UK Man Invents Aluminum-Air Battery In His Garage (cleantechnica.com) 212

An anonymous reader quotes a report from CleanTechncia: UK engineer and former Royal Navy officer Trevor Jackson began experimenting with aluminum air batteries at his workshop in the Cornish town of Callington in 2001. At that time, the electrolyte used was extremely caustic and poisonous. After years of experimentation, Jackson devised a new electrolyte -- whose composition is a closely guarded secret -- he says make it possible for his invention to power an electric car for up to 1,500 miles. What happens when it runs out of juice? You replace it with a new one while the old one gets recycled. At the beginning of the electric car era when charging infrastructure was nonexistent, the idea of swapping spent batteries for fully charged new ones was considered feasible. Jackson says such a thing could be the future, with his batteries/fuel cells sold at grocery stores and retail outlets. He says the process of disconnecting the old one and connecting the new one will take about 90 seconds.

[A]n independent evaluation by the UK Trade and Investment agency in 2017 said Jackson's invention was a "very attractive battery" based on "well established'" technology, and that it produced much more energy per kilogram than standard electric vehicle types, according to a report in the Daily Mail. A Tesla Model S can drive up to 370 miles on a single charge. Jackson says if you drove the same car with an aluminum-air cell that weighed the same as the Tesla's lithium-ion battery, it would have a range of 2,700 miles. Aluminum-air cells also take up less space. If that same Tesla were fitted with an aluminum-air fuel cell the same size as its current battery, it could run non-stop for 1,500 miles.
The report goes on to say that Jackson just signed a multi-million dollar deal with Austin Electric, which will begin putting thousands of the batteries into electric vehicles next year.

"Austin Electric has three targets for the new batteries -- the three-wheeled tuk-tuks used for transportation in many countries such as Pakistan, electric bicycles with far more range than current models, and a program that will convert front wheel drive cars with internal combustion engines into hybrids by fitting aluminum-air batteries and motors to drive the rear wheels," reports CleanTechnica. "Jackson expects the conversion operation to start next year. He says the cost of each conversion will be [...] about $4,000."

        Until the 1890s, the usual spelling in America was also "aluminium". In 1891, Chemical Section of the American Association for the Advancement of Science made a number of recommendations for changes in spelling, including "aluminum" and "sulfur". By 1910, "aluminum" was twice as common as "aluminium", as can be seen here: https://books.google.com/ngram... [google.com]

          Aluminum was also more common in the US from the 1830s until the 1840s, and was more common in the UK from the start up until the mid 1850s.

          I'd also point out that "aluminium" is malformed. It's named after alumina, not aluminia. And there were plenty of "-um" elements at and around the time that could be pointed to (for example, platinum, molybdenum, tantalum, lanthanum). The insistence on everything ending with "-ium" is a later invention not present in early naming schemes. Originally the "i" generally came from the root word - for example, "magnesia" -> "magnesium". It wasn't part of the suffix. Some "i"s also got copied from other elements - for example, selenium was similar to tellurium, so they changed the root "tellus" (earth) to "selene" (moon). The number of elements that ended up with an attached "i" led to the later tradition of deliberately trying to ensure that they all ended up with "-ium", even if the root lacked an i - which was starting to take hold around Davy's time.

          Regardless, I'm a purist; I stick with the original "alumium". ;) Hey, Icelandic shortens it even more, to "ál" ;)

        Since it is a closely guarded secret it is not patented either, and probably not patentable as it is a known electrolyte. The same numbers were touted by Elon Musk for alu/air battery in Teslas only half a year ago too. They forget to mention you need to run electrolysis on the alu to convert it back from oxide though, and that is a bit more hefty than just recharging.

          It's not even "his invention". Alumium air batteries [wikipedia.org] have been around for ages. Great energy density. Everything else, not so much. Including not being rechargeable. To "recharge" them you have to re-smelt the alumina, at significant expense and loss of round-trip efficiency.

            I could also add: there's about 1,5kg of CO2 emitted per kg of alumium produced. A gasoline car that does 6l/100kg emits 13,9kg of CO2 per 100km. A 250Wh/mi EV with a 1300Wh/kg Al-air battery - if its mass were 100% alumium that had to be recycled - would be 28,8kg of CO2 emissions. Now, I'm sure that the whole mass doesn't need to be recycled, but still, any meaningful fraction means a lot of CO2 emissions. The net reaction for alumium production is:

            2 Al2O3 + 3 C 4 Al + 3 CO2

          It doesn't sound very practical. Having to swap your battery every 1500 or 2000 miles seems like it would be quite annoying. You would have to go out of your way to a special location and I'm guessing it wouldn't be all that cheap.

          Electricity is everywhere, it's much easier to just plug in right where you park and have a full charge next time you head out. For long distances a 20-30 minute charge every few hours is no real bother, and actually for commercial drivers the law says they have to have a break more often than that anyway.

    Aluminum air batteries have great capacity, but they're single use, like duracell alkaline AA batteries. When they are done, you take them out and throw them away. Aluminum air batteries have existed for a long time. They're quite simple.
     
    Tesla lithium-ion batteries, when they are dead, you charge them and they're ready to go with 99% of the original capacity, for many recharge cycles. If you can't recharge the battery, it's mostly useless in the modern economy.

      So there are a lot of shortcomings in this, *but* if the economics were hypothetically good, changing out a battery pack once a month wouldn't be too bad if the process/equipmennt is good enough.

      Of course they are claiming operating costs at a touch under petrol cost, and even factoring in wearing out a Li-Ion battery it's more expensive than the energy+battery cost of those. This may be interesting for planes and drones, but it's difficult to imagine it being relevant to the auto industry.

        Somewhere without cheap charging might be a good fit. Places like the far north where electricity is supplied by diesel at 90 cents a kw/h and if the one barge trip is missed, has to be flown in. Other rural areas may be similar.

          And how do the new batteries get there? I'll bet they're no easier to transport than diesel, and their price would skyrocket in those locations. Also the diesel only has to be shipped one way, the used batteries have to be shipped back increasing the cost. Also those are locations where the infrastructure to do the swaps is likely lacking as well.

          There may be an application for these batteries, but they've been around a long time and nobody has found the application yet, and I can guarantee you that cars a

      Worse, cant top off people will have to replace batteries with 5-10% just to be sure they wont get stranded.

        Throw in a small rechargeable battery too. Handy for regenerative braking and could be topped up and give 25-50 miles range.

      • Worse, cant top off people will have to replace batteries with 5-10% just to be sure they wont get stranded.

        You could address that by including a smaller rechargeable Li-ion battery. That battery could also be used for regenerative braking in normal operation, then it could act as the reserve when the aluminum air battery is depleted. You could also address the by putting multiple smaller aluminum air batteries in the vehicle and arranging to use them sequentially. When you get down to your last battery, you replace the others. Multiple small batteries would also help you keep the individual battery weight dow

    • In the "Tesla" context, these might be handy as cheap secondary batteries with ~200-300 miles range, and a per-mile usage cost that's on par with the cost of 92-octane premium unleaded (ie, more expensive than normal operation... but not SO outrageous that you'd never use it unless it were a matter of life or death). The car could ship with the electronics in place and an empty bay, and leave it up to you to use it or not. If your primary (rechargable) battery ran out while driving around town, it would swi

    • LOL "Tesla" batteries. As if Tesla batteries are any different than other batteries.

  • Aluminum is incredibly wasteful in electricity, heat, carbon and fluorine in it's production
    . How is he going to recharge the aluminum without burning carbon anodes to CO2 and melting the aluminum in cryolyte at 940 degrees C? How does he deal with reducing the production of carbon monoxide and CF4, which is a potent greenhouse gas?
    I doubt he has doing anything towards reducing aluminum, only oxidizing it. The article completely ignores reduction.
    • Aluminum is incredibly wasteful in electricity, heat, carbon and fluorine in it's production

      Yeah, but it's a lot cheaper to recycle than steel, because it melts at such a lower temperature, and because it retains its properties through the process. For structural metal (like, say, auto body) aluminum breaks even (by comparison to steel) once you recycle it just once.

      How is he going to recharge the aluminum without burning carbon anodes to CO2

      Now that's a good question.

    • by Junta ( 36770 )

      Yeah, that is what bothers me about the article.

      'This battery uses aluminum, and aluminum can be recycled', glossing over the whole fact that 'easy aluminum recycling' doesn't require reducing it.

      I mean it's nice to have non-toxic components, but not touching on how to reverse the reaction is problematic.

      Also whether it solves that battery types self-discharge problems.

      There are a lot of downsides, though I could see how the weight-density could make it appealing for at least some more aircraft than LiOn to

      One of the big aluminum producers is deploying aluminum smelters that don't emit CO2. I don't think there's anything magic about using carbon electrodes, it's probably done because replacing the electrodes and emitting CO2 is easier than dealing with hot oxygen.

  • I note this 2002 paper (got from 2 seconds googling via wikipedia) https://ui.adsabs.harvard.edu/... [harvard.edu]
  • From the fine article:

    Everyone knows that if we are really going to hit the Governmentâ(TM)s target of net zero greenhouse gas emissions by 2050, the hardest nut to crack is transport.

    We cracked that nut already.

    This is a demonstration plant that produces carbon neutral hydrocarbon fuels, carbon neutral because it takes CO2 from the air to make the fuel and close the loop on CO2 in the air.

      sure we did, ever notice how these "demonstration plants" never make it to the big time, shit, a hundred years and we're still burning coal and hydrocarbons, and you people really think it's just going to suddenly get better ... sure buddy, keep dreaming

        Nothing is suddenly going to get better, which should be clear to anyone that thought this out like I have. I'll explain how I came to this conclusion.

        The typical lifespan of large hydrocarbon burning machines is on the order of decades. For a typical passenger car they last about 10 years before considered worn out, considered a loss in some kind of collision or accident, or whatever. A large truck, such as a semi tractor, will be on the road for 15 years. Specialty vehicles that aren't run as often, l

    • by jemmyw ( 624065 )
      I read that the hardest nut to crack is industrial heat, i.e. the production of steel, ceramic and cement. These processes need high heat in very specific ways that make it hard to replace with non-fossil fuel, plus some of the processes require the carbon from the fuel to work. These industries emit more CO2 than transport, and they're harder to tax as they are not consumer facing, and often have national security and trade implications.
    • LOL. You are nuts. "carbon neutral hydrocarbon fuels". Christ. People really are getting dumber.

    If these batteries can really hold enough energy to power a car for 1500 miles, I look forward to the YouTube videos of people dropping a crowbar across the terminals.
  • Why not just shred the aluminum, burn it in a boiler and run a steam engine off of it. Refuel with another bale of shredded Al. and empty out the ash from time to time.

Every nonzero finite dimensional inner product space has an orthonormal basis. It makes sense, when you don't think about it.
