Batteries - Lithium
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 (comparable to a zinc–carbon or alkaline battery) to about 3.7 V.
By comparison, lithium-ion batteries are rechargeable batteries in which lithium ions move between the anode and the cathode, using an intercalated lithium compound as the electrode material instead of the metallic lithium used in lithium batteries.
Lithium batteries are widely used in products such as portable consumer electronic devices.
