Lithium Cobalt Oxide Battery Chemical Reaction

A prototype li ion battery was developed by akira yoshino in 1985 based on earlier research by john goodenough m.

Lithium cobalt oxide battery chemical reaction. By breaking through the energy density limits step by step the use of lithium cobalt oxide based li ion batteries lco based libs has led to the unprecedented success of consumer electronics over the past 27 years. 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. 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. Stanley whittingham rachid.

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 temperature of the cell rises due to the chemical reactions between the organic solvent and electrode materials leading to cell failure explosion. The cobalt and oxygen bond together to form layers of. The chemical reaction is prompted because of the.

Lithium cobalt oxide is a dark blue or bluish gray crystalline solid and is commonly used in the positive electrodes of lithium ion batteries. The most common lithium ion cells have an anode of carbon c and a cathode of lithium cobalt oxide licoo 2. Less flattering are safety and cost. 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.

It shares similarities with nmc by offering high specific energy reasonably good specific power and a long life span. Lithium nickel cobalt aluminum oxide battery or nca has been around since 1999 for special applications. Lithium nickel cobalt aluminum oxide linicoalo 2 nca. While the exact material ratios vary by manufacturer the common combinations are usually 60 nickel 20 manganese and 20 cobalt.

Recently strong demands for the quick renewal of the properties of electronic products ever. 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. 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.
