5. Nickel-chromium battery works
The cadmium hydroxide (Cd) in the negative electrode and the hydroxide ion (OH-) in the sodium hydroxide (NaOH) form the cadmium hydroxide, and adheres to the anode while also emitting electrons. The electrons travel along the wire to the cathode, and the nickel dioxide at the cathode reacts with the water in the sodium hydroxide solution to form nickel hydroxide and hydroxide ions. Nickel hydroxide attaches to the anode and the hydroxide ions return to hydrogen. In sodium oxide solution, the concentration of sodium hydroxide solution does not decrease over time.
Discharge reaction type:
Negative Reaction: Cd +20H- -Cd(OH)2 +2e-
Positive Reaction: 2e-+NiO2+2H2O-Ni(OH)2+20H Total Reaction: Cd+NiO2+2H2O-Cd(OH)2+Ni(OH)2 Charge Reaction:
Positive Reaction: Ni(OH)2+2OH-->2e-+NiO2+2H2O Negative Reaction: Cd(OH)2+2e-- Cd+20H-
Total reaction: Cd(OH)2+Ni(OH)2->Cd+NiO2+2H20
