Magnetic 'Spin Battery' Announced

In summary, the article discusses a new concept called "magnetic spin battery" that has been demonstrated in a lab prototype. The researchers were surprised by the results, as the device produced a voltage over a hundred times larger and for a longer period of time than expected. This concept has potential for greater energy storage density than conventional chemical batteries or fuel cells. However, more research is needed to improve its self-discharging time.

Has anybody heard of this concept?

http://www.sciencedaily.com/releases/2009/03/090311162807.htm

Somebody seems to have now actually shown one in practice. A magnetic 'spin battery'.

Can anyone tell me if this thing is supposed to be capable of greater energy storage density than a conventional chemical battery? Is it capable of even having greater energy storage density than a chemical fuel cell?

What kind of energy density should it have, in Wh?

no, it's all voodoo to me. a primer on spin would actually be nice.

So far, the lab prototypes hold up for 10 minutes, or so, before self discharging. I think that's what I read...

"We had anticipated the effect, but the device produced a voltage over a hundred times too big and for tens of minutes, rather than for milliseconds as we had expected,"
 

1. What is a magnetic 'spin battery'?

A magnetic 'spin battery' is a new type of battery that uses the spin of electrons instead of their charge to store and release energy. This technology has the potential to provide longer-lasting and more efficient energy storage solutions.

2. How does a magnetic 'spin battery' work?

A magnetic 'spin battery' works by using a layer of magnets to create a magnetic field that can store and release energy by manipulating the spin of electrons. The electrons' spin can be either 'up' or 'down', and the battery can switch between these states to store and release energy.

3. What are the potential advantages of a magnetic 'spin battery'?

A magnetic 'spin battery' has several potential advantages, including higher energy density, longer lifespan, and faster charging rates compared to traditional batteries. It also has the potential to be more environmentally friendly as it does not rely on rare or toxic materials.

4. Are there any challenges or limitations to implementing magnetic 'spin batteries'?

Yes, there are still some challenges and limitations to implementing magnetic 'spin batteries.' One major challenge is finding materials that can maintain their magnetic properties at room temperature. Additionally, more research and development are needed to improve the efficiency and scalability of this technology.

5. When can we expect to see magnetic 'spin batteries' in commercial use?

It is challenging to predict when magnetic 'spin batteries' will be available for commercial use. While there has been significant progress in research and development, more testing and optimization are needed before this technology can be mass-produced and integrated into consumer products.
