Different Types Of Batteries And Their Verified Function

Primary lithium battery is disposable (primary) batteries that have lithium metal or lithium compounds as an anode. Depending on the design and chemical compounds used, lithium cells can produce voltages from 1.5 V to about 3.7 V, over twice the voltage of an ordinary zinc鈥揷arbon battery or alkaline battery. Lithium batteries are widely used in products such as portable consumer electronic devices.Lithium primary batteries account for 28% of all primary battery sales in Japan but only 1% of all battery sales in Switzerland. In the UK and EU only 0.5% of all battery sales including secondary types are lithium primaries.


The term "power battery"refers to a family of different chemistries, comprising many types of cathodes and electrolytes.The most common type of lithium cell used in consumer applications uses metallic lithium as anode and manganese dioxide as cathode, with a salt of lithium dissolved in an organic solvent.Disassembled CR2032 battery From left-negative cup from inner side with layer of lithium (oxidized in air), separator(porous material), cathode (manganese dioxide), metal grid-current collector, metal casing (+)(damaged during opening the cell), on the bottom is plastic sealing ring.

Another type of lithium cell having a large energy density is the lithium-thionyl chloride cell. Lithium-thionyl chloride batteries or li-ion battery are generally not sold to the consumer market, and find more use in commercial/industrial applications, or are installed into devices where no consumer replacement is performed. In this cell, a liquid mixture ofthionyl chloride(SOCl2) and lithiumtetrachloroaluminate(LiAlCl4) acts as the electrolyte and respectively. A porous carbon material serves as a cathode current collector which receives electrons from the external circuit. Lithium-thionyl chloride batteries are well suited to extremely low-current applications where long life is necessary, such as wireless alarm systems.
