[@charlespolk5221]

@@Prof.Megamind.thinks.about.it. Sadoway is advocating for a battery technology not based on solid state physics, so dendrite formation isn't a problem. He started the design process by looking at what the requirements for a grid scale storage battery would be. ie; low cost. Made of abundant materials that are "locally available", safer than exitsing solid state lithium ion batteries, no use of so-called "rare earths". He took as a starting point aluminum smelting which has alumina ore and a separator electrolyte (cryolite) with a carbon electrode placed in an insulated vat. A large current is applied which melts the assemblage, reduces the alumina to aluminum and oxidizes the electrode. The refined aluminum is drawn off. However, if the system was sealed and the heat maintained, the process would be reversible and you would have what was essentially a high temperature storage battery. He then tasked his team with finding other chemistries with better electrical capacity, made of abundant relatively available elements (if you want to make something dirt cheap, make it out of dirt.)

If you read their papers, the big problems have not been the chemistry of the energy storage, but the container. In the early prototypes, the electrical connections were made with expensive precious metals, and as they've tried to develop something less expensive, they've struggled to build a container that won't react with the components (in one version, all the electrolytic salt combined with the ceramic), and can maintain structural integrity and a gas seal through continuous thermal cycling.

Yes, I think the battery itself perfectly works, but there are engineering problems around it. No hard problems, just many. Like handling lots of asymmetric heat expansion cases, or so.

The technology is known for decades, and usual handling problems limit it - dangerous chemicals, heavy metals etc. It is not worse than conventional lead acid batteries but it seems the commercialization attempt was just a mere patent troll. That means they focused on removing it from the market by patenting everything and scaling up the final product so it reaches only "non disruptive" niche markets. God forbid small scale samples sent to universities and hobbyists so they could quickly figure out how to make it cheaper and improve it.

The big thing about LMBs is that they're much simpler to make unlike normal batteries(Tesla's car production is limited by the amount of batteries they produce/buy btw) which means they will scale much faster and there will be no need to transport them far - since most countries could have an LMB factory - that's what Sadoway said himself.

I’ve been waiting for LMB to become commercially viable for some years now. NEC had an agreement with Ambri to use their patented technology, however nothing seemed to come of it. The really exciting thing about LMB is negligible capacity degradation over 10,000s of discharge cycles. This is at least 10x better than Li NMC, and translates directly into a proportional cost reduction per MWhr stored. I’ve not seen a price for Ambri LMB cells, however their websites implies the cost is expected to be ~40% that of Li NMC, which would make it competitive with pumped hydro from a capital cost perspective.

Lithium Iron Phosphate batteries have 10,000 or more cycle lives. Jeff Dahn is testing some sort of lithium battery that is holding capacity to 20,000 cycles.

But consider - Tesla's cell cost, based on Sandy Munro's Model Y teardown review, was just over $100/kWh. On battery day Tesla said they could drop the cost by 56%. Let's round a bit and assume a $50/kWh cell soon coming. And use 20,000 cycles. $50 / 20,000 = $0.0025/kWh stored.

That 200 kWh is a lot of heat. Easy to use to heat your home and bath water! This brings the efficiency more or less to 100%.

Ambri's technology pays off at scale. So that's the irony of the start-up's viability since first articles of the company's products compare unfavorably with commercially available Li-ion offerings. The Ambri technology should be federally funded at the current phase to provide a long run alternative to Li-ion which has difficulty scaling and is subject to materials and production capacity shortages.

@@bromnader5196 Salts can corrode a lot of things., even some ceramics. It does depend on which salts this product is using, and which ceramics, but one thing is for certain; The metal conductors that transfer the power out of the molten metal will have to be some type of electrically conductive material (almost certainly a metal) and it will need to stand up to the salt's very corrosive nature. Many a power projects have failed due to the under estimation of salt's corrosive properties. This is one of the main hurdles holding back the development of molten salt thorium reactors.

Wind farms have a much bigger issue to be dealt with. The majority of them do not have access to the grills they were built to service. I agree this could be a game-changer for that if the cost of production goes down enough to justify access, but that will do little to sell it to the public. The cost of energy will still be high. We need to get the oil companies involved with green energy production on a global scale and ensure they'll have a cut once it becomes feasible. Otherwise, there will always be a war

One of my old students has just sent me the link to this video because about 10 years ago I started basing my university level student projects on the development of a FESS for use in the third world. My brief was that it must require minimal maintenance, it must have high energy density, it should be used for decades - even centuries - with no loss of storage capacity or efficiency, it must be totally sustainable, only require abundant and cheap materials and totally un-toxic to the planet - a challenging brief which only the FESS designs (or mechanical gravity based) designs come anywhere close to fulfilling.

If you listen to Sadoway’s presentations he points out that energy density is not as important for stationary grid storage as are cost and cycle life. Lithium ion is a much better solution for cars and cell phones because of its superior energy density, but for grid storage energy density is less important.

I heard about this back in 2017 and had heard that they were struggling to find the best choice of materials as well as dealing with corrosion from the molten salts, I'm glad they seem to have sorted it out, because grid storage needs something that handles 10's of 1000's of cycles and is safe. This seems to be the ticket. It also takes the pressure off lithium supplies freeing them up for the global vehicle fleet.

I think all the work they currently do is bespoke for now, which is typical of a company at this scale and for a technology that is so new. Whether there are underlying issues in those areas that you noted should be revealed as their project with energos reno makes progress (or not). Ultimately, they have to build it to see if it works, but it seems a commercial partner liked enough of what they saw in private to put their money up for the project to happen.

Thermal cycles are usually problematic because they cause expansion and contraction in solid metal, creating weakness.

Everything that is thought about needs resources. You need to research how much resources are available. For example, I understand we have a decade's worth of industrial sand, used in all technological products and has limited locations you can find it. Areas that are left are in environmentally sensitive areas, so it could be less than 10 years.

[@nicholasavasthi9879]

Calcium is the third most abundant metal on earth, after iron and aluminum. That makes it more abundant than sodium or copper. Antimony is a bit more of an issue. Current production is expected to run out in a few decades. However more caches of antimony have recently been discovered, though they aren’t being tapped yet, so these projections will almost certainly change.

[@MarcoNierop]

The beauty of this Ambri battery is that it IS using abundant materials, readily available on the commodities market, quote from the Ambri website: Available materials The materials inside the system, calcium and antimony, are commonly available as commodities and sourced from multiple locations. Each GWh of Ambri batteries requires less than 1% of current annual production of these anode and cathode materials.

The amortized cost of these batteries will be hundredths of a penny per kWh.
