The storage of electrical energy is a significant
problem for the supply of energy, particularly as the
alternating current made available by power stations cannot be
directly stored.
Direct current, however, can be stored by converting the electrical
energy into chemical energy. The device which is suitable for this
is called an accumulator, or storage battery. In practice, several
accumulator cells are connected together in series to a
battery.
The students are familiar with such accumulators. This experiment
is intended to clearly explain the construction principle and the
mode of action of a lead accumulator.
Demonstrate how electrical energy can be stored chemically by
using, as example, a model of a lead accumulator.
