Bio Battery vs Conventional Battery: Key Differences

This page compares Bio battery vs Conventional battery and mentions the difference between Bio battery and Conventional battery.

Bio Battery

Bio battery construction

Following are the features of a Bio-battery:

• Made of layers e.g. anode, cathode, electrolyte and separator.
• Biological enzymes are used for anode and cathode as catalysts. Enzymes and electronic mediators are fixed on both cathode and anode terminals.

Conventional Battery

conventional battery operation

Figure 2 depicts the operation and construction of a conventional battery. As shown, there are three parts in a battery viz. anode, cathode, and electrolyte. Anode and cathode are connected to an electrical circuit or device.

Chemical reactions cause the build-up of electrons in the anode, which results in an electrical difference between the cathode and anode. Electrons try to re-arrange themselves to avoid this difference.

In order to get rid of this difference, electrons repel one another and try to flow towards a place having fewer electrons, which is the cathode. Electrolyte prevents them from flowing directly from anode to cathode in the battery.

As a result, electrons flow from anode to cathode when the circuit is closed (i.e. a wire is connected between cathode and anode). When the electrons flow through the wire, it will light the bulb as shown.

Due to the electro-chemical process, chemicals will change in the anode and cathode. Due to this, they stop the supply of electrons. As a result, a limited amount of power will be left in the battery. This requires us to recharge the battery.

When we re-charge the battery, electro-chemical processes happen in reverse. This will restore the anode and cathode to their initial state and they will deliver the power once again.
