Someone is really bad at math... substance with 8.6Wh/g yields only 1.2Wh/g (~14%), then takes 15Wh/g (12500%) to get back to the start. That's an overall 8% efficiency. That's total crap! Li-ion might be 1/6th the _usable_ energy density, but it doesn't take 12.5 times as much energy to recharge it. Unless you have a super-secret, uber-efficient method to produce aluminium, this is all just madness. "Buring" AL is just crazy. The expense (and pollution) of generating it is why we're so keen on recycling what's already processed. Hydrogen is a better storage medium, and water is very hard to break apart. (yes, the fuel cell is rather expensive, but I'm not recycling it every 1000km) Saying "zero emission _vehicle"_ is infinitely misleading. Sure, the car doesn't spew anything, but recycling the sludge out of the battery _sure as [censored] does._ (I can't speak about India, but in the US, car batteries [lead and lithium] get reused/recycled. Yes, cellphone/laptop/tool batteries just get tossed in the trash, because people don't know any better, and can't be bothered.)

The efficiency of this battery is more similar to H2 fuel cell efficiency, as it takes 15 kwh of electricity to produce 1kg of Aluminium, but that 1 kg will only give 1.2 kwh of electricity for the car. This is grossly inefficient compared with lithium ion batteries. Also, the aluminium air battery becomes heavier as it reacts with o2 (43kg anode becomes 125kg alumina). This alumina must have a significantly greater volume than the aluminium, requiring the removal of alumina sludge every 300 km's. I like the idea though and there will no doubt be some suitable applications.
@a1nd23

This actually sounds very appealing. Regarding your points: 1. the car does not have to have 1000-km range battery. Most people would be happy with half of that. That would lower the weight of the anode to 20 kgs. Further - why would you have to replace the anode in one piece? It could be 4 smaller batteries, each with an anode of just 5 kgs each. You could replace as many anodes as you want at one stop (like you don't have to put the full tank of gas in a gasoline car). 2. the energy used to make aluminum - the question is not how much energy it takes to make the anode, but what % of the energy spent on creating the aluminium is used to move the car. Aluminum is the fuel here. You spend energy to separate it from oxygen and then you recover the energy when it re-combines with oxygen. So you use energy (wind / solar / fossil fuel) in a power plant, and then this energy - converted to electricity - is used to move the car. Tesla uses this electricity to recharge the lithium battery. Aluminum factory uses this energy to separate aluminum from aluminum oxide. So the question is - given 1kWh of energy at the source how much energy can be used for moving the car? Exact calculation can be done, but using the cost calculation - it should be quite an efficient process. 3. Regarding refueling the car with the water and removing aluminum oxide - it can be done with a specialized pump. You just pull up to a refueling station, plug-in the pump, and it would do all the hard work.

The limitations you speak of can be overcome by design. e.g. The 43kg Al plate could be designed as multiple plates or rods. e.g. 1. Nuclear reactor uses rods, 2. 4 plates = 10kg each mounted side by side. The water change can also be made via a double tank insertion, one always in reserve so not interval dependant with automatic switch over. Then there is the Al Oxide residue. If this could be removed by slumping into a sludge tank it would keep the electrolyte fresh at all times. The sludge tank could then be changed over when the duplicate water tank is changed. They could even be made as a dual water/sludge tank module.These mods come close to a home swap sequence.

You're talking about nonrechargeable batteries, essentially. When swapped, they have to be remanufactured. So instead of moving electricity to the car, we're moving batteries from the manufacturing facility to the car. discharging the batteries, then moving them back to the manufacturing facility to restore them to serviceability/full state of charge. I don't think you captured all of the costs per kilometer for the end user. Aluminum isn't very expensive, but battery swapping facilities are, and so is all of that material hauling between customer and manufacturer. Very capital-intensive, lots of moving parts, lots of maintenance and energy costs. When you spoke of disadvantages of metal-air batteries, you did not mention contaminants, which can get into the battery via water *and* air. I don't think there will be any way for metal-air batteries - nonrechargeable - to compete with L-ion. Rechargeable batteries, where only the electricity has to be moved around, is going to beat it hands down for cost and convenience.

From her numbers 1 kg of Al stores 4kwh of energy, and needs 12-15 kwh to reprocess the Al Oxide back to Aluminum. So we have a 25-33% efficiency, similar to H2 for the full cycle. Al is simpler to store than high pressurized H2. But it gets heavier compared to Hydrogen the bigger the H2 tank can get.

It's a great idea, but people (in general) hate wasting their time at service stations. Current EV "long charging times" only apply to those who exceed the maximum available range. When used within max range there is no waiting time. You arrive at work, charge your car while exercising your job and afterwards you can go home. Do some grocery shopping and charge your car while sleeping to find it fully charged the next day. The refilling of water is not required. There are systems that will do this automatically. Real potential can be acquired If they can achieve a 15.000 km distance before servicing. Great work and take care ✌️

What is needed is a reconfiguration of the battery into two parts such that when one is exhausted, the second one cuts in. Then we need a system in which you can slot in the new Al anode by yourself. Each one would weigh about 21kg, well within the capacity of most anyone. A little light on the dash board tells you when one is finished and you have switched to the second. You have 500km until you must swap out the anode in the exhausted one. We could even have two batteries which are a quarter of the size proposed. Each one gives you 250km. The weight which must be changed would be 11kg. Even more feasible. Even four 11kg batteries could be used - all in one package.

Wonderful work sira! Long waited for this one. However, there's a down-side to this kind of battery that I think is suspiciously kept under wraps. Namely that the very caustic KOH electrolyte - continues to eat-up the Aluminium anode even when there's no current in the external circuit. This is a serious hurdle as it means that it would be wasteful to merely keep the vehicle idle! One approach has been to "stop" the cell reaction by moving the electrolyte out & isolating the aluminium with lube-oil. Did you see how Phinergy/e-9 work their way around this?

To qualify as saying it would have a 1000km range you would need to include the extra weight of 2-3 water swaps worth of water, a device that pumps new water in, a storage tank for alumina solution, and a device that pulls the sludge out. This would keep the battery running optimally but add a lot of weight ... possibly detracting from that 1000km range. I think this application makes more sense for electric airplanes (EAs) as the cathode replacement and maintenance equipment will be a niche infrastructure to start and isolating it at airports would be easy.

“Lithium Ion batteries end up in land fill 98% of the time” just shot her credibility right there. While laptop batteries end up in land fill, there is so much value in car batteries that 98+% will be recylced after the end of their 20 to 40 year life. By not talking about what is likely to happen with EV batteries, she makes a disingenuous statement that casts doubt on everything else she said. No one wants to mess with installing batteries when in 10 years off peak excess Renewable energy might be $0.01 per kWh with means 60 cents to fill up your Model 3. Additionally EV will be needed enmasse to drawn down excessive peak during low demand. Better would be to allow EVs to charge for free or even get paid to suck energy off the grid when it peaks.

In this current moment in the US, Cars are the *only* industry that recycles them, unless you count buying used cells off Ebay for projects and ebike packs. People chuck electronics in the bin all the time, and have for years. EVs have only been cheap for the last 5 years or so, so their impact hasn't had a chance to change much. Actually Recycling in the US is garbage in general, what 'Recycling' we do have often amounts to 'put it on a boat to a 'reprocessing' center overseas so they can dump it into the ocean without us being the ones to look bad'.

@@DFX2KX Indeed, even in States that promote EVs, such as WA, recycling is often one single recycling bin where everything is mixed up, glass, paper, etc., but batteries are not allowed. This garbage, recyclable or not, is not shipping overseas anymore, as China has been refusing recycling garbage for several years now, for obvious health and pollution reasons, so States need to process it locally. Most States didn't have time to develop recycling centers of their own before the scrap policy changed, so sometimes, less recyclable stuff has been collected and more land-filled or burned. Anyway, another example of liberal Disunited States of America, each State setting their own standards and policies because recycling in Arizona _must_ be different from recycling in Oklahoma for whatever insane politician reasons, and I am not sure there to which of the two words does "insane" applies...
