‘Superbattery’ can charge much faster and never explodes

The battery can be made from ‘earth-friendly materials’ like sodium, which can be extracted from seawater.

A new longer-lasting battery technology that can’t catch fire has been developed by a team of engineers led by 94-year-old Professor John Goodenough, the co-inventor of the lithium-ion battery, the Daily Mail Online reports.

Lithium-ion batteries are one of the most popular types of rechargeable batteries used in many mobile devices, but they can sometimes explode and catch fire – as was the case for Samsung’s Galaxy 7 exploding battery fiasco.

But this new battery technology could increase the distance electric cars can drive for between charges, and recharge within minutes rather than hours.

The new battery technology could be used for mobile devices, electric cars and stationary energy storage. It was developed with Dr Maria Helena Braga, a senior research fellow at the Cockrell School of Engineering at The University of Texas at Austin.

The battery is low-cost, all-solid state and noncombustible. It has a long cycle life (battery life) and charges and discharges rapidly.

‘Cost, safety, energy density, rates of charge and discharge and cycle life are critical for battery-driven cars to be more widely adopted,’ Professor Goodenough said.

    A different battery claims to be suitable for renewables.

    ‘Researchers at The City College of New York-based CUNY Energy Institute announce the development of a novel low cost, rechargeable, high energy density battery that makes the widespread use of solar and wind power possible in the future. It is based on manganese dioxide (MnO2), an abundant, safe and non-toxic material.’

    Unfortunately, no details are provided. This would be the first major achievement for the City College.

  3. Stephen Richards says:

    Another one that requires lots of energy to fabricate. No use without nuclear.

  4. oldbrew says:

    George – the DM report has some other details e.g:

    ‘But this new battery has glass electrolytes inside it instead of liquid ones, enabling the researchers to use an alkali-metal anode which doesn’t form dendrites.’

    Using an alkali-metal anode (lithium, sodium or potassium) delivers a long battery cycle life – in experiments, the the new batteries demonstrated 1,200 cycles with low cell resistance.

    The battery can also operate at very cold temperatures of -20 degrees Celsius (-4 degrees Fahrenheit), so it could perform well in a car in freezing conditions.

    It’s the first solid-state battery (meaning it has solid electrodes and solid electrolytes) that can function at temperatures below 60 degrees Celsius (140 degrees Fahrenheit). ‘

  5. oldbrew says:

    Carmakers are betting that the day of the electric car is coming, in part because of government emission limits and concerns about air quality in cities around the world. And battery capacity keeps improving. But the tipping point where large numbers of people opt for a car you have to plug in remains several years off at the very least.

    And then the national electricity consumption also accelerates, while fuel duty income for the Treasury takes a dive.

    all the way down to -4 Fahrenheit? wow, that’ll really work well in Minnesota and North Dakota where it often gets down to -25 or so. /snark

    Sodium – ‘earth-friendly’, non-combustible? Sure, sodium chloride (table salt) is non-combustible, but put in on your garden and goodbye crops. OTOH I was shown in high school science that pure sodium is pretty nasty and flammable. So what form of sodium does this battery use?

  8. Graeme No.3 says:

    Obviously sodium metal to get the electricity. Originally made from ? (certainly not sea water, perhaps molten salt?) with lots of electricity. No problem there as we all that wind turbines generate all the time. To copy stpaulchuck snark/

    It’s a slow burning story this one. Here’s a paper discussing progress in glass electrolytes, from 2006….

  11. hunter says:

    I doubt it. Sodium burns in water nearly as well as Lithium. And rapid charging means rapid heat buildup.

    Imaging the inner workings of a sodium-metal sulfide battery for first time
    March 6, 2017

    This study represents the first time that researchers have captured the structural and chemical evolution of a sodium-metal sulfide battery during its electrochemical reactions.

    “Our full-field hard x-ray transmission microscope was critical because it provided nanoscale spatial resolution and a large field of view. Other microscopes typically provide one or the other but not both,” said Wang.

    Yeh I’ll believe it when I see it.
    People make claims.
    This one has not been independently shown nor tested.

  14. Gamecock says:

    Another super battery!


    ‘In the short term they hope to work with battery manufacturers to test the battery in electric vehicles and energy storage devices.’

    Get your headline now, before testing is done!

  15. oldbrew says:

    The financial test could be the toughest one.

  16. Harry Passfield says:

    @oldbrew: Fuel duty taking a dive? Another reason for smart meters: They’ll know when a car is being charged and price the electricity accordingly. Any bets?

  17. oldbrew says:

    Road use pricing would be my bet.

    I’d also bet on different tariff options like they have already in some US States. A bit like 1st and 2nd class post, except for electricity supply. Agree to have some of your appliances remotely switched off at times of ‘system stress’ and get a cheaper rate – that kind of thing.

  18. oldbrew says:

    From Gamecock’s link:
    “Let’s remember that the need for energy storage systems is strictly a consequence of the intermittency of renewable energy sources like solar and wind,” Yeatman said. “… These companies benefit from the grants and indirectly from the inefficiencies of an industry that exists by the grace of political favoritism.”

    Trying to fix a problem that doesn’t need to exist.

    I doubt something like this would ever go public, low battery life is the cornerstone of a thriving market. If they make faster charging, longer lasting batteries, where is the money in that?
