The nickel-hydrogen secondary battery system, developed in the early 1970s, has become the system of choice for geostationary earth orbit (GEO) application. However, for low earth orbit (LEO) satellites with long expected lifetimes the nickel positive limits performance. This requires derating of the cell to achieve very long cycle life. A new system, rechargeable MnO2-hydrogen, which does not require derating, is described. For LEO applications, it promises to have longer cycle life, higher rate capability, a higher effective energy density, and much lower self-discharge behavior than those of the nickel-hydrogen system
