Which statement concerning batteries and fuel cells is incorrect?
A fuel cell uses the reduction of atmospheric oxygen as the cathode.
A lithium ion battery is a secondary battery that use lithium in both the anode and the cathode.
An alkaline battery is a primary battery with a zinc anode, manganese cathode, and KOH as the electrolyte.
A lead-acid battery is a secondary battery that uses lead in both the anode and the cathode, and uses sulfuric acid as the electrolyte.
A Ni-Cad battery is a secondary battery with a nickel anode and cadmium cathode.
Option E is incorrect because in Ni-Cd battery is a secondary battery with a cadmium anode and nickel cathode.
Primary battery - the batteries cannot be used again. Only once it can be used. These batteries are not rechargeable.
Secondary battery - the batteries can be used again. These batteries are rechargeable.
A fuel cell uses the reduction of atmospheric oxygen as the cathode. - correct
A lithium ion battery is a secondary battery that use lithium in both the anode and the cathode. - correct
Lithium is used in anode as well as cathode for the discharge and recharge.
Alkaline battery - only once can be used, not rechargeable, primary battery. Anode = Zn, cathode = Mg, electrolyte = KOH
Lead acid battery -rechargeable, secondary battery. Anode = Pb, cathode = Pb, electrolyte = H2SO4
