Chemical Reactions Inside Lithium Cobalt Oxide Batteries

The operation within lithium cobalt oxide (lithium cobaltate) cells consists of a complex sequence of cyclic chemical reactions during energizing and depletion. Upon energization, lithium ions (Li+) migrate from the external network into the positive electrode material, inserting between the layers of lithium cobaltate. This creates a lithium-containing compound, effectively increasing the lithium amount. Conversely, throughout discharge, these Li ions go back to the external circuit, undoing the intercalation process and releasing electric charges to energize the joined equipment. These responses develop across an electronic potential, determining the cell's voltage.
