Three important developments regarding lithium batteries occurred in the 1980s. Three volt lithium primary cells such as the CR123A type and three volt button cells are still widely used, especially in cameras and very small devices. Lewis, but commercial lithium batteries did not come to market until the 1970s in the form of the lithium-ion battery. Experimentation with lithium batteries began in 1912 under American physical chemist Gilbert N. The low atomic weight and small size of its ions also speeds its diffusion, suggesting that it would make an ideal material for batteries. Lithium is the metal with lowest density and with the greatest electrochemical potential and energy-to-weight ratio. Lithium-ion battery Curve of price and capacity of lithium-ion batteries over time the price of these batteries declined by 97% in three decades. The most common type of lithium cell used in consumer applications uses metallic lithium as the anode and manganese dioxide as the cathode, with a salt of lithium dissolved in an organic solvent as the electrolyte. As designed these primary systems use a charged cathode, that being an electro-active material with crystallographic vacancies that are filled gradually during discharge.ĭiagram of lithium button cell battery with MnO 2 (manganese dioxide) at cathode. The battery requires from 0.15 to 0.3 kg of lithium per kWh. The term "lithium battery" refers to a family of different lithium-metal chemistries, comprising many types of cathodes and electrolytes but all with metallic lithium as the anode.

Lithium batteries are widely used in portable consumer electronic devices. Pure lithium will instantly react with water, or even moisture in the air the lithium in lithium-ion batteries is a less reactive compound. Lithium is especially useful, because its ions can be arranged to move between the anode and the cathode, using an intercalated lithium compound as the cathode material but without using lithium metal as the anode material. 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.ĭisposable primary lithium batteries must be distinguished from secondary lithium-ion or a lithium-polymer, which are rechargeable batteries and contain no metallic lithium. They stand apart from other batteries in their high charge density and high cost per unit. Since 2007, Dangerous Goods Regulations differentiate between lithium metal batteries (UN 3090) and lithium-ion batteries (UN 3480). However, rechargeable lithium metal batteries are also under development.
Most lithium metal batteries are non-rechargeable. These types of batteries are also referred to as lithium-metal batteries after lithium-ion batteries had been invented. Lithium metal batteries are primary batteries that have metallic lithium as an anode. The top object is a battery of three lithium-manganese dioxide cells, the bottom two are lithium-iron disulfide cells and are compatible with 1.5-volt alkaline cells. For the common rechargeable batteries, see Lithium-ion battery. This article is about disposable lithium batteries.
