Lithium Battery Breakthrough Cuts Charge Time Down to Seconds

Energizer BunnyImagine that you could charge a car battery as quickly as you fill up a tank of gasoline today. Stop imagining –it has become possible. Researchers have developed a new lithium battery technology that can charge and discharge in a matter of seconds.

The journal Nature is reporting that Byoungwoo Kang and Gerbrand Ceder of the Massachusetts Institute of Technology developed a glass-like Lithium mixture for electrodes that allows a charge to be rapidly stored inside of a battery. The battery is designed so that lithium ions move more freely, moving the charge in and out of storage from cathode to electrolyte. The material also retains its capacity through charge cycles.

However, don’t expect laboratory performance at home just yet. Ars Technica has noted that the battery are not entirely compatible with today’s electric grid. For example, a cell phone battery would drawn 360W in ten seconds– for a single charge. Cue the blown circuit breakers.

I’m certain that some happy medium will be reached, and we can all look forward to more advanced batteries in our electronics. This breakthrough eliminates many of the restrictions that today’s batteries place on device manufacturers, and will should lead to more powerful mobile hardware and a greater variety of devices. It’s a big win for consumers and the industry alike.

    …drawn 360W in ten seconds… There is no problem drawing 360 W from a house circuit. This must be incorrectly written.

    Must be amps? Hair dryers draw 1200+ watts.

    Thanks folks. I just read Ars and tohught that it was an interesting point to add. I”ll check in with the researchers for clarification.

    Yea, at 120 V, 360 watts equals 3 Amps per second (I think). Manageable.

    When buying Cellphone Batteries make sure that you are not getting those chinese fakes and knockoffs..:~
