I thought Graphene batteries were going to be the revolution:<p><a href="http://grapheneenergy.net/" rel="nofollow">http://grapheneenergy.net/</a><p>This was the response from Dileep the CEO/Founder of GrapheneEnergy when I emailed with him, May 2011:<p>"Currently we are projecting lead-acid type energy densities with 1-2M cycles and 1-2sec charge/discharge performance for graphene base supercapacitors. Also, batteries with graphene anodes can be charged 4x faster and have 3-4x higher cycle life. We are in middle of a key commercialization milestone. As soon as we conclude it, there will be press releases."
