Nickel Cadmium Battery

The battery has a nickel-hydroxide cathode, a cadmium anode, and aqueous potassium hydroxide electrolyte.

The overall reaction is:

2NiOOH + 2H2O + Cd <=> 2Ni(OH)2 + Cd(OH)2



Memory Effect

If these batteries are discharged only partially before recharging, the cells have a tendency to act as if they have a lower storage capacity than they actually designed for; this is the memory effect.

They can often be restored to full capacity with a few cycles of discharge and recharge.
