High Quality Content by WIKIPEDIA articles! Lithium batteries are disposable (primary) batteries that have lithium metal or lithium compounds as an anode. They stand apart from other batteries in their high charge density (long life) and high cost per unit. Depending on the design and chemical compounds used, lithium cells can produce voltages from 1.5 V (same as zinc–carbon battery or alkaline battery) to about 3.7 V. Lithium batteries are widely used in products such as portable consumer electronic devices.
