I've lost count of the number of stories I've read over the years about awesome advances in battery technology that will increase battery capacity two fold, ten fold or in this case so many fold that a battery a few square millimetres in size could start a car.
What I want to know is: what happened to 'em?
Coz they all say they'll be on the market in 5 years, I've been reading about them for 10 years but my phone battery still only lasts a day
