Batteries Andrew G., Santino M., Sam H., Cameron P. Mr. Winterhalter Period: 2 • • • • Batteries act like mini, portable generators Batteries start with chemical energy The chemical energy is stored in chemical compounds Electric chemical cells convert chemical energy into electrical energy Batteries • Luigi Galvani created he first batteries on accident when he was studying the anatomy of a frog. He used a brass hook to hold the leg and touched it to a iron railing and noticed the leg muscle twitched. • The first modern batteries were layers of iron, zinc, and paper soaked in salt water. The First Battery • Several cells are stacked together make a batteries • Modern batteries are single Electrochemical cells Electrochemical Cells • An electrochemical cell in which the electrolyte is a liquid is a wet cell. • A dry cell is a electrochemical cell in which the electrolyte has the consistent of a paste. Wet and Dry Cells • You can recharge the cells by into valuable reactants. • The reactants in a rechargeable battery are made from nickel and cadmium.
