They charge under a constant current and switch to a continuous voltage later in the charging cycle. The charging process reduces the current as the battery reaches its full capacity to prevent overcharging. For instance, a lithium-ion battery may charge at a constant current of 1C until it comes to around 70% capacity, after which the charger switches to a regular voltage mode,
These lithium-ion batteries have become crucial technologies for energy storage, serving as a power source for portable electronics (mobile phones, laptops, tablets, and cameras) and vehicles running on electricity because of their enhanced power and density of energy, sustained lifespan, and low maintenance [68,69,70,71,72,73].

The Li-ion Power Cell permits a continuous discharge of 10C. This means that an 18650 cell rated at 2,000mAh can provide a continuous load of 20A (30A with Li-phosphate). The superior performance is achieved in part by lowering the internal resistance and by optimizing the surface area of active cell materials. Low resistance enables high
CP offers potential for high rate charging with sustained lower impedance during the battery lifespan. Moreover, the use of a constant power charging protocol might help to mitigate some of the challenges associated with charging Li-S batteries, such as the formation of lithium dendrites and the loss of active sulfur material [21, 22].
One of the unique qualities of nickel- and lithium-based batteries is the ability to deliver continuous high power until the battery is exhausted; a fast electrochemical recovery makes it possible. Lead acid is slower and this can be compared to a drying felt pen that works for short markings on paper and then needs rest to replenish the ink.
The maximum continuous discharge current is the highest amperage your lithium battery should be operated at perpetually. This may be a new term that’s not part of your battery vocabulary because it is rarely if ever, mentioned with lead-acid batteries.
Moreover, the use of a constant power charging protocol might help to mitigate some of the challenges associated with charging Li-S batteries, such as the formation of lithium dendrites and the loss of active sulfur material [21, 22]. As is deeply known, when a Li-S battery is charged, lithium ions are deposited on the surface of the lithium anode.
Conclusive summary and perspective Lithium-ion batteries are considered to remain the battery technology of choice for the near-to mid-term future and it is anticipated that significant to substantial further improvement is possible.
Lithium batteries are also sensitive to the number of charging and discharging cycles; the greater the number of cycles the less the capacity due to a loss of active material within the cell and primarily loss of lithium inventory [ 15 ].
