.
Lithium is a lightweight metal that an electric current can easily pass through. Lithium ions make a battery rechargeable because their chemical reactions are reversible, allowing them to absorb power and discharge. .
Lithium-ion batteries have higher voltage than other types of batteries, meaning they can store more energy and discharge more power for high-energy uses like driving a car at high speeds or providing emergency. .
Batteries store energy by shuffling ions, or charged particles, backward and forward between two plates of a conducting solid called electrodes. The exact chemical composition of these electrode materials determines. .
In part because of lithium’s small atomic weight and radius (third only to hydrogen and helium), Li-ion batteries are capable of having a very high voltage and charge storage per unit mass and unit volume. [pdf]
