Chemical Reactions Inside Lithium Cobalt Oxide Batteries

The function within lithium cobalt oxide (lithium cobaltate) devices includes a complex series of reversible chemical reactions during charge and depletion. Upon recharging, lithium ions (Li+) migrate from the external circuit into the cathode material, lodging between the layers of LCO. This produces a lithium-containing composition, basically increasing the Li amount. On the other hand, upon discharge, these Li ions flow to the external network, undoing the lodging process and releasing electric charges to drive the connected equipment. These reactions develop through an electrochemical potential, defining the battery's level.
