Nickel cadmium battery D 4000mah 1.2v high temperature

Nickel cadmium battery D 4000mah 1.2v

The cadmium (Cd) in the negative electrode and the hydroxide ions (OH-) in the sodium hydroxide (NaOH) in the nickel-cadmium battery are chemically synthesized into cadmium hydroxide, which is attached to the anode and also emits electrons. The electrons travel along the wire to the cathode, and react with the nickel dioxide in the cathode and the water in the sodium hydroxide solution to form nickel hydroxide and hydroxide ions. The nickel hydroxide will adhere to the anode, and the hydroxide ions will return to hydrogen. In sodium oxide solution, the concentration of sodium hydroxide solution will not decrease with time.
