I read the abstract and have very little idea what is going on. Summarize it for those of us who dated in high school.
Trait; Lithium-air:Lithium-ion Electron-transfer efficiency; 15:1 Storage capacity; 3:1 (Eventual) Cost of goods; 1:10 Safety; Solid metal and ceramic, no liquid: known safety risk Scalability; 1000:1? This is hard to quantify, but a solid-gas composition vs solid-liquid-gas is...just wow.
Interesting. Seems like a big deal. How would this compare to SS battery tech that Nissan said they’ll roll out by 2028?
You can't swing a dead cat without hitting a dozen bench level chemistry break thrus. This could be the one, but there's a long way to go and a lot to consider as it goes from bench to pilot to automated production.
This one's different. Softbank and others are already invested and financing scale-up/implementation. Don't be surprised when a better electric car comes out of both China and the US. IP battle will play out.
Could be. I definitely believe there will be great gains in battery chemistry and I root for them all. I don't mean to pooh-pooh this, I'm just pointing out that there are many funded breakthroughs happening all the time.
True that. But, removing liquid from lithium batteries is on a fundamentally different level of tech accelerant from both an investment and scientific perspective.
Agree. What is possible is often extremely difficult to make economically feasible. Hope the research continues to progress
Not in this case. Scale-up is far, far easier for solid-state. Look at laptop memory drives, for example. The move from mechanical drive to solid state changed that market.
There are a lot of benefits to solid state batteries, one of the biggest is removing the creation of dendrites which have significant negative impacts, as well as improved density, but I don't see this as a fair comparison. Scale up was easier for SSHD because of the removal of a lot of moving parts and their associative hardware. Here we're just talking about replacing a liquid electrolyte with a solid. This doesn't remove excessive complexity the way the move away from spinning drives did.
Sure it does! Removing the requirement to (safely and efficiently) store liquid has enormous implications!
Less reliance on rare minerals, superior storage density, and resultant weight decrease meaning lower impact on range and more forgiving accidents. Wins all around. I don’t think the liquid vs solid state plays much of a beneficial role if just looking at the inherent state of the naturals.
I’m referring to total manufacturing cost, not just cost of materials. Like I said, I hope the research continues to progress but right now this is a technology that has quite a ways to go before it can be successfully and feasibly produced.
nanocracks in ceramic coatings identified as reason for failure in lithium metal batteries. another step in making them work Scientists Find the Holy Grail: the Reason Why Lithium-Metal Batteries Fail (msn.com) When looking for an anode material for your next-gen battery, you can’t do much better than lithium metal. Due to its high capacity, low density, and non-flammability, lithium-metal batteries could be an absolute game changer for electric vehicles and the green tech revolution at large. There’s just one problem: Lithium-metal batteries have a tendency to short circuit thanks to tiny fissures in the ceramic electrolyte called dendrites. .............. “Just modest indentation, bending or twisting of the batteries can cause nanoscopic fissures in the materials to open and lithium to intrude into the solid electrolyte causing it to short circuit,” lead coauthor William Chueh says in a statement. “Even dust or other impurities introduced in manufacturing can generate enough stress to cause failure.” ................ Now that researchers have convincingly answered the question of why, the overall question of lithium metal’s future is looking less like “if” and more like “when.”
