Batteries that Recharge in Seconds

A team of researchers from the University of Illinois at Urbana-Champaign have managed to make battery electrodes that can be 90% recharged within 2 minutes. If the method can be commercialised it could lead to laptops that recharge in minutes or mobile phones that can charge in 30 seconds.

The method used to make these ultrafast electrodes is compatible with many different types of batteries and the researchers have also used them to make nickel-metal-hydride batteries, the kind used in hybrid and electric cars.

The rate at which a battery can be charged up is normally limited by how fast ions and electrons can move from one end to the other. The researchers have used a nanostructured materials to try and find a way to decrease recharge time, and have now made progress using a highly porous metal "foam", coated with battery materials.

The method used for making these batteries, although it is complex should be easily applicable for the types of batteries commonly used in laptops and electric cars, and could be found in electrical appliances relatively soon.

  1. Sounds awesome, but how many times will they be rechargebel

  2. Sounds awesome. I remember the days where we had to go buy new batteries or wait about 8 hours before they recharged. lol

  4. @Trolske i think the question is how much maximum charge will they lose each time they recharge

  8. if this gets into the electric car industry, think of what this would do to the electric car industry, especially now with prices soaring...

  9. Also, are these going to be the charge of a standard battery pack? What would be the use of having a batter that charges in two minutes if it can only sustain the battery life of a half hour on a laptop?

    If this can prove to be a reliable battery and have super fast recharge times, then this will be a great way to save electricity since so much won't be wasted.

  10. I know this would totally change the baterias future

    Oh thats rigth! baterias in spanish means battery.

  18. nice, i made the move to rechargeable batteries years ago, and thankfully any amount of time shaved of the recharge time would be welcomed.
