LOW-COST, HIGH-ENERGY CATHODES FOR MAGNESIUM PERCHLORATE BATTERIES.
Abstract
Mercuric oxide cathodes on expanded silver grids have proven their effectiveness in magnesium/magnesium perchlorate reserve type batteries. However, high cost and the critical category of both mercury and silver compounds led to investigations on establishing a low-cost, high-energy depolarizer on an inexpensive grid to replace the mercuric oxide on silver cathode. The report presents findings and preliminary room temperature discharge data at a medium (two-hour) rate primarily for three materials: manganese dioxide, cupric oxide and meta-dinitrobenzene. Data is also presented on various halide depolarizers which did not prove to be nearly as promising. It appears that especially m-dinitrobenzene and manganese dioxide can be developed to the point where they will surpass the performance of mercuric oxide in paractical cells. This, coupled with their low cost, would make possible the development of a much needed, inexpensive, highly efficient expendable battery for operation from -40F to +125F for modern communication applications.
