    Not once in the entire article do they measure energy in a unit suitable for measuring energy.

    Measuring batteries in km is misleading and nonsensical. Batteries do not have a distance range. Cars have a distance range, based on many factors, only one of which is battery capacity.

    Similarly, please stop measuring light output in watts that an imaginary incandescent bulb from 30 years ago might theoretically have used to produce that amount of light.

      Stopped reading after: “increase in battery capacity and charge time was achieved through a “brand-new superconducting electrolyte formula” that results in improved conductivity.”

      I guess the source, author or both don’t really care about technically accurate terminology. If it’s good enough for Star Trek, it’s good enough for us.

      I remember having the light-measured-in-watts discussion years ago when LED lights were still considered a novelty. Of course, this was with a videographer who actually understood the issue. He complained that it wasn’t a good idea to limit car headlights based on their wattage, which is how all the laws at the time were written. 5 years later, suddenly there were LED headlights blinding everyone.

    Show me an article promising substantially better battery tech in less than 5years and I will show you a steaming hot pile of crap.

      We’re past that point. Every claim you heard in the last 10 years has been researched to its end. Some worked out, some didn’t, but we didn’t need all of them. Just one or two breakthroughs are enough.

      These are going into production this year They’re not lab experiments anymore.

        Want to join me on an online betting platform and wager against my statement that you will not be able to purchase what is described here in 2years? We’ve seen these kinds of promises over and over again with battery tech. Slow incremental changes yes. These types of breakthrough reports are consistently garbage regardless of how close to market they claim they are. I presume they put these out to stir up investment.

          I don’t bet, but CATL is a company that already manufactures tons of batteries for EVs. It’s not some fly by night operation hoping to live off venture capital. If it’s not in actual BEVs within 2 years, it’ll be because car manufacturers themselves take longer than that to integrate it into existing designs.

          But is this not the tech that Toyota is bring to market ?, they have a working prototype I believe.

            This isn’t. Toyota is claiming they’ll have a solid state battery production ready in a few years, which is a substantial improvement over even what this article is claiming.

            Toyota’s is being developed largely in house it seems, and while they do have prototypes, they’re not really expecting them to be in consumer vehicles until 2027.

            This article is talking about the same old liquid technology with just an improved chemistry.

          I agree that some of it is marketing, some of it is tech bloggers trying to get clicks, but some of it is also real science that does have an effect. You probably won’t notice when it goes into effect, just that battery technology will slowly get better. It doesn’t really matter how fast this can charge until it’s supported in the infrastructure (and most people will charge at home overnight anyway), so you’ll only hear that charging is slowly getting faster over time, not sudden leaps. It doesn’t mean it’s all smoke and mirrors though.

      But in my lifetime battery tech has improved tremendously. Even in the last 5 years charge density and speed of recharge has had massive improvements.

          always. but saying “oh there’s all these developments and they’re all vapor” - i get sick of armchair experts telling everyone they know better every time on-the-horizon announcements come out. I get not all of them ever get produced, but by current phone has 10 times the battery capacity of my first one, and the quick charge really does give me something like an 80% charge in 15 minutes or so.

          some of these claims are pretty out there but development keeps going and by the time something with high levels of performance is in your car these guys will be smugly crapping on something else to assert nerd authority. i guess it’s just a social niche thing and nothing about batteries 🤷‍♂️

    Know what’s better than a battery that charges fast? A train with a catenary that never has to charge at all

      It’s not remotely realistic to expect a sudden drastic change in infrastructure like that. While we should work toward such goals, statements like this are ignorant of the time and efforts necessary to affect such change.

        Kinda telling on yourself by calling it “drastic”. What exactly is “severe” or “rapid” about supporting alternative methods of transportation?

      Damn, you really incensed a whole bunch of people who seem to like living in soulless, identical car-centric hells. What normal person thinks you expect “a sudden drastic change” from a silly comment like this?
