Lithium Primary Battery Chemistry

Depending on the design and chemical compounds used lithium cells can produce voltages from 1 5 v comparable to a zinc carbon or.

Lithium primary battery chemistry. Lithium batteries are primary batteries that have metallic lithium as an anode these types of batteries are also referred to as lithium metal batteries. They also weigh less than their nickel cadmium counterparts and hold their charge longer than other batteries in the case of these primary lithiums batteries that can be years. Cathode material is unique because the chemical reaction with lithium results in an open circuit voltage ocv of 1 8 volts. These are your standard aaa aa c d 9v and lantern batteries found in every grocery store.

The words are either written in full or shortened by their chemical symbols. Although the higher ocv of the lifes2 system is 1 8 volts the nominal or rated voltage. They stand apart from other batteries in their high charge density long life and high cost per unit. A series of letters and numbers strung together can be hard to remember and even harder to pronounce and battery chemistries are also identified in abbreviated letters.

Lithium is gaining a lot of popularity as an anode for a number of reasons. Many new battery sizes refer to both the batteries size and chemistry while older names do not. Non rechargeable lithium chemistry batteries which provide exceptionally high energy density produce about 1 5 v per cell and are thus similar to alkaline batteries. Other cathode materials combined with lithium will produce battery voltages above 2 0 volts.

However these current primary chemistries are exclusively based on inorganic materials with high cost low energy density or severe safety concerns. Best used to provide a very low to moderate amount of power for devices with occasional use a good primary cell non rechargeable battery offers lower cost longer shelf life and easier maintenance than rechargeable alternatives with similar capacity. Lithium ion is named for its active materials. Lithium batteries primary lithium batteries have a higher voltage than other batteries which means that it takes fewer to provide the same amount of power compared to other batteries.

Generally the negative electrode of a conventional lithium ion cell is made from carbon the positive electrode is typically a metal oxide the electrolyte is a lithium salt in an organic solvent. The three primary functional components of a lithium ion battery are the positive and negative electrodes and electrolyte. Here a novel lithium organic primary battery chemistry that operates through a synergetic reduction of 9 10 anthraquinone aq and fluoroethylene carbonate fec is reported. The electrochemical roles of the electrodes reverse between anode and cathode.

Lithium battery chemistry comprise a number of cell designs that use lithium as the anode. Battery types standard batteries primary cells. This summary is only for types relating to battery sizes. In this comparison of anode materials we can see some reasons why.
