In May a South Korean group announced a graphene supercapacitor "breakthrough" that could produce very short charging times:
Breakthrough for electric cars: Supercapacitors from miracle substance graphene charges batteries in 4 minutes

And in this older report, a Berkeley group is described as developing graphene batteries: "The Berkeley team is eyeballing the new technology to develop a low cost electric vehicle battery in the 300 mile range, so stay tuned."
Graphene Could Kill Lithium-Ion Batteries | CleanTechnica

I wonder how much of this is hype, and when some of these technologies might make an appearance in cars or even battery products sold directly to the consumer market.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
