The simplest way to write the reaction for discharge in a lithium-ion battery is

(a) What are the oxidation numbers for cobalt in the two substances in the battery?
(b) In such a battery, what reaction occurs at the cathode? At the anode?
(c) An electrolyte is needed for ion conduction within the battery. From what you know about lithium chemistry, can the electrolyte in the battery be dissolved in water?
