Researchers in Massachusetts are working on a new kind of battery. This battery, unlike current ones made of toxic metals like cadmium and lead, is made almost entirely of carbon. Essentially, this means it would just degrade after a time, or they could be incinerated though that risks releasing more carbon into the atmosphere. It would be a completely organic material, carbon, though in this case organic does not refer to being grown naturally. The new batteries would not release the heavy metal residue into the environment that current options release.
Another strength of the new development is the power packed into these much smaller batteries; smaller meaning up to ten times smaller. These smaller batteries however, would put out the same amount of energy as the currently used batteries. This means they will save energy. That may seem like an odd statement, but they really do save energy. They will not leak out energy like the batteries available today do when they are not being used. All those batteries sitting around on shelves leak out valuable energy but the new and smaller ones would do this significantly less or perhaps even not at all. Therefore, they would be saving energy by not letting it escape.
The new nanotechnology batteries operate by using carbon nanotubes. These are small wires that create a lot of energy. They are too small to be seen by the naked eye and can only be observed through a microscope. The wires receive a fuel coating and the resulting reaction involves thermopower waves. These waves move from one end of the battery to the other with the high level of energy needed for the operation of the battery. These new batteries could allow for many new developments in portable technology and energy saving fields.

This is a very interesting concept, smaller, more efficient, even cleaner batteries to replace the ones we use now definitatly needs some looking into. The only downsides to this that I can see it the potential breakdown of the batteries and the cost it would take to construct them out of material that is to small to see with the naked eye. However if they were to find ways to combat these problems then these carbon batteries will open up so many more possibilities in the field of electronics.
