WATER ACTIVATED BATTERY

A battery includes a battery casing defining a chamber therein, and an electrolyte powder disposed in the chamber. The electrolyte powder is configured to surround a zinc material that is separated from the electrolyte powder by a permeable separator sheet. The battery also includes a conductive member having a first end configured for electrical communication with an anode terminal of the battery, and, a second end configured for electrical communication with the zinc material. A conductive layer is also disposed between an inner surface of the casing and the electrolyte powder, the conductive layer being configured for electrical communication with a cathode terminal of the battery. There is also a liquid release mechanism configured for allowing release of a liquid in the chamber to activate an ion flow between the electrolyte powder and the zinc material via the permeable separator sheet.
