Li-ion batteries can be used multiple times due to their wide applicability. Tey have high energy density and a long cycle life since Li ions shift from one side of the batter to another during charging and discharging. Recharging these batteries can be done endlessly, which lowers the replacement need. A wide range of appliances such as laptops, smartphones, and vehicles use these batteries as a reliable power source. These batteries are lightweight too, which increases their portability
