One of the notable features of lithium-ion batteries is the fact that they require minimal maintenance. There is no memory and the battery doesn't require periodic cycling to extend its lifespan. When compared to NiMH batteries or Ni-Cd batteries, you will notice that the discharge rate for Li-Ion batteries is less than 50%, which makes it perfect for use in fuel gauge applications.
The Li-Ion battery has high cell voltage and permits the production of metal polymer battery pack made up of one cell. This reduces to a significant degree the design of batteries. A lot of cell phones in the present use this type of design.
Nowadays electronic applications have lower supply voltages. This means that there are fewer cells in each pack of batteries. But, you might require greater current flow in order to achieve enough power for low voltages.
While it is safe for use, it is required to have an electrical protection system. However, this circuit can impede current flow and is an area in which experts have to study harder to find the solution. When they are not being used the Li-Ion batteries begin to get older.
The best solution is to keep them in a cool, dry location with a 40% charge level. The storage of batteries in such a manner reduces the time to aging.
It's true that the price of making lithium batteries is greater as compared to nickel-cadmium ones. Naturally, their cost of sale is higher as well, however, they are not prohibitive to purchase.
The users should not overlook the incredible power density of lithium-ion batteries that pave the way to bigger capacities and astonishingly low self-discharge capabilities.
