Period 5

The first battery was invented by Alessandro Volta. He created it by sticking together layers of zinc, silver, and wet paper. Volta placed copper wire at each end and allowed a current to flow.

The first battery was an electrochemical cell.

Chemical reactions occur between electrolytes and electrodes in an electrochemical cell.

In an electrochemical cell, zinc and aluminum release more electrons.

Chemical energy is stored in chemical compounds.

Batteries are made by combining two or more electrochemical cells.

A wet cell battery is surrounded by a liquid and they tend to be bigger.

A dry cell battery is surrounded by paste and are more commonly used.

Some kinds of batteries can be recharged by reversing the flow of electrons.
