Lithium Ion Battery : Working, Applications, Future Use Part-2

Lithium-ion batteries power the lives of millions of people each day

Advantages of Li-ion Batteries

• High energy density - potential for yet higher capacities. 
• Does not need prolonged priming when new. One regular charge is all that's needed. 
• Relatively low self-discharge - self-discharge is less than half that of nickel-based batteries. 
• Low Maintenance - no periodic discharge is needed; there is no memory. 
• Specialty cells can provide very high current to applications such as power tools.

Disadvantages of Li-ion Batteries

• Requires protection circuit to maintain voltage and current within safe limits. 
• Subject to aging, even if not in use - storage in a cool place at 40% charge reduces the aging effect. 
• Transportation restrictions - shipment of larger quantities may be subject to regulatory control. This restriction does not apply to personal carry-on batteries. 
• Expensive to manufacture - about 40 percent higher in cost than nickel-cadmium. 
• Not fully mature - metals and chemicals are changing on a continuing basis.

Future of Lithium-Ion batteries

• When Tesla launched their Model , it was then that Lithium-ion batteries became a household name.
• It was then that the world stopped and took notice of a battery could virtually power a car for more than 300 miles.
• As the market for electric automotive increases and as they become more and more accessible to the common man, the costs surrounding the lithium ion battery technology will also come down.
• Apart from that, with the world pushing for maximum portability of most gadgets, there is a huge market for the lithium-ion technology.
• Today, lithium-ion is the fastest growing and most promising battery chemistry.

Facts: 

• A typical lithium-ion battery can store around 150 watt-hours of electricity in a 1 battery of 1 kilo whereas A lead-acid battery can store only 25 watt-hours per kilo.
• Using lead-acid technology, it takes 6 kilograms to store the same amount of energy that a 1 kilogram lithium-ion battery can handle
