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

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.

Electrochemical Cells

• Several cells are stacked together make a batteries

• Modern batteries are single Electrochemical cells

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.

Dead & Rechargeable Batteries

• You can recharge the cells by into valuable reactants.

• The reactants in a rechargeable battery are made from nickel and cadmium.
