Abstract :
The capability of lead-acid batteries for supplying very high power for a short time is discussed. An example is given of a 400-metric-ton hypersonic passenger-carrying airplane that could be accelerated to Mach 2.3 on a launch ramp. During the last second of a 3-g acceleration, the plane´s kinetic energy increases by a 2.6 MWh increment. The 9300 MW of power required during this last second is not a desirable load for an electric utility, but it could be supplied with lead-acid batteries. Various lead-acid batteries are evaluated for applications with these kinds of requirements. Alternatives to batteries are briefly discussed
