water activated batteries based on protected lithium electrodes

Abstract

A high energy density lithium water-activated battery having a compact, readily manufacturable, and scalable electrode stack structure has enhanced tolerance to stress conditions such as shock and vibration, which may be experienced during shipping, transport and/or deployment into a waterbody (e.g., an ocean). A Li seawater battery pack can provide power to a marine device deployed in or on the surface of a waterbody via one or more seawater battery modules and a power circuit module having one or more input terminals for receiving battery voltages from the one or more battery modules. The power module conditions each of the battery voltages and consolidates these into a single operating output voltage, and the cathode electrodes from each of the battery modules share a common electrolyte comprising water from the waterbody.
