Tear down of Zinc Carbon Battery - Eveready 1.5 volts

Just for curiosity sake - I've opened up a dead Zinc Carbon battery 1.5 volts made by eveready. What it made off seems look very simple but as you know it eveready batteries are among the worst charged batteries. The charged usually drain out faster if compared with standard 1.5 volts Energizer batteries and the amperage of current is not so strong either. We can test this on various home electronic devices such as flashlights, electronic shaver, hair trimmer it will drain that battery fast and the current it provides can be feel on devices performances.

Anyway i am tearing down this battery and let's take a look what's inside. If you intend to do the same please use safety gear especially hand gloves before doing this to prevent unnecessary injuries from the chemical compounds of carbon inside the battery. So this is the battery after opened up.

I am keeping the carbon compound and the carbon rod for future use. We can make sample battery out of this thing



The standing cylinder thing is the carbon electrode wrapped by paper. The paper can absorb liquid to allow electron move from the carbon to the zinc to form zinc oxide. The carbon is the anode (positively charged) terminal. I am not sure what is the electrolyte being used in this battery but you can research it on Google to get more info. The torn strip shorter cylinder next to the carbon with the black thing on it is the zinc (negative terminal) - the black thing is possibly the residue of carbon resulted from electron movement from the carbon when electric current is generated. The black plus the zinc is called zinc oxide i think. When the zinc is fully populated and completely oxidized by the carbon that's the end of electron movement and no more electricity is supplied from the carbon. You can throw away the battery when that is done. The shiny metal is the outer protective casing of the battery. I've read somewhere energy cannot be destroyed it can only be transferred. This is important to know.
