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.

  No figure was given in the video or write-up, even though positive comments were made pertaining to that aspect. Sounds like the techniology has potential - let's see a Tesla packed full of these, as that's the field where I think batteries are still massively lacking. Even if their no good for automotive, grid-scale storage is another field that's desperate for improvements.

  > charging in 60 seconds

  If it self-discharges in a week, I don't want it. The aforementioned Tesla already needs a significant amount of juice to stay topped off overnight.

    But even if it does discharge in a week, you can still have it filled in less time than grabbing a coffee.

    ie: it isn't relevant anymore. Or atleast it depends on the application. It's irrelevant if we talk cars or phones.

      Charging a Tesla-like car battery in 60 seconds would suck so much energy from your home wiring that it could even start a fire.

        Thanks for the headsup. That's even more awesome than I antcipated ;)

      It's relevant because I pay for every charge. I pay for the overnight losses, and some power company has to burn something to produce the juice.
      It's also highly relevant if I want to leave the car at the airport during a trip.
