Then I can inform that in 2012 or was it in 2013 MIT had developed a NANO-based battery who only weight 1/20 or 1/30 of a ordinary car battery
and with a capacity who was 30 or 40000 times higher than a ordinary car battery.
Cold or hot this battery perform in splendid in both conditions
And a lot more
Haven't heard so much about it since then, so I don't know if it was dead end or what.
