A lithium-ion battery or Li-ion battery is a type of that uses the reversible of Li ions into electronically solids to store energy. Compared to other types of rechargeable batteries, they generally have higher,, and and a longer and calendar life. In the three decades after Li-ion batteries were first sold in 1991, their volumetric energ.
