ABSTRACT
The electric battery is an important ingredient in future scenario of a solar-hydrogen-based society. Many test to bring the electromobile into being and the limitations which became apparent on account of the shortcomings of batteries. Small and light cars with an action radius of some 50 mi can be operated with lead-acid batteries. The development of these batteries has met with some difficulties; there is hardly any gain in weight feasible. There is a wide margin to cover, to make batteries and electromotors compete with gasoline-driven motors. In this respect, hydrogen-fuel cells would be the better approach. However, batteries are needed in many cases where storage of electricity at remote locations is a necessity. Especially in connection with solar systems, batteries are a natural storage medium. Also, in a number of applications where an energy reserve for short-haul transport is desired, the battery is a necessity.
