Graphene Supercapacitors and Cars

The above URL is the address for an article over the future of supercapacitors in the automobile industry.  It gives a brief account of why supercapacitors haven’t been of any use in cars up until now.  The problem has been that traditional supercapacitors cannot store energy anywhere near as well as lithium-ion batteries.  The drawback of lithium-ion batteries is that they take so long to charge.  At least some portion of the car market is clearly heading in the electric direction.  The charge time is a large hitch in the design of modern electric cars.  Thanks to Graphene, that’s all going to change.  Graphene, a recent development in the technological world, has been experimented with in the Gwangju Institute of Science and Technology in Korea.  The scientists there have managed to produce a graphene battery that has an energy density of 64 watt-hours per kilogram, which is comparable to the 100 to 200 watt-hours of lithium-ion batteries in electric cars today.  The best part is the battery charges in 16 seconds.

The implications of this new technological innovation are staggering.  Another important factor of the research done in Korea is the reliability of their product.  The battery could be charged and recharged over 10,000 times without losing any energy output or storage capability.  Any car that implements this technology will immediately catapult itself to the top of the electric car market.  Not only that, it might shoot itself to near the top of the overall car market.  As gas prices go up, and they eventually will, this battery will be the first of a new generation of transportation technologies.  A charge time for batteries this low is unheard of.  It seems evident to me that this will have a massive impact on the future of the automobile.  All that remains is to wait and see how much of an impact it has.
