Why are Lithium-Ion battery packs popular? Of all the metals, lithium is the lightest. It has the highest electrochemical potential and provides the highest energy density per weight.
Qualities of Lithium-Ion Batteries
Due to the fact that it has the highest energy density, the Li-Ion battery has an edge over the normal nickel-cadmium battery. Due to improvements incorporated in the active compounds of the electrode, the Li-Ion battery has an electric power density which is almost three times more than that of the nickel-cadmium battery. You can also buy customized battery packs of lithium batteries from online sources.
Besides this, the load capacity of a lithium battery is also appreciable. It has a flat discharge curve which gives you the chance to use the saved power in a voltage range of your choice.
One of the noteworthy qualities of lithium-ion battery packs is that they require low maintenance. Memory is absent and the battery requires no scheduled cycling to extend its life. When you compare them with NiMH batteries and Ni-Cd batteries, the self-discharge of Li-Ion battery is less than fifty percent, making it ideal for fuel gauge applications.
The Li-Ion battery features high cell voltage and allows the manufacturing of battery packs that consist of a single cell only. This simplifies to a great extent the battery design. Several cell phones of today run on such design.
In modern times, electronic applications feature low supply voltages. This demands fewer cells for every pack of batteries. However, you may need a higher current flow to get sufficient electrical power at low voltages.
