Lithium Cobalt Oxide Battery Chemical Reaction

A lithium ion battery or li ion battery abbreviated as lib is a type of rechargeable battery lithium ion batteries are commonly used for portable electronics and electric vehicles and are growing in popularity for military and aerospace applications.

Lithium cobalt oxide battery chemical reaction. The negative electrode is generally made from carbon graphite and the electrolyte varies from one type of battery to another but isn t too important in understanding the. The positive electrode is typically made from a chemical compound called lithium cobalt oxide licoo 2 or in newer batteries from lithium iron phosphate lifepo 4. Stanley whittingham rachid. Currently the most popular lithium ion technology is the lithium cobalt oxide lco battery which has a cathode composed of licoo 2 the main feature of the lco battery is the high energy density translating into a long run time for portable devices such as cell phones tablets laptops and cameras.

Lithium cobalt oxide is a dark blue or bluish gray crystalline solid and is commonly used in the positive electrodes of lithium ion batteries. Lithium nickel cobalt aluminum oxide linicoalo 2 nca. The chemical reaction is prompted because of the. A prototype li ion battery was developed by akira yoshino in 1985 based on earlier research by john goodenough m.

So for lithium cobalt oxide batteries with liquid electrolyte i was able to find a good source describing the problem of thermal runaway. Recently strong demands for the quick renewal of the properties of electronic products ever. When charging the battery the breakdown of lithium cobalt oxide occurs li ions travel through electrolyte solution and bond to negatively charged anode this is because when charging electrons are sent to graphite causing a negative charge and attraction to li ions. Lithium nickel cobalt aluminum oxide battery or nca has been around since 1999 for special applications.

The most common lithium ion cells have an anode of carbon c and a cathode of lithium cobalt oxide licoo 2. Lithium cobalt oxide sometimes called lithium cobaltate or lithium cobaltite is a chemical compound with formula licoo 2 the cobalt atoms are formally in the 3 oxidation state hence the iupac name lithium cobalt iii oxide. In fact the lithium cobalt oxide battery was the first lithium ion battery to be developed from the pioneering work of r yazami and j goodenough and sold by sony in 1991. It shares similarities with nmc by offering high specific energy reasonably good specific power and a long life span.

Lithium nickel manganese cobalt oxide linimncoo 2 batteries are made using several different elements commonly found in other li ion batteries and use a combination of nickel manganese and cobalt for the cathode. Less flattering are safety and cost. The temperature of the cell rises due to the chemical reactions between the organic solvent and electrode materials leading to cell failure explosion.
