High power battery

Silver—Iron Cells. The silver—iron battery system combines the advantages of the high rate capabiUty of the silver electrode and the cycling characteristics of the iron electrode. Commercial development has been undertaken (70) to solve problems associated with deep cycling of high power batteries for ocean systems operations. 

A second group of very high power batteries includes 12-V units with capacities between 5 and 85 Ah. These batteries have been optimized to a power density of 200 Wl at the 15-min diseharge rate. The typieal application is UPS. Due to the optimization towards extremely high power, however, the expected life is significantly shorter than for the 10-year battery. 

Sometimes other methods of classification are also used, for example, on the basis of the application (stationary or mobile batteries), shape (cylindrical, prismatic, disk-shape batteries), size (miniature, small-sized, m ium-sized, or large-sized batteries), electrolyte type (alkaline, acidic, or neutral electrolyte, with liquid or solid (solidified), or molten salt electrolyte), voltage (low voltage or high voltage batteries), electric power generation (low power or high power batteries), and so on.

A standard dry cell is made with a zinc anode (negative pole), in the form of a cylindrical pot, with a carbon cathode (positive pole) in the form of a central rod. The electrolyte is ammonium chloride in the form of a paste. Ammonium chloride and manganese dioxide are present in the remaining space between the electrolyte and carbon cathode. In some modem types of high-power batteries, the ammonium chloride has been replaced by zinc chloride. 

Providing electrical power at remote and inaccessible regions is not easy if commercial power lines are not in those locations. Currently, the power at these locations in most cases is provided by high-power batteries or conventional diesel generators. Both options have several fundamental problems, such as crude oil cost, greenhouse gas emissions, and continuous power capacity in the case of batteries. If a... 

Many combinations of electrode material and electrolyte can yield a cell. A few hundred possible cells are required to design a high-power battery. An Ni-Cd cell can be used in the design of a low-power rechargeable battery to power small electronic devices such as a minicomputer, musical recorders, and flash lamps for cameras. For a compact rechargeable battery, two components of the battery contribute to the mass and volume. First, the chemicals and materials used in the development of the battery strictly determine the physical parameters. Second, the mass and size of the packaging materials affect these parameters. 

Cost is a major factor for any battery pack used in an EV or HEV. A preliminary cost prediction study indicates that Li-ion batteries have a 50% higher cost over Ni-MH batteries, and a 40% higher cost over Ni-Cd batteries. Higher cost projections are valid only for the high-power batteries required to operate EVs or HEVs.
