Ionised Air Battery: Can a Potential Difference Exist?

In summary, there are efforts to use radioactivity for direct electricity generation, but managing charge effects in the proximity of a radioactive core can be challenging. Wrapping carbon nano tubes around the core can potentially create a potential difference, but further research is needed to fully understand and utilize this concept.

Radioactive material ionises the air around it.
Carbon nano tubes have an extremely large surface area, & could possibly "store" the ionised charge.
If a volume of carbon nano tubes is wrapped around a core of insulated radioactive material, can a potential difference exist between the wrapping & the core?

Charge effects are challenging to manage, especially within a short radius of a radioactive core.
There have been efforts to harness radioactivity to create electric power directly by using the radiation to excite a phosphor. The emitted light then drives solar cells which produce electric power. The overall efficiency here is not high, but the setup is reasonably safe and robust.

Yes, it is possible for a potential difference to exist between the wrapping of carbon nano tubes and the core of insulated radioactive material. This is because the ionised air around the radioactive material can transfer its charge to the carbon nano tubes, creating a buildup of charge on the surface. This buildup of charge can then create a potential difference between the wrapping and the core. However, it is important to note that the effectiveness of this setup would depend on the specific properties of the carbon nano tubes and the radioactive material, as well as the conditions of the surrounding environment. Further research and experimentation would be needed to determine the feasibility and potential applications of this concept.
 

1. What is an ionised air battery?

An ionised air battery is a type of battery that uses the ionisation of air molecules to create a potential difference, or a flow of electrons, between two electrodes. This potential difference can be used to power electronic devices.

2. How does an ionised air battery work?

An ionised air battery works by using a high voltage source to ionise air molecules between two electrodes. This creates a potential difference between the two electrodes, causing a flow of electrons from one electrode to the other, which can then be used to power a device.

3. Is an ionised air battery safe?

Yes, an ionised air battery is generally considered safe. The high voltage used to ionise the air is usually contained within the battery and poses no risk to the user. However, as with any high voltage device, caution should be taken when handling the battery.

4. What are the advantages of using an ionised air battery?

One advantage of an ionised air battery is that it does not require any external chemicals or materials, making it more environmentally friendly. It also has a potentially longer lifespan compared to traditional batteries, as there are no chemical reactions involved that can degrade the electrodes.

5. Can an ionised air battery be used for large-scale energy storage?

While ionised air batteries have shown promise in small-scale applications, such as powering electronic devices, they are not currently suitable for large-scale energy storage. The technology is still in its early stages and further research and development is needed to make it viable for larger applications.
