What advantages can lithium-ion batteries offer?
When it comes to usefulness and safety, lithium-ion batteries outperform other types of batteries like lead-acid batteries.
Compared to conventional batteries, lithium-ion batteries are more powerful and compact.

Lead-acid batteries are not the only secondary batteries that can be recharged and used again, like lithium-ion batteries. Lead-acid batteries may also be replaced by nickel-metal hydride and nickel-cadmium batteries. When compared to these batteries, lithium-ion batteries have the clear benefit of being lightweight, compact, and powerful.
The greatest voltages that these batteries can generate at the same size are 2.1V for lead-acid batteries, 1.2V for nickel-metal hydride batteries, and 1.25V for nickel-cadmium batteries, when comparing their features. In contrast, lithium-ion batteries have the capacity to generate voltages of up to 3.2 to 3.7V.
Lithium-ion batteries withstand repeated charging and draining with good resilience.
Unlike other secondary batteries, lithium-ion batteries do not produce energy through chemical processes. Because of this, their electrodes degenerate less than those of other secondary batteries, enabling them to withstand repeated charging and discharging with great resilience.
Fast charging of lithium-ion batteries is possible.
The rapid charging time of lithium-ion batteries is one of its main advantages. It is worth noting, however, that secondary batteries other than lithium-ion batteries are also capable of rapid charging. However, fast charging was not used in practice since it was impossible to tell when the charging of nickel-metal hydride and nickel-cadmium batteries was complete. Lithium-ion battery fast charging has been used since the charger can sense when the charging process is complete.
Wireless charging is supported by lithium-ion batteries.
Similar to rapid charging, secondary batteries other than lithium-ion batteries can also be charged wirelessly, or without a charging cord. Wireless charging was used for lithium-ion batteries, which were already anticipated to become widely used, despite the fact that the technology was just invented in 2007. A technology that will one day allow electric cars to be charged just by parking them in a parking lot is the subject of research.
Lithium-ion batteries can withstand self-discharge, or natural discharge.
Batteries exhibit a natural discharge process even when they are not being used, a phenomenon known as “self-discharge.” For instance, low voltage may prevent you from turning over the starter while attempting to start the engine of a car that hasn’t been driven in more than a month. The phenomenon commonly referred to as “dead battery” arises from self-discharge.
Self-discharge happens when a battery undergoes gradual chemical reaction, even if it is only placed in inactive storage. Because of this, lithium-ion batteries almost never self-discharge because they employ a battery reaction that is somewhat different from the battery reaction seen in other secondary batteries.
It should be noted that even in cases where cellphones and PCs with lithium-ion batteries are not in use, the battery may drain. In this instance, it is because, in order for the gadget to switch on right away, it has not been fully shut off and is still drawing a tiny quantity of energy even with the screen off.
