OK.
But WHEN are we going to see new batteries?
If I got paid 2 cents for every battery breakthrough I have read about in the past 10 years, I would have enough money to buy a new battery.
It is just not happening, whether it be super-capacitors, or graphene or 3d batteries or single molecule thick, I still sit with
Nicd or NiMH batteries in everything, and they are no more useful than a black Eveready cell from Spar?
LED technology is about the only thing coming to market, that has improved some aspects of battery usage.
