A particulate composite fuel of metal preferably of aluminum for a portable heater. The fuel reacts with oxygen in the air, producing heat. The composite fuel may also be flaked aluminum or iron nanopowder. A portable heater having a fuel mass, at least one thermal conductive member, and at least one insulating member. The heater transfers the heat of the oxidation of the metal particulate fuel to a desired mass to be heated, typically a food item. The multilayered heater also acts as a buffer absorbing released heat and releasing the heat to the desired mass at a rate slower than the absorbing.

A battery cell, such as a cylindrical alkaline cell, is disclosed having significantly improved capacity utilization at high discharge rates while maintaining much of the energy content and other feature advantages of typical cylindrical alkaline cells, by implementing a novel cell construction that produces increased surface area between the anode and cathode. One particular characterization of the cell construction of the present invention comprises an electrochemical battery cell comprising a cell housing defining an interior space having an interior surface, a first terminal and a second terminal. The cell further comprises an inner electrode encapsulated by a separator and disposed within the interior space of the housing. The inner electrode has a thin cross section in a folded configuration and is formed such that an outer extent of the inner electrode is generally conforming to a contour defined by the interior surface of the cell housing. The inner electrode is in electrical communication with the second terminal of the housing. An outer electrode is disposed within the interior space of the housing such that it is in ionic communication with the inner electrode and in electrical communication with the first terminal of the cell housing.

A heavy metal-free rechargeable Zinc electrode for use in storage cells having alkaline electrolyte has been developed. The electrode includes a current collector and an active mass based on metallic zinc and zinc oxide powders, calcium hydroxide, indium hydroxide, indium sulfate, bismuth-oxide and a binder. The electrodes have been successfully used in Ni&#x2014;Zn and Ag&#x2014;Zn cells. The electrodes lead to environmentally benign alkaline cells. The electrodes have additional advantages over the prior art electrodes in terms of initial capacity and cyclability.

A rechargeable battery cell includes an anode with a major portion of active material, a cathode including MnO.sub.2 doped with bismuth, and a separator between the cathode and anode which substantially prevents bismuth from migrating from the cathode to the anode. The rechargeable battery cell has a high cycle life and does not contain toxic compounds found in conventional rechargeable batteries.

Rechargeable electrochemical cell with modified manganese oxide positive

A method of making a rechargeable battery electrode material containing manganese oxide is provided. The method includes preparing an aqueous solution of manganese nitrate and dissolving bismuth nitrate into the solution. The mixture is heated to evaporate the water contained in the mixture and is further heated to facilitate decomposition of the nitrates in the mixture to form a compound containing manganese oxide and bismuth oxide. The compound is maintained at a temperature of between about 200 to 300 degrees Celsius for an additional 12 hours. Thereafter, the compound is cooled and ground to a desired particle size for use as a rechargeable battery electrode material. The compound may alto be mixed with commercially prepared electrolytic or chemical manganese dioxide to obtain a highly rechargeable battery electrode material. A related battery cell is also disclosed.
