Introduction

Many of the devices you use daily rely on rechargeable electric cells. In this module you have learned about the ability of electric cells to convert chemical energy into electrical energy. What changes occur when the cell from your MP3 player or digital camera is “recharged”?

 

In this lesson you will learn about rechargeable cells. You will learn how a recharging cell is an example of a different type of electrochemical cell, and you will learn why some cells can be recharged while others cannot be recharged.

 

Consider the following questions as you complete this lesson:
