    Just like with all of these headlines, it will not charge in seconds outside the lab without cryogenic cooling systems. Pack density is already largely limited by cooling systems, so everyone looking for faster charging and higher range should really be focused on superconducting tech more than cell chemistry

    However, this technology does not yet match the energy density of lithium-ion batteries.

    It would be good if you actually told us what that energy density is…

      Two important parts of a battery are how much energy it can store in a certain space and how much it weighs. If it is bigger and holds the same amount of energy that might be ok for a non mobile storage if it costs less, like a house. If it weighs more for a certain energy that wouldn’t be useful for cars and mobile things but might be ok for small things where the weight is negligible anyway. For cars you want a small energy dense battery that is light as possible

      Abstract

      Downsizing metal nanoparticles into nanoclusters and single atoms represents a transformative approach to maximizing atom utilization efficiency for energy applications. Herein, a bovine serum albumin-templated synthetic strategy is developed to fabricate iron and nickel nanoclusters, which are subsequently hydrothermally composited with graphene oxide. Through KOH-catalyzed pyrolysis, the downsized metal nanoclusters and single atoms are embedded in a hierarchically porous protein/graphene-derived carbonaceous aerogel framework. The carbon-supported Fe subnanoclusters (FeSNC) as the negative electrode and Ni subnanoclusters (NiSNC) as the positive electrode exhibit remarkable specific capacitance (capacity) values of 373 F g−1 (93 mAh g−1) and 1125 F g−1 (101 mAh g−1) at 1.0 A g−1, respectively. Assembled into a supercapacitor-battery hybrid configuration, the device achieves an excellent specific energy (47 W h kg−1) and superior specific power (18 kW kg−1), while maintaining outstanding cycling stability of over 12 000 cycles. Moreover, FeSNCs displayed a significantly reduced oxygen evolution overpotential (η10 = 270 mV), outperforming the RuO2 benchmark (η10 = 328 mV). Molecular dynamics simulations, coupled with density functional theory calculations, offer insights into the dynamic behavior and electronic properties of these materials. This work underscores the immense potential of metallic subnanoclusters for advancing next-generation energy storage and conversion technologies.

      Article says 47 Wh/kg. Thats around a third of LFP cells. But the power density is way higher. Meaning it can do enormous peak currents.

      For grid energy storage, energy density is not the most important factor, but the power density is a great plus. It means these cells can rapidly charge or discharge in the grid, offering flexibility to buffer in any way that is required. And the cycle life is also way higher.

        UPS batteries need to be fully charged all the time. Lead acid batteries like to be fully charged. Lithium batteries need to be stored around 50% charge to have a long lifetime.

              It makes sense to me to have low power chargers on a UPS. Once your power comes back online, it needs to deliver enough juice to power everything plugged into the UPS plus the battery charger. A fast charger would be more likely to trip a breaker.

          This is theoretically something sodium batteries would be good at right?

          Aren’t they not as sensitive to storage voltages? They are almost a perfect lead-acid replacement. Plus a UPS is a great usecase because it doesn’t matter if it is 33% bigger to achieve the same capacity.

        There are newer LFP portable batteries with <10ms UPS switch times that charge quickly and have much longer battery life’s (3000+ cycles), and LFP cells don’t degrade the same when kept at 100% like other types, although you should still cycle them a few times a year.

        Bluetti makes some, the elite series has their latest UPS features. The non elite are slower and noisier.

      NIckel Iron is fantastic without any revolutionary improvements. Batteries made 100 years ago still work today. They are large and heavy so are only of use for home power.

      The big “down side” which is the reason it isn’t commercially developed at large scale is that they last forever. No investors are going to give billions to a business that can’t generate revenue forever with a product that needs replacing every 3 years.

          They are large and heavy. They are only useful for their virtually infinite life. If the military needed it for a few of their bases, they’d contract it out, a few hundred would be built and that’s it.

          For example a few thousand ISDN adapters were built for the government military. But it lacked corporate support because the Telcos didn’t want it cutting into their profits. So ISDN barely existed for consumers. Consumers suffered with 56k modems for 5-10 years until broadband- which telcos sold for more than a phone line, were immune from all the competition requirements of regular phone lines, plus got TV programming profit.

    this is one of the bigger changes in battery tech i’ve read in a while. i’m curious about their beef aerogel tho. i have no personal problem using it (beef is going to be used, regardless, so ethically we should not waste the beef we’re producing) but i would love to see this battery tech become vegan. in part so i can calm the little part of my conscious, and in part so we don’t have to have an ethical debate about batteries.

      Per the article they are working on that, which is good since cattle farming is not exactly eco friendly.

      The researchers are currently investigating the use of other metals with this nanocluster fabrication technique. They are also testing natural polymers as more abundant replacements for bovine proteins to facilitate potential manufacturing.

      It takes decades for innovative products, or seemingly useless ideas, to be commercially viable. That’s why the best response, when asked what is the purpose of doing research on seemingly useless topics, is to say “I don’t know, but I know it’s going to be taxed someday.”

    Team expects, may be useful, could be used, prototype, are currently investigating and so on. Cool piece of technolgy, but no even mention when they’d expect that to be commercially available, if it’s even possible to manufacture in commercial scale. Like many other new battery chemistries and technologies, it shows promise and makes a good headline, but at this point that’s pretty much it.

      To be fair, commercial long-life nickel-iron batteries are already being sold for grid storage. The main reason they aren’t used more widely is they cost more up front.

      That’s ok, because they still cost less than alternatives over the full life span of the battery.

      The risk is that the higher purchase cost required will likely be wasted as new battery tech surpasses it long before its life is over.

      So for now, it’s all about weighing opportunity cost, tech lock-in, and early obsolescence

    The technology uses nickel and iron clusters smaller than 5 nanometers, meaning 10,000 to 20,000 clusters could fit within the width of a human hair.

    By using these dimensions, the researchers increased the electrode surface area, allowing almost every atom to participate in the chemical reaction. This efficiency enables the battery to reach a full charge in seconds rather than the seven hours required by historical versions of the technology.
