      You joke but I literally pictured a super long battery for a solid bit before it clicked. I was thinking maybe it was coiled and technically really long like a spool of wire

    If it were any other company I would be thrilled. With Samsung, this is going to be internet enabled, you’ll need an app to turn your car on and off, and it’ll probably play ads at high volumes constantly while driving.

            These are cells that are meant to be assembled into larger battery packs by electronics manufacturers, like laptop batteries or e bike batteries.

            The cells are fantastic for flashlights, lasers, and vapes, but Samsung does not sell them to end consumers and wishes other companies would not do that either but fuck Samsung I’m not stupid.

                It wouldn’t be dangerous at all to do that. They can be dangerous because the cells are unprotected, so if you short the ends together with something a lot more conductive than your fingers (eg metal) the cell will very quickly overheat and possibly catch fire, since there’s no protection circuit to detect and cut off current when a short is detected.

        I am 100% certain that Samsung is currently in litigation regarding exactly this kind of thing at this very moment. These companies have massive arms for corporate espionage and the like, and because of patent laws, it’s always worth spending time and money protecting your tech.

          Samsung devices & appliances are notoriously prone to catastrophic failure - as a matter of fact, I actually had a Samsung TV melt itself - which turns out is a common issue (Google “Samsung tv melting corner”).

          Then there’s the Samsung battery fire issues, Samsung refrigerator safety lawsuits, etc.

        it’s still a Li-ion (like most current rechargeables) but the electrolyte - the medium that transfers the ions from the anode to the cathode - (the + and -) inside the battery is made of a solid material instead of the current gen liquid ones. The benefits are less weight/size (as liquids take up more space than solids) and a more stable composition - the liquid electrolyte can’t leak - the way batteries get gunky and corroded if left for a while

          And if I understand correctly, they are safer because there is less chance of parts touching inside. I don’t know the correct t terminology, but one of the big problems with current li-ion batteries is that if they get physically damaged, parts inside can touch, which basically starts a short/chain reaction that turns into a dangerous thermal runaway.

          Also if I remember correctly the guy that invented li-ion invented some kind of solid state battery with glass right before he died. I’m assuming this technology stems from that.

          Please correct me if I’m wrong on any of this. Knowledge is power.

      TL;DR: Depends on what you mean.

      Long version:

      Disclaimer: I’m not an expert by any means, I haven’t vetted the links properly (or at all), they’re mostly there for illustration and if you want to read further. Also, the last time I actually read up on this is quite some years ago, so stuff may have changed in the industry and/or my memory on specifics is foggy. Many of the links lead to Tesla sources since I first looked into this topic back before Musk made it known to the public that he’s an insufferable human being.

      Batteries are usually structurally integrated into the chassis with modern EVs, since that means space (and often small weight) savings, and is easier/faster to do in manufacturing.

      With that knowledge, it is safe to assume that replacing a car’s battery is a difficult or next to impossible task, outside of end-of-life reuse.

      But this is actually where it gets interesting, since EV batteries last many years anyways: What happens when the car’s time has come?

      Well… the batteries can be reused. It’s not a trivial process, there’s several ways to do it, but the best intuitive explanation I’ve found is this: In raw ore, lithium and other metals are present at maybe 0.1 or 1%, per tonne of material. In batteries, it’s maybe 99% of reusable, expensive material. Even if you let it be 90 due to inefficiencies in recovery, or whatever, it’ll still make way more sense financially to work with old batteries – once you have the process figured out and automated machinery to get it done in place.

      All that is assuming total destruction of the existing cells, which, depending on their state, may not even be necessary at all. In fact, it looks like all of that may not be needed for as much as >80% of batteries. Wow!

      And we all know the best way to ensure companies are doing something is if the financial aspect aligns with their goals. It’s in their best self-interest to be able to and actually do this.

      So: Replaceability per car – eh, doesn’t look to great. Replaceability across the industry? Perfect.

      Thankfully solid state batteries save 30-50% weight compared to current ones so batteries can be a bit smaller than they otherwise would be. This one will likely be 150 kWh.

      I mean, the headline does say 20 years soooo…

      Also, Teslas are approaching 10 years old and as far as I know their batteries are still going strong (yes, I know their quality control is otherwise sketchy). The Nissan Leaf batteries are getting pretty sketchy, but they don’t have any battery conditioning - just air-cooled. That’s not doing longevity any favors. All other major EVs have battery management systems and seem to be holding up ok. They’re also generally warranted for 8 years. I don’t think they’d only have a 2-year buffer between warranty and expected life.

    Finally. A true alternative to gasoline vehicles has begun to arrive. I’d never buy a current gen or older pure EV because I’d never want to spend $10,000+ on a battery replacement after its 10 years old or have something with a 250 mile range that takes 45 minutes to charge most of the way up. Give the world a 350 mile (real world usage) battery that can charge in under 15 minutes and lasts 20 years, that’s total replacement territory.

      Battery replacement after ten years is for very old EVs shrub much shorter range. The old model Nissan Leaf is what makes these stories. More recent cars have already outlasted the usage that the old pretty bad ones had by a significant amount. Your criticism is like saying you don’t want a mobile phone because the buttons are so fiddly.

        That’s mighty hard of you to really claim, since EV’s only started to become common about 12 years ago. It wasn’t even until 2017 that the EV market broke 1% of vehicles on the road. Li-NMC batteries will eventually fail. They haven’t been in EV’s long enough to say they’ll likely last 15 years. If they industry was really sure they would, the warranty period on them would be better than 8 years or 100,000 miles to provide 70% total capacity. If I only had barely over 2/3 of my battery capacity left after 100k miles I’d be pretty upset.

          Well the original model Nissan Leaf has been available in the UK since about early 2011, which is more like 13.5 years than 11, and I did a quick search for the 2017 Nissan LEAF on more than 100k miles on autotrader and only one of them had lost any battery capacity at all, and it had over 90%. Another one had 120k miles on the clock and was still at 100% battery capacity. You can mistreat a car and it won’t last as long, yes, but it really is the older model that has the common battery problems. The new ones don’t. And there are brands that have much better battery care than the Leafs, with active cooling etc.

          You see, the reason we know they’re lasting longer is, you know, science and math, where they measure stuff and do the sums, and given that the old type of battery declined a lot in the first 8 years and the new type isn’t declining, then all you’ve got left on your hands at the end is just an awful lot of FUD about battery life peddled by an awful lot of people who don’t actually know.

      Solid state has zero possibility of doing either of those. That is one of the big selling points. The others are that they are 30-50% get, they last longer, and they can charge faster.

      from what i understand, most vehicles use LiFe (i think this was wrong actually, i think most modern EVs use li-ion batts, they really should be using LiFe though.) battery technology, which is almost innert compared to LiPo technology, phones use Li ion batteries which are different from both of those.

      Lithium batt technology sucks.

          please inform me whether those batts said “li-ion” on them, or “LiPo” on them, because those are different.

          Most modern phones, to my knowledge, use li-ion batts.

          LiPo has sort of become a catch all for lithium batts, but it’s not accurate.

              they were probably li-ion batteries then.

              Technically LiPo is a subset of li-ion, but it’s still a subset, so.
