LITHIUM ION BATTERIES

ADVANTAGES

• High energy density: The much greater energy density
• Their rate of self-discharge is much lower than that of other rechargeable cells

HOW LONG DO THEY LAST?

• Batteries that are properly cared for (charged and used often, stored in a cool, dry place, and not dropped) will last for 500 – 1000 charges or approximately two to three years.

USES

• Digital Cameras: many digital cameras are able to use lithium batteries, dramatically increasing the number of photographs that can be taken between battery changes.
• Pacemakers; and other implantable medical devices use specially designed lithium-iodide batteries that can last 15 years or longer before replacement.

• Lithium batteries are commonly used as power sources for portable electronics and implanted medical devices. Though more expensive than ordinary alkaline batteries, lithium batteries have a significantly longer lifespan.
• Miscellaneous Devices: Lithium batteries are used to power an increasing number of devices, such as thermometers, remote car locks, laser pointers, MP3 players, hearing aids, calculators and battery backup systems in computers. Remote control toys also use lithium batteries, with the batteries frequently outliving the toys themselves.
