I’ve been reading about battery breakthroughs for decades. And I remember when the latest in battery tech was alkaline, then Ni-Cd, then Li-Ion, and now LiPo. All of those have ended up in consumer products.
Also, the battery pack for a cell phone 30 years ago was about the same volume and weight of an entire smartphone, with a capacity of about 500 mAh. They are also far cheaper if you account for inflation.
Batteries have improved incapacity by about a factor of 10 and the cost per watt-hour has reduced by about 99% in the last 30 year. All without a single advancement in the technology, apparently.
I wouldn’t call it a single advancement but hundreds. The materials might be largely the same but manufacturing is huge. When you roll up some metal to make a battery then increasing the number of layers is a huge challange when they’re already tiny.
I don’t know in general. I was recently shopping for a UX 250h and I know they only just switched to lithium for the 2025 model with the nx name change.
Toyota switched the camry hybrid from NiMH to lithium for the 2020 model year.
In my head I meant hybrid cars on the road, not necessarily in new production.
LFP is actually a relatively old battery technology, it’s only now that the patent is expired that it’s starting to breakthrough (outside of China, they somehow got a license if I understand it correctly).
QuantumScape is currently building the mass production line for a solid state battery and has been sending prototypes out to their auto manufacturer clients for testing.
It takes around a decade to scale up a process. You’d be shocked at how long it takes to discover something, get investment, file patents, acquire licenses, construct facilities, manufacture the product, and sell to customers. And that’s what it takes to get to just the starting line of being in business.
I’ve been reading about various breakthroughs in battery world for past decade or so. So far none ended up in a consumer product.

What do you mean by that?
I would say there have been a great many advancements in technology. I mean, that’s what all these improvements are, right?
It was sarcasm, which seems to be harder to convey in text than any number of battery advancements.
You skipped Ni-MH there, that was major for not having the memory problems of Ni-Cd. We still use those in AA and AAA rechargeable batteries.
Ni-MH production for EVs was effectively shutdown by Texaco and later Chevron through patent acquisitions.

Holy shit. I had no idea.
Chevron is pretty fucking evil for a lot of reasons, but we’ll add this one to the pile, I guess.
totally TIL worthy
Ni-MH
iswas also in a lot of hybrid cars.Are they still making NiMH hybrid packs?
Lithium is far superior
I don’t know in general. I was recently shopping for a UX 250h and I know they only just switched to lithium for the 2025 model with the nx name change.

A little pedantic note, LiPo is still a type of Li-Ion (maybe I got that right)
and the bigger recent breakthrough was LFP (Lithium iron phosphate / LiFePO4)
And probably safe to call Sodium-Ion and solid state the next big phases of development
LFP is actually a relatively old battery technology, it’s only now that the patent is expired that it’s starting to breakthrough (outside of China, they somehow got a license if I understand it correctly).
You can buy sodium ion cells online right now. It’s not the next phase, it’s here.
Hey! Don’t screw up Lemmy’s Debbie Downer vibe!

LifePo4 batteries aren’t Star Trek levels of advancement, but they sure have changed my life and those of a lot of people I know.
But I do get your drift. It seems like everyday there’s some new breakthrough, and all we see of it is unnecessary AI.
QuantumScape is currently building the mass production line for a solid state battery and has been sending prototypes out to their auto manufacturer clients for testing.
This Undecided with Matt Ferrell video has a good breakdown.
Disclosure: I own 100 shares of QS
$5.05 a share. So for a mere $505 I could also own 100.
