Lithium-Ion Battery A lithium-ion (Li-ion) battery is a rechargeable battery that stores energy by allowing lithium ions (Li+) to move in and out of an electrically conductive material. This type of battery is commonly used in portable electronics and electric vehicles. For a long time, nickel-cadmium batteries were the only option for portable devices like […]
