I didn't see anything in the article about battery capacity or the density. This (with the other info in the article) would tell us if this is groundbreaking or not.

> When the battery is at a 20% state of charge (SOC), the Shenxing battery will deliver up to 830 kW
Crazy times we live in when 1000hp+ cars are nothing special anymore.

Without knowing the energy density what is the point here?
dzhiurgis · 3h ago
The headline is 12C charge rate, not capacity. Also charging below freezing temperatures is huge achievement for LFP.

Hmm batteries don't have range, vehicles have range. Battery have energy storage capacity and I don't see it listed anywhere very annoying.
I bet a could get 470 miles out of 75kwh battery under the right conditions with the right vehicle. A Chevy Silverado EV got 1000 miles out of a 200kwh and its a brick.
Saying a battery has range is a nonsensical statement. Tell me how much energy it stores and how much it weighs thats whats important.

Gravimetric energy capacity limits range, which is why ICE cars outcompeted electric cars for a century until the batteries got Goodenough.
Basically the problem is that, once most of the vehicle's weight
is battery, adding 5× the battery capacity adds 5× the weight and thus 5× the rolling resistance, so it only increases the range slightly.
LFP has historically been inferior to other lithium-ion chemistries like NMC in gravimetric energy density, so the range of the resulting vehicle is a major consideration.
That's why vehicles like Semi trucks can get by with batteries that are only ~4x bigger than a Silverado EV, weigh 8.5x more, and still manage to also produce higher ranges.

TFA says it’s 470 miles of range under the WLTP which seems to be a fairly standardized test procedure for light vehicle fuel economy and emissions.
One could in good faith assume it means “install this in a normal light vehicle (sedan?) and you’re likely to get about 470 miles of range when driven under normal conditions”.
That said I agree that range is NOT the best way to measure a battery’s energy storage capacity - definitely not the right unit, it’s like measuring computing capacity in megahertz. Oh wait :)

It's just LiFePO4 though (which laptop batteries have been using for many years now), still not solid-state. Still a liquid electrolyte susceptible to dendrite formation, thermal runaway/self-ignition, ejecting flammable gases and hot sparks, still capable of contributing to explosions.

I think you're confusing li-poly and lithium ion, with lifepo4. There's no shortage of videos on youtube of people cutting open lifepo4 with kitchen knives, band saws, and hammers without ill effect.
igor47 · 5h ago
Lifepo4 is much much less likely to runway self ignite than li ion batteries, at the cost of lower energy density. I'm surprised to hear of laptops with lifepo4 -- what are some examples?
bahmboo · 5h ago
You are incorrect. Laptop batteries are overwhelmingly NMC or similar chemistries. I don't know of any LiFePo4 laptops. Also LiFePo4 is extremely safe. So like another poster suggests I think you've got your chemistries mixed up.
Dear battery technology claimant, Thank you for your submission of
proposed new revolutionary battery
technology.
Your new technology
claims to be superior to existing
lithium-ion technology is is just
around the corner from taking over the world. Unfortunately your
technology will likely fail, because:
[ ] it is impractical to manufacture at
scale.
[ ] it will be too expensive for users.
[ ] it suffers from too few recharge
cycles.
[ ] it is incapable of delivering current
at sufficient levels.
[ ] it lacks thermal stability at low or
high temperatures.
[ ] it lacks the energy density to make
it sufficiently portable.
[ ] it has too short of a lifetime.
[ ] its charge rate is too slow.
[ ] its materials are too toxic.
[ ] it is too likely to catch fire or
explode.
[ ] it is too minimal of a step forward
for anybody to care.
[ ] this was already done 20 years ago
and didn't work then.
[ ] by this time it ships li-ion advances
will match it.
- CATL currently manufactures around 40% of the worlds EV batteries. They know how to scale manufacturing.
- LFP batteries do not catch fire or explode.
- Most of your other comments don't apply either.

just a copypasta i particularly like. It's a checklist i don't know which ones apply here, but it's likely that at least one does.

More than half of vehicles sold in China currently are battery electric or plug in hybrids. Similar for 25% of global vehicle sales as of this year. Batteries have already won, it’s just how fast they scale up that’s up for discussion.
This joke was funny a decade ago. EVs have been practical for ages now. See how well early model Teslas fared. Some people doing 1-2 million miles. 300k miles is not uncommon.
You don't need revolutionary batteries (similarly you don't need next generation nuclear plants, ordinary ones create so immense amount of wealth for generations). Batteries improved like 10-15% since early Teslas. Similarly motor/aero/electronics efficiency. Overall 30% gain in range. If right charge infrastructure it's perfectly enough for 99% of passenger cars.

It was funny a decade ago, now it’s no longer funny… but it’s still completely relevant. Battery bullshit is still as prevalent as ever.
Toyota, for example, is seemingly trying to outdo Musk’s “self driving next year” claims with their own “solid state batteries next year” claims. Toyota have been making these promises for nearly a decade now, and it looks like Musk’s lies will come true before Toyota ever ships a single solid state battery to a customer.

It is relevant for tech announcement not product launch. You'll be able to buy it in couple of months and test it yourself.

Yes I remember Toyota was meant to announce solid state batteries in 2020 Olympics lol

One funny thing though... the issues have had more to do with volumetric energy capacity than weight. See also tests like this: https://www.youtube.com/watch?v=UmKf8smvGsA
