Lithium Cobalt Oxide Powder

Product Name: Lithium Cobalt Oxide Powder

Lithium Cobalt Oxide Description

The solid consists of layers of monovalent lithium cations that lie between extended anionic sheets of cobalt and oxygen atoms, arranged as edge-sharing octahedra, with two faces parallel to the sheet plane.

Lithium Cobalt Oxide is formally in the trivalent oxidation state. In each layer (cobalt, oxygen, or lithium), Lithium Cobalt Oxide Powder is arranged in a regular triangular lattice.

The lattices are offset so that the lithium atoms are farthest from the cobalt atoms, and the structure repeats in the direction perpendicular to the planes every three cobalt (or lithium) layers. signifying a unit cell with threefold improper rotational symmetry and a mirror plane.

The threefold rotational axis (which is normal to the layers) is termed improper because the triangles of oxygen (being on opposite sides of each octahedron) aligned. Batteries produced with Lithium Cobalt Oxide cathodes have very stable capacities but have lower capacities and power than those with cathodes based on nickel-cobalt-aluminum (NCA) oxides. Issues with thermal stability are better for Lithium Cobalt Oxide cathodes than other nickel-rich chemistries although not significantly.

This makes Lithium Cobalt Oxide batteries susceptible. Lithium Cobalt Oxide decomposition generates oxygen, which then reacts with the organic electrolyte of the cell. This is a safety concern due to the magnitude of this highly exothermic reaction, which can spread to adjacent cells or ignite nearby combustible material. In general, this is seen for many lithium-ion battery cathodes.
