Lithium batteries are primary batteries that have metalliclithium as an anode. These
types of batteries are also referred to as lithium-metal batteries. They stand apart
from other batteries in their high charge density (long life) and high cost per unit.
The practical difference between Lithium batteries and Lithium-ion (Li-ion)batteries
is that most Lithium batteries are not rechargeable but Li-ion batteriesare rechargeable.
A lithium battery should never be recharged while lithium-ion batteries are designed to
be recharged hundreds of times.
Lithium ion batteries have high energy density and cost less than lithium polymer.Lithium
polymer batteries are light weight and have improved safety . However their cost is high
(30% average) as compared to lithium ion. Also the the energy density of Li-Polymer
battery compared to Li-Ion Batteries is quite less.
The electrodes of a lithium-ion battery are made of lightweight lithium and carbon.Lithium
is also a highly reactive
element, meaning that a lot of energy can be stored in its atomic bonds. This translates
into a very high energy density for lithium-ion batteries.
The typical estimated life of a Lithium-Ion battery is about two to three years or 300 to
500 charge cycles, whichever occurs
first. One charge cycle is a period of use from fully charged, to fully discharged, and fully
Storing large amounts of energy, whether it's in larger rechargeable batteries, or smaller
disposable batteries, can be inherently dangerous. The causes of lithium battery failure
can include puncture, overcharge, overheating, short circuit, internal cell failure and
Lithium batteries with more than 100 watt hours may be allowed in carry-on bags with
airline approval, but are limited to two spare batteries per passenger. Looselithium
batteries are prohibited in checked bags.
