The Telegraph and Stanford News are reporting a new aluminium-ion cell which is hoped will outperform conventional lithium-ion cells.
As well as charging in 60 seconds, it is claimed, the cell will withstand 7,500 charge/discharge cycles compared with lithium-ion's 1,000 cycles.
Apart from a low 2-volt output, "our battery has everything else you'd dream that a battery should have: inexpensive electrodes, good safety, high-speed charging, flexibility and long cycle life," states Hongjie Dai, Professor of chemistry at Stanford University.
"We have developed a rechargeable aluminium battery that may replace existing storage devices, such as alkaline batteries, which are bad for the environment, and lithium-ion batteries, which occasionally burst into flames."
The research is due to be published in Nature.

Not sure why they are down on this [the 2v output]
Megahard's comment led me to re-read TFA and realise it is quite ambiguous - ie it could mean "our battery has everything it should have:- 2 volts and everything else", and that is how I first read it. The idea of a ~2v cell is so to be expected that without thinking I took it to be an advantage. After all, you just stack them up as you say, like a 12v car battery is 6x2v cells, as most people probably do not even realise in these days of sealed units.
Being picky, the 2v unit is a cell, not a battery. The battery is the assembly of cells in series.
As for having dreams about batteries, sounds like Prof Dai should seek help.

You are a windbag and a bore. Be gone.
