Super Capacitors/Graphene

By rwsandoval, September 27, 2016

Anyone familiar with Super Capacitors? Has there been any changes regarding energy density and charging time.
Speaking off the top of my head, Graphene is the real thing. Super strong. Super fast heat transfer, has been mixed with Aluminum(Cummins has an engine that uses a mixture of Aluminum & Graphene). The polycrystalline/monocrystalline solar cells are said that their use in solar cells may be usurped by Graphene. Even CPU material may go from silicon to graphene. The heat transfer rate of graphene is much, much faster than Aluminum, such that engines may not need a water pump. Instead heat energy can be transferred into recoverable forms. Engines when compared to electric motors are significantly less efficient. Take 28/29% efficiency number for an engine running at a constant speed to a standard electric motor, 85/90% efficient. A sheet of Graphene could support an Elephant if you could put him on it and secure the ends of the sheet.

Might I suggest that you check out the Graphene-info newsletter found at graphene-info.com? It is a true font of information covering all of the latest developments and uses for the material. It is NOT an investment newsletter, it is completely free and it is establishing itself at the “go-to” place for graphene information. They also sell print and e-book books reporting just abut everything one would want to know about graphene. Using this newsletter, you can identify the latest and greatest uses, develop a solid idea of how large a market that particular product would have and then work backwards… Read more »

Thank you for the newsletter information. I have been interested in the improvement in efficiencies ever since the idea the you cannot get more than 1 as a measurement of efficiency seeped into my mind. You can get 10%, 25%, 90%, efficiency, but the limit is 1. I had met the inventor of the breeder reactor, DeBois Blanc. He tried to tell me that he was getting more than 1. I asked him to explain the result of his process. He had to admit that element that he started with, was not the same as what he finished with. History… Read more »

In your original posting, you made mention of graphene super capacitors. A very good area to research as, unlike more typical supercapacitors that take a bit of time to charge but discharge in a flash, graphene SC’s can charge quicker and discharge slower making them a good storage device for electricity. Another area you might wish to explore is graphene to store hydrogen. I seem to recall research done at Rensselear Poly that resulted in a graphene cell that could store 25% of its weight in hydrogen. At the time, the Department of Defense cutoff for such cells was 15%… Read more »
