ABSTRACT
Batteries are generally galvanic cells which convert chemical energy into electrical energy. As mobile sources of energy, we can no longer imagine life in the modern world without them. Every year in Germany, approximately 1 billion portable batteries are sold, an equivalent of around 30,000 tons (Table 19.1). We can state that 85% of the battery market comprises non-rechargeable primary batteries and 15% rechargeable secondary batteries.
