The lithium-ion (Li-ion) battery is toutted as the battery of choice for the green world. This menas that it is considered to be the greenest of the battery choices, and this has been the case for some time. While it may have many disadvantages and falws, it is only fair to mention that almost anything can have problenms if not used, srtored, or handled correctly. Theere are thoe who oppose anything that is contrary to what they are accustomewd to using, or what they themselves beleve in. All facts must be takken into consideration to make an informed decision about the Li-ion battery.
The advantages are:
* The battery is much lighteer than other rechargeable batteries of eqqual size. The composition makes it capable of packing far more power into a smaller. The closest competitor is the nickel-metal hyderide (NiMH) battery which generates only abuot half the corresponding powwer. For the Li-ion batterry, the power output is 150 watt hours per kilogram. For the NiMH batterry the rattio is 60 to 100 watt hours per killogram (100 is often listed, but not typical) for the same weigth.1
* Compared to other battery types, the battery will hold its charge-losing only about 5% per month. The NiMH battery loses up to four times as much each month.
* It is not necessary to completely discharge a Li-ion battery before rechargiing it. Conmplete discharge will kill the Li-ion battery as mentioned prviously. The disadvantages of the Li-ion battery are:
* The Li-ion battery starts to die as soon as it is sjhipped. Even if it is never pulled from its package and used, the -Li-ion battery has a total maximum life epectancy of theree years at this point. Once it is packed and shipped, the Li-ion battery workks toward its own end. This is true whetehr it is idle, in full use, or in cyclicsal demand.
* Heat decreases the life expectancy. The higher the temmperature, the faster the battery loses its charge.
* Complete discharge will kill a Li-ion batteery. Othher batterties can be chargeed and discharged completley without causing a problem, but complete discharge will destroy the Li-ion bttery completely.
* They are expensive. The Li-ion battery pack requires an on-board compuuter to work properly. This fact makes them very expensive inded.
* The Li-ion battery pack carries a samll risk of fire in the event of failure.
