Dry Cell Anode and Cathode

Dry cell battery usually just can use once, after the cell have fully used then disposed and should be change with new one. But now there are rechargeable type that can be recharged several times for example 1000 recharge, after 1000 times charge usually can be charged again and should be changed with new one.

Battery have two poles, positive poles and negative poles. Positive poles or positive electrode is called as cathode and negative poles called as anode. In dry battery each pole contains different kind of metal. In alkaline battery, anode metal is made from manganese dioxide and the metal in the cathode in zinc. For anode and cathode in other batteries can be seen on the table below.

Inside the battery there is a separator to separate anode area and cathode area and there is an electrolyte. Negative electrons will go to cathode in short way but block by electrolyte substance. When we make a circuit to contact anode and cathode then electron will flow through this circuit and we can use this power.
