    Every day it feels like we’re getting closer to battery revolution. It really makes you wonder how different the world will be once we have these incredible batteries actually working at consumer level.

      They’re coming off a pilot production line and have shipped to vehicle manufacturers to see if they want to incorporate these into upcoming models.

      Problem will be the price for the first run of this tech. They’re targeting “ultra premium” vehicles until they can scale and optimize manufacturing.

        The market will segment away from the current tech anyway. CATL Sodium-ion with comparatively low densities but also extremely low prices per kWh will likely win the low-end market and the market for stationary solutions. This is just due to the much lower resource costs. The high-end will be up for things like this battery by Samsung (or other comparable pilot products). The current technology will likely be in a weird middle spot.

          And those cheaper batteries may not be as compromising as people think. In terms of kwh/kg, the sodium-ion batteries coming on the market now are about where lithium poly batteries were about 4 years ago. It takes a few years before new batteries make their way into EVs, which means EVs being purchased right now have batteries with a similar kwh/kg of the new sodium-ion batteries. Those batteries are around 30% cheaper and don’t have the same level of fire hazards as some lithium chemistries.

          So if EVs on the market today have adequate range for your use, you’ll probably be just fine with a future sodium-ion EV.

          It will still be a dramatic improvement because these packs will be able to hold the max charge that the charger can support for much longer. E.g., a car that can hold 350kW from 0-90 is much better than one that peaks at 350kW for 2 seconds before dropping to 150 or 100kW for 40-90%.

      Can you imagine not having the constant traffic noise played into your ears like tinnitus, being able to maybe actually breathe the oxygen nature provides. That’s probably gonna be what it will be like. But still, ev are just a stop gap, more privately owned cars isn’t the solution in my humble opinion, it is a start towards it.

        Totally with you, but tire dust is one of the major pollution particles from cars, maybe even the worst AFAIK. That, sadly will not go away but it is still leagues more desireable to have everything on electric than fossil fuel. Can’t have perfect stop good enough.

          Yep, tire pollution is even worse with EVs due to their weight. But overall it’s still much better as you said.

                That’s the real kicker. Gets especially hard if you don’t want a Tesla.

                Many of the conservatives who cite heaviness of EVs as a problem didn’t say shit as ICE cars got heavier and they bought F150s to go to Walmart.

                There’s no reason to think that will last. The kwh/kg of batteries improves by 5-8% per year, and we’ve been in the higher end of that range the last few years. Meanwhile, EVs are about 30% heavier. It will take a few years of improvement to make up that gap, but there’s every reason to expect this trend to continue.

                Also, it takes a few years for new batteries to find their way into existing models. 1.08^4 = 1.36, which means improvements in batteries since 2020 could have made up this gap already.

                  Yes, sure, batteries are evolving and there are solid state batteries on horizon, though probably very expensive initially. There is also a concept of getting energy wirelessly from road, which could further reduce battery sizes. I’m sure the future is bright.

        The tire noise EVs make is about the same as an ICE car at about 50 kph (30 mph) so it doesn’t make much difference on busy roads. It does make a huge difference in slow traffic.

        The traffic noise will stay the same, from tires, honking and some fake engine noise they’ll mandate for pedestrian safety.
        Do yourself a favor and spend some time in an area without cars. It’s amazing what it does to your mental health.

        About noise, above 30km/h electric cars are as noisy as gas powered one.

        It’s better but not the panacea either.

          Solution: 30km/h speed limit in cities, which is a good idea anyway for safety reasons.

            Yes, it’s better for safety and health reason.

            Plus 30km/h is in the speed range of bikes, so it become much more accessible to bike around in the city and more people start to do it.

      I waited 4 years for battery technology to get better before bring an EV last year. The “battery revolution”, with all the news being generated weekly for years, is still not here. I don’t give a fuck about theoretical battery range - give me the actual battery in a car, THEN it’s newsworthy. Now it’s all just theoretical, which we consumers can do fuck all about.

        And that’s the thing. As much as we’ve gotten used to it over the past hundred years, progress is absolutely not automatic.

        If people don’t buy the current stuff, it reduces the chance of advancement for that tech. Most things will only get better if people are buying the current versions.

        We’ve had solar power tech for 50 years. Solar initiatives under Carter were actually pretty good. You know who killed it, or I expect we’d have solar on most roofs today.

        I recently visited Switzerland, and the amount of rooftop solar there was insane.

        (Solar is of course closely linked to battery tech.)

          I totally agree with your statement, but in the 4 years I waited, nothing has actually happened with the batteries on EVs (except for a bit faster charging on already insane charging times).

        Well, Toyota has promised 2026 for their battery tech and hasn’t changed that guidance, so I think there’s a decent chance they’ll stick to that timeline. I don’t know if Samsung is their supplier or if they’re competing on the tech, but if it’s the latter, I expect we’ll see something in the next 2-3 years.

          I’m still convinced Toyota is just announcing breakthroughs miracles in battery tech Coming Soon™ because they shit the bed so hard on the first round of EVs. Now they’re trying to discourage people from buying EVs now while they play catch-up.

            Well, the good news is, nobody is making an actual solid state battery car, so if they don’t deliver, I’m not out anything. The current set of EVs aren’t good enough to replace our family car (we like road trips, and even 300 miles range is too little), so I’m waiting regardless. I’ll be looking for announcements in the next year or two.

            Both of our cars are Toyotas though, because they make really good cars. We have a Sienna for our family car and a Prius for my commuter, and I’m probably going to replace that Prius with an EV if I can find a good deal on something with 150 miles range. The Sienna is getting old (nearly 200k miles), but it’s reliable, so I’m holding off until I can either get a good deal on a hybrid/ICE, or reasonable EVs are released. If that’s Toyota, great, but I’m not buying the first gen of anything regardless.

              I’ve found the current gen of EVs is perfect for road tripping with my family. The battery range is perfectly sized for the bladder sizes of my kids. It works really well if you’re road tripping at a casual pace. However I know a lot of people that like to “death march” road trip where they won’t stop for 500 miles at a time - so I admit it’s definitely not for everyone.

                Yeah, I have kids, and we can usually get about 300 miles before someone needs a bathroom break. So usually I refill gas (<5 min) while the kids go to the bathroom, and we usually pack enough food with us (sandwiches and whatnot) that we only need to go to a restaurant once on the trip.

                An EV could work if fast chargers were as plentiful as gas stations, but in many of the areas we go (I live in Utah and travel to WA, MT, ID, and CA frequently), they’re pretty infrequent. So we’d need to plan stops based on charger availability, not on bladder size, which means an extra recharge or two for the trip. It’s getting better, but every time I look at maps, there are maybe one or two chargers in a 50 mile radius, so if it’s full or out of service, we’d be screwed.

                Now, if gas stations started offering EV charging, I’d probably be looking at them today. Gas stations are perfect because they often have fast food, bathrooms, and snacks, all of which are essential for road trips.

                As another anecdote, my coworker just bought a Model 3, and he frequently says he can’t reasonably visit places within our state because the charging network sucks. That’s a pretty serious concern for us, since we like camping, which means pretty remote trips.

      One important thing to remember is the that battery capacity is unlikely to improve anymore, we should mostly improve charging, lifespan, safety, etc.

      I doubt that we will ever see batteries that have much more capacity per weight than what we have now.
