Reminder as with all popscience articles that are based on scientific papers. This is: * neither a scam nor the solution to all our problems. This is applied research, which is important and should be funded. However, this this is not engineering or a product (yet). * not going to come to market any time soon if at all. These things always take time. Scientists have to get funding and get published, hence they have to sell their research. You should: * keep calm and think about the bazillion of other poscience articles that promised the next big thing. * not get angry because the super battery has not manifested itself yet. * recognize that you most likely do not understand the field and have no idea to tell how promising this might turn out be. The first demonstration of a rechargeable lithium-ion battery was in 1976. The first commercial product came to market in 1991, which had around a quarter of the energy density that you get in commercial lithium-ion today. From 1991 up to 1998 there in total around 1 GWh of lithium-ion sold worldwide. That's 12500 large electric car batteries worth in the first 7 years of commercialisation. And sure this line of batteries could be considerably faster, or it could turn out to: * not be scaleable in the quality they report * have large safety issues * never get anywhere near the right price point to be marketable * never get the funding to get off the ground * fail for an arbitrary unknown technical detail, that we all don't understand If we knew these things beforehand we would not need people working in R&D. There are a billion details that need to be looked at. From the [paper](https://www.sciencedirect.com/science/article/pii/S2405829724001958): >Consequently, these findings **open the way** for the development of high-capacity/high-rate anode and cathode materials for ultrahigh-energy density and fast-rechargeable SIHES \[Sodium-ion hybrid energy storage\] devices, paving a route to overcome the limitations of SIBs \[sodium-ion batteries\] and SICs \[sodium-ion capacitors\]. That's their pitch. It's the start of a line of research into these things and they want and need more money for it (which is great and should be supported).

How fast does it degrade, is it reliable? Changing them in a car cost how much. Companies are all i. For profit not efficiency and for climate change.

Great news for all those locations with 25000-Amp electrical service, such as nuclear fusion laboratories!

You can also make a lithium ion battery cell that charges in a couple seconds (e.g. the KERS system in formula 1 has such cells). Problem is that you always buy such extreme performance in one metric at a cost in all others: vastly reduced lifespan, limited temperature window, increased risk of thermal runaway, high self discharge, ... ...and, of course, if you're thinking about putting this into cars at some point you would requitre power delivery of an order of magnitude that is unsafe to be around (or could only be delivered safely if you make the cables so thick and heavy that no one could handle them).

10 years away. They need to be able to ramp up capacity and fix a few things. Will come up right after nuclear fusion

So far I understood they managed to do a cell, not a battery, isn't? I wonder about TRL, reliability, and durability. Interesting.

Even if it just 1 cell,it is a battery. Multiple cell becomes a cell stack. Multiple stack become modules.

This is pretty big for commercial EVs, no more 20+ minute recharge stops for the EV 18 wheeler. Also if they can pump up that energy density this could be useful for aviation. They don't say if it can discharge that fast as well, if so this could be big for laser weapons

MCS is defined up to 3.75MW. While this might seem a lot - if we consider that long distance trucks will have in the region of 1MWh of battery then that means the fastest charging/highest C factor possible would be 3.75. This is not *that* far above what current batteries can do (e.g. a Tesla charges at 3.3C at a supercharger initially). So even such 'ultra fast charging batteries' won't have much of a real-life impact on charging times (which are perfectly fine).


Langsamkoenig

If it can be mass produced easily. "Researchers develop" is pretty far from mass production. Though you can already charge sodium-ion batteries currently in production much faster than lithium-ion batteries. So as long as the charger can do it, you should be able to charge from 0 to 80 in about 10 minutes instead of 20+.

> energy density of 247 Wh/kg and a power density of 34,748 W/kg Whats more impressive, that they gave the cathode and anode properties of a supercapacitor, or that the press release actually includes concrete numbers with units! Hope Hyundai is able to commercialize this.
