The document discusses different types of batteries used in consumer electronics. It begins by noting the rising demand for battery materials. It then provides an overview of primary and secondary batteries, their basic components and chemical reactions, as well as common chemistries like carbon-zinc, alkaline, nickel-cadmium, nickel-metal hydride, and lithium-ion. The document concludes by discussing future battery research areas like nanotechnology and possibilities like micro batteries and paper batteries.

2. Batteries are a Large CommodityThe demand for materials used in the production of batteries and fuel cells has been on a steady rise. According to a study done by the Freedonia Group, world demand for materials used in the manufacture of batteries will rise 3.9 percent per year to $22.8 billion in 2012.

3. So…What are Batteries?Batteries are devices that convert chemical energy into electrical energy, consisting of a group of electric cells that are connected to act as a source of direct current.

4. Batteries are used in portable electronic applications such as garage door openers and electric lawn mowers

5. Battery ClassificationsBatteries are divided into two categories:PrimarySecondary

6. Primary Batteries Advantages

7. Convenience

8. lower initial cost

9. higher capacity

10. Disadvantages

11. Continuous replacement

12. Greater long term expense

13. WastePrimary cell batteries are designed to be used once and then discarded as their electrochemical reactions are not reversible.

14. Secondary Batteries Advantages

15. Can replace primary batteries in some devices
