A battery (10) is disclosed having a negative or anodic half cell (12) and a cathodic or positive half cell (13). The positive and negative half cells are encased within a fabric within a non-conductive housing (14). The housing includes holes (18) which allow the passage of ambient air. The anodic material (20) is preferably a transition metal bronze such as Na0.9W0.75Ti0.25O3. The positive half cell is made of a cathodic material (25) in the form of powder which is encased a fabric (26). The cathodic material is preferably Na0.9W0.75P0.25O3.325. The battery also includes an electrical conductor (31) in electrical contact with the positive half cell and the negative half cell. The electrical conductor includes a switch (35) which may be opened and closed to couple the half cells together to produce an electric current through a load (36).
