"When the lithium-ion is taken out of the oxide (in the cathode), the lithium-ion has a positive charge, so the cobalt changes its oxidation state so that the oxide stays electrically neutral. A small amount of the cobalt changes its electronic character from oxidation state +3 to +4 to account for the removal of the lithium-ion," said Abraham.
