Nickel-Zinc Storage Batteries as Energy Sources for Electric Vehicles

The first part of this paper describes factors influencing the transport output of battery driven delivery vans of the 2, 7t class. Taking into account the energy densities of batteries, the probability of their practical realization, their development costs and thermal problems as well as the payload and the necessary range of delivery vans in urban applications, a battery with an energy density of 40-60 Wh/kg can serve as energy source for a practical electric vehicle.

The second part gives details of a new developed Ni/Zn-battery which has an energy density of 45 Wh/kg and therefore corresponds to the mentioned demand.
