Lithium- ion batteries are an assembly composed of many cells. Batteries that have lithium as their anode are called lithium batteries. Depending on the design and chemical compounds used, lithium cells can produce voltages from 1.5 V to about 3.8 V. Given its lightweight, high energy density and efficiency, lithium batteries are used in a wide range of portable consumer electronic devices, medical equipment, power backups, solar storage and in electric vehicles.
