How does An Alkaline Battery Work?

An alkaline battery works when a stream of electrons is applied to the anode and cathode, or positive and negative, ends of the battery, which are connected with an electrolyte. In an alkaline battery, the anode is zinc, the cathode is manganese dioxide, and the electrolyte is potassium hydroxide. The electrons react with these chemicals and generate electricity.

An alkaline battery works because of a chemical reaction. The positive terminal is made of manganese dioxide and the negative terminal is made of zinc powder. You can find more information at http://en.wikipedia.org/wiki/Alkaline_ba...
