Nickel Cadmium Cell

Nickel-cadmium cell was developed by Waldemar hunger in 1889.

The positive plate is built up from a number of steel tubes made of perforated steel. The negative plate is of cadmium. The use of cadmium reduces the internal resistance of the cell. When the Nike cadmium cell is in charge condition, the active material of the +ve plate (Anode) is Ni(OH)4 and the negative plate is cadmium. The electrolytes are a solution of potassium hydroxide with a small addition of lithium hydrate. The specific gravity of the electrolyte is 1.2. When the cell really charges the chemical process is reversed I. e. Positive plate is converted into Ni(OH)4and negative plate to a CD. DISCHARGING: When the cell discharging the potassium hydroxide is dissociative into k+ At anode Ni(OH)4 +2k------ 2kOH + Ni(OH)2 .thos anode is converted from ni(oh)4 to no oh 2 and cathode is converted from cadmium anode whereas the K+ ion move towards the cathode. A nickel-cadmium cell can be charged in a very short time I. e. Say 1 hour. A nickel-cadmium cell can be used up to 20 years of service. Main properties of alkaline cell nickel and Cadmium cell. The main properties are. It's ace. E. M. F. Per cell is 1.2V. It's weightless. Its average life is 10 years. Efficiency is about 80 percent Do. I am not sure if I can do it again and again and again and again and again and again and again and again and again and again and again and again and again the UK. Did. She's. Diana. Sksks. Slams.
