Heart pacemakers are often powered by lithium-silver chromate “button” batteries. The overall cell reaction is:
2Li(s) + Ag2CrO4(s) --------> Li2CrO4(s) + 2Ag(s)
Lithium metal is the reactant at one of the electrodes of the battery. Is it the anode or the cathode?
1 answer
The Li==> Li^+ + e is the anode. That is the one losing electrons.
