Every day it feels like we’re getting closer to battery revolution.

It’s been “every day” for as long as I can remember. Some new world-changing battery tech is right around the corner, but never manages to appear in consumer vehicles…

Battery tech has still come a long way since say 10 years ago, even though the “next gen” stuff hasn’t made it to scaled production. Looks like this is the beginning of scaled production, though.

Production is a tiny link in the supply chain.

According to the article they’ve sent them to manufacturers for testing and that’s it.

Even if they were able to make them they’d still be impossibly expensive for decades, as the implications of such a technology would be gargantuan.

Nah, see the battery density graph here. Batteries have made great progress already, and it’s accelerating because suddenly there are trillions of dollars on the line for anyone that can make big strides in battery technology.

Battery tech is constantly having huge breakthroughs. They are just come in small steps.

I mean a smart phone is literally a battery powered computer. It’s absolutely astounding compared to what we had 10/20 years ago.

Only thing I’m upset with is that we get more battery capacity, but not longer battery time. I want to clock my phone down to save power, but that’s not allowed.

Most phones have some sort of “Ultra power saving” mode that gives a lot of battery life.

It’s absolutely allowed.

It’s not as good as previous versions but I am running stock android and I have wifi power saving and phone (background) power saving modes available. I just checked and the estimate of time until zero percent battery goes from 22 hours to 28 hours with the node that limits backup processes, and that is with 59% on the battery.

There was a power save mode on my old phone that made everything grey screen and stuff that was way better. I think I enabled it for a camping trip once and used like 20% battery in 3 days.

Yeah the more power phones have available the more manufacturers use.

It’s why I miss replaceable batteries.

My guy, those are opposite things…

Not really. They have massive breakthroughs that increase capacity and charging hugely.

People just seem to expect some world changing development constantly.

Depends on how you define “constant”. Battery prices have been falling year over year, no thanks to technological improvements.

If we’re referring explicitly to Academia and R&D, then OP is correct. You’re main point is that these huge breakthroughs haven’t affected the market, but OP isn’t arguing that.

You’re both talking past each other.

The difference is this is actually shipping to manufacturers.

Solid state batteries are already being produced at scale. It’s happening.

There may not be a revolutionary discovery, but we are nearing a tipping point where battery makes more sense for most disconnected power storage than anything else.

The cell phone I had 30 years ago had a battery pack that was about as big as my current cell phone and was 500 mAh. My current cell phone has a little battery tucked away in it that stores 4000 mAh, recharges about as fast, and can be recharged more before it loses a significant amount of its capacity. It also costs about 1% per mAh of the price of that battery from 30 years ago.

Just because you haven’t bothered to investigate advances in battery technology doesn’t mean significant advances haven’t occurred.

…what else are you using for “disconnected power storage” than batteries?

The cell phone I had 30 years ago had a battery pack that was about as big as my current cell phone and was 500 mAh.

Please tell me what part of my comment led you to believe I was insinuating battery technology had not improved in the last 30 years…

Please read better.

Fossil fuels are currently the largest disconnected power storage by overall power used. You know, the thing cars use when they aren’t EVs. You may have heard of diesel and gasoline generators, or oil-fueled ships.

As per the previous part of my comment that you quoted, my point was that incremental changes can accumulate to the point where at some point revolutionary changes can occur. We increased capacity and longevity by a factor of 10 over 30 years, have a new technology hitting mainstream, and another that could double power density in the next 5 to 10. Yet you seem skeptical that’s possible, in spite of the decades of advances we already have made.

True, as far as big leaps go there hasn’t mean anything since the introduction of lithium based batteries to the market.

Until now. This is it and they have production working. Safer than lithium. Longer lasting, quicker charging, should perform fine in extreme cold, more energy dense, and solid state.

The next big thing is finally here.

I know you’re correct, since there are now solid state batteries on the market which outperform liquid-electrolyte LiPo batteries, but just stating “we’re at the tipping point” without dropping any link as evidence makes your claim very unconvincing.

That guy on Undecided is a bit of a dunce. He never actually checked or tested in any way that the yoshino psu uses real solid state batteries. He just bought it from Amazon and it’s advertised on Amazon as having them.

But they likely aren’t solid state batteries in that psu he bought. He even admitted as much in a podcast just last week.

Other people have done teardowns on those yoshino batteries and have apparently found that they are not solid state. They still contain a liquid.

Here. I think he talks about it somewhere around 25 minutes in. https://www.youtube.com/watch?v=aciA1dKz5iE

I hope you’re right, but I’ll believe it when I see it.

A giant name like samsung and the auto makers they’ve teamed up with like Toyota aren’t going to bullshit about the batteries being in production. There’s no benefit to doing so. It’s not like they’re trying to raise investment capital.
