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.
