Battery Batch

Nickel-cadmium batteries are better known as NiCad or rechargeable batteries. They are made of two thin plates of nickel oxy-hydroxide and cadmium which are flattened together and rolled up into a cylinder shape. The nickel oxy-hydroxide acts as the anode, and the cadmium acts as the cathode. The catalyst is the electrolyte fluid which fills the battery, known as potassium hydroxide. This causes an electrical charge to build between the anode and the cathode.
