Contrary to the dominance of nickel-cadmium batteries in the many years, currently lithium-ion batteries are the most popular among portable devices. This can be attributed to the smaller weight of lithium as well as its electrochemical potential. The following are the benefits of using lithium-ion batteries.
The energy density of Li-on batteries is very high. During discharging, they experience the same characteristics as those of Ni-Cad batteries. Since the cells have a higher density, single cell designs can be made. Three Ni-Cad batteries have to be connected in series to march one Li-on battery. Hence most devices use only one battery cell instead of the many cells connected in series. Since there are new technological advancements such as electric vehicles, there is need for high density batteries to be used for them to function properly. Mobile devices also require Li-on batteries because the batteries can hold power for longer hence no need of regular recharges.
Maintaining these batteries is a lot easy and cheap. This is because, the batteries don’t require any cycling or memory to have the life of these batteries prolonged. Of all rechargeable batteries, Lithium-ion batteries have the lowest discharge rate hence able to store power for longer. This will means that you will be using the batteries for a long time because they will be holding power for a long time. Lithium-ion batteries are less harmful to the environment compared to nickel-cadmium batteries because of their chemical compositions. The Li-on batteries will not cause personal injuries to children or adults provided they are disposed of safely, and they don’t pollute the environment. The time between consecutive charges will be a lot higher because the batteries will lose very little power hence your device will utilize more of the power.
Finally, these batteries don’t need to be primed while discharging. Other batteries such as Ni-Cad require priming before their first charging. The Li-on batteries can just get charged for the first time without priming and they will still be ok. Lithium-ion batteries also come in several varieties, which is very important because they will have a wider range of applications. Because of this reason, any technology can be used for whichever application that it is required to. You will find some batteries which provide lesser power densities which are suitable for use in home electronics such as mobile devices. There are other batteries that provide much higher densities which makes them suitable for use in power tools and even electric vehicles. Either way, you need to get the right Li-on battery that will fit the purpose for which you want to use it for. This is the only way you can be sure that the battery you acquired will serve you well and for a long time.
