Thought I'd share this promising news article. It reminds me of some of the stuff Lasersaber was working towards with his supercaps and graphene. I wonder if we might be able to find a way to replicate this based on the vague details he gives (which I've bolded).

Unfortunately, I can only find it in Italian. Below is my translation.
Enjoy.

"Eternal" battery, the Italian patent
Gianni Lisini, Iuss-Eucentre researcher, has patented a special "eternal" battery, green and currently able to last between 15 and 20 years, but which can be further improved.

In 1799 the Italian Alexander Volta succeeded for the first time in realizing [the invention of] an electric battery, evolving the studies of another compatriot, Luigi Galvani. Today, at a distance of 218 years, another Italian has "reinvented" [the battery], resolving one of the principal problems of this apparatus: its duration [battery life].

Gianni Lisini, Electrical engineer from Voghera and researcher employed by Iuss-Eucentre of Pavia, in fact deposited some years ago a patent for a special battery which has various advantages: above all else it is green, not employing heavy metals, and then it is able to last between 15 and 20 years, even if according to Lisini, with certain arrangements the operating life can be easily further increased.

But how did Lisini succeed in obtaining these results? The battery "is composed of a chemical accumulator joined to a supercapacitor, a condensor of more recent construction, which has the characteristic of being able to accumulate up to 5 million Farads" explains the same Lisini, "with the advantage of having an elevated number of possibilities for charging and discharging, millions versus the few hundreds of the common chemical batteries." The chemical accumulator uses carbon nanotubes, but in reality the work produced by this engineer is more than anything else about the method of putting together these two systems, which on their own constitute nothing new, with the result of "managing them together and deriving an advantage from them both."

Presented at Pisa's Jotto Fair, the "eternal" battery was already realized in various prototypes and, according to Lisini, is already being considered by various agencies, whose names obviously were not revealed. A battery of this kind, as is easy to understand, is very attractive, for example, in the automotive sector, whether for fueling private vehicles or for those involved in public transportation. Furthermore, even if the initial cost is large with respect to current batteries, this can be easily amortized over time, thanks to the longer life which will limit maintenance interventions and in fact will not require special disposal procedures.

Now we only have to wait for further developments in the hopes of seeing it in the future, perhaps in an electric car.

Hi Bob,

Here is Gianni Lisini's patent application on the battery:

Wow, 54 page patent! Looks like someone has done their homework.
