Benefits, advantages, limitations Lithium-Ion Batteries

Benefits: The Li-Ion battery receives good qualifications as far as performance and trustworthiness and have found a strong niche of market with portable devices demanding a reduced form factor.
The most popular uses are the wireless telephones and notebooks.
A field in which Li-Ion has been little favorable is in applications that require occasional use of the battery.
In one laptop that is fed mainly by AC, for example, the Li-Ion battery ages with time and the complete benefits of the battery cannot be perceived.
For these applications, other chemicals of battery can be more appropriate. High levels of temperature within some laptops also cause that Li-Ion fails prematurely. Anyway, tests of field is developing, that Li-Ion supports better the heat than Neither
The polymeric lithium systems that are in an early stage of their production, are fighting to reach and to exceed the performance of the Li-Ion batteries.
The high initial cost and the limited supply are the main disadvantages. Once produced in massive form, one hopes that the lithium-polymer batteries are cheaper than those of Li-Ion because they are possible simpler methods of packing.
Like advantages, the lithium-polymer provides densidades of energy slightly more discharges and reduced weight.
Standard norms have not settled down of form for lithium-polímetro batteries then this battery can virtually be molded to any form and size.

Warnings: The Li-Ion batteries have VHD of energy.
It must have precaution when manipulating and try.
They are not due to cortarcircuitar, to overload, to break, to mutilate, to apply invested polarity, to expose to high temperature or to disarm.

Advantages of the Li-Ion Batteries
- HD of potential energy for capacities still majors.
- Relatively low Self-discharge - the self-discharge is smaller in the middle of the one than they undergo Nicd and NiMH
- Little Maintenance. periodic unloadings without effect are not required memory.

Limitation of the Li-Ion Batteries
It requires protective circuit - the circuit of protection limits the voltage and the current. The battery is safe if it is not forced.
It holds to the deterioration of the passage of time, even though one is not in use - storing the battery in fresh place and to the 40 percent of the load state the aging is reduced
Subject to transfer regulations - the transfer of important amounts of batteries of Li-Ion can be susceptible of regulatory controls. This restriction is not applied to personal movements.
Face to make - near a forty percent more expensive than Nicd. Better manufacturing techniques and the rare metal replacement with lower alternative costs probably will reduce the price
Not totally mature - changes in metal and the chemical combinations affect the test resultses of the battery
