1. Batteries Andrew G., Santino M., Sam H., Cameron P. Mr. Winterhalter Period: 2

2. Batteries 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

3. The First Battery 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.

4. Electrochemical Cells Several cells are stacked together make a batteries Modern batteries are single Electrochemical cells

5. Wet and Dry 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.

6. Dead & Rechargeable Batteries You can recharge the cells by into valuable reactants. The reactants in a rechargeable battery are made from nickel and cadmium.
