Abstract: An electrode includes an electrode material, a polymer substrate, and a current collector. The electrode material comprises an electroactive material, and the electrode material forms an electrode material sheet. The electrode material sheet is disposed on the polymer substrate, and a current collector in electrical contact with the electrode material.

Abstract: In some embodiments, a battery comprises an anode, a cathode, a separator disposed between the anode and the cathode, and an electrolyte in fluid communication with the anode, the cathode, and the separator. The anode can be a porous metallic zinc anode. The porous metallic zinc anode comprises pure zinc electrode, a substrate coated with zinc, a zinc substrate with a coating layer, or combinations thereof.

Abstract: An alkaline battery comprises an anode, a cathode, a separator disposed between the anode and the cathode, a barrier layer disposed between the anode and the cathode, and an electrolyte in fluid communication with the anode, the cathode, and the separator. The barrier layer is at least one of: an organic polymer film or a porous inorganic layer or combinations thereof.

Abstract: Disclosed are systems and methods to generate backup and remote electrical power, including operating an internal combustion engine to rotate a standard electrical generator. This approach can be based on a variety of engine types such as but not limited to diesel, gasoline, turbine and many other engine types. Each of these technologies have respective efficiency curves based on engine speed, load and many other factors. Often the maximum efficiency point is not the current load demand of the generator system. The disclosed systems and methods are directed to enabling the various generator sets to operate at or near their peak efficiency while they are running, thereby improving the overall efficiency of the generator systems.
