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.
[ ] your claims are lies.

- discordance 1y agoFUD. - 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.
- FridayoLeary 1y agojust 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.
- dzhiurgis 1y agoThis 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.
- simondotau 1y agoIt 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.
- dzhiurgis 1y agoYes I remember Toyota was meant to announce solid state batteries in 2020 Olympics lol
- blackoil 1y agoIt is relevant for tech announcement not product launch. You'll be able to buy it in couple of months and test it yourself.
- simondotau 1y agoWhen it comes to new battery tech, I treat “shipping tomorrow” as identical to “our engineers came up with a crazy new idea yesterday”. They have even been some next-gen battery products that actually launched and actually got reviewed by “legitimate“ YouTubers, and later turned out to be not as advertised. As far as I’m concerned, it’s all bullshit until it’s in the hands of independent labs.
- toomuchtodo 1y agoMore 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. https://finance.yahoo.com/news/china-car-sales-hit-2025-122600130.html https://finance.yahoo.com/news/china-car-sales-hit-2025-1226... https://about.bnef.com/insights/clean-transport/global-electric-vehicle-sales-set-for-record-breaking-year-even-as-us-market-slows-sharply-bloombergnef-finds/ https://about.bnef.com/insights/clean-transport/global-elect... https://www.iea.org/reports/global-ev-outlook-2025 https://www.iea.org/reports/global-ev-outlook-2025 https://web.archive.org/web/20250904191345/https://www.ftportfolios.com/Commentary/EconomicResearch/2025/9/4/electric-vehicle-adoption-around-the-globe https://web.archive.org/web/20250904191345/https://www.ftpor...
- dyauspitr 1y agoIt’s a copy pasta from 2017, a lot has changed.
- DennisP 1y agoI guess this part applies: > by this time it ships li-ion advances will match it But the reason it applies is that this new battery is a li-ion advance so it only has to match itself.
