Li-ion
battery packs are very popular these days.
There are so many reasons why these are widely preferred by the people today.
Lithium-Ion provides the highest energy density per weight and it has the
highest electrochemical potential. Lithium is the lightest among all the
metals.
People
prefer Li-on battery to normal nickel cadmium battery because it has the
highest energy density.
The electric power density of the Li-on battery is almost three times greater
than that of the nickel cadmium battery. Apart from this it has a considerable
load capacity. Its flat discharge curves give you the chance to use the saved
power in a voltage range of your choice.
The
most important quality of these battery packs is they need low maintenance.
Moreover the battery does not require scheduled cycling to extend its life. These batteries feature high cell voltage. The Li-Ion battery technology is
one of the fastest growing trends due to some good reasons. These kinds of
batteries have the best energy to weight ratio. They have absolutely no memory
and can continuously accept the maximum charge. In addition, they have very
slow rate of charge loss when the battery is disengaged.
There is a difference between
Lithium and Lithium Ion batteries. A lithium battery is a disposable power
source composed of lithium metal. These kinds of batteries cannot be recharged.
However, Lithium Ion batteries are rechargeable.
The advantages of Lithium Ion
technology-
(i) These kinds of batteries are
light in weight and hold a lot of power in comparison to other rechargeable
batteries.
(ii) These batteries hold their
charge for a longer time and provide a steady power. While other batteries
consistently loose power with the time these Li-on batteries remain strong till
the end.
(iii)They store more power than
nickel Cadmium batteries.
With
all the advantages given above, price may be an issue as it is more expensive
than the usual batteries. The chargers and the batteries are highly expensive
because the manufacturing process that both undergoes, is highly complex. Moreover, these are not usually
manufactured in bulks as compared nickel cadmium batteries.
