Fully Charged in Just 6 Minutes – Groundbreaking Technique Could Revolutionize EV Charging
Typically, it takes around 10 hours to charge an electric vehicle. Even with fast-charging techniques, you're still looking at a minimum of 30 minutes – and that's if there's an open spot at a charging station.

What a bullshit article. While better anode materials are always nice, these claims about charging speed are just dumb. That's only so much power you can push into a battery and today's 350 KW chargers are probably already the practical limit. And if you can't take a 20 minute break every 400 km or so, you should go home and rethink your life.
Oh look. Another "could revolutionize" article.

All of these speedy innovations are great and everything, but they are impractical for most people. They will be useful for emergency situations and for long trips, but for the large majority of people driving electric vehicles their slow chargers in their houses will work just fine.
I love hearing about new ideas, but it's annoying hearing them phrased like it'll change the entire charging game. It doesn't matter if they invent things that charge cars in 30 minutes. Most people will still be slow charging their car while they sleep.
No revolution is coming. Deal with it. But it's also okay to have up to hour charges. Take a break, get some coffee and everything is fine. If you can sit 3h in traffic to work every day or sleep in front of the store on black friday so you can get 20% off on things you don't need, you can sit every once in a while on long journeys. You need a break from driving anyway.
Eh, 15 minutes of charge every 3 hours of driving is fine for me. Long distance is not a problem with the Tesla network. And it's opening up for everyone else too soon. Hopefully it will cause competition for the other networks and force them to improve.

Abstract
Mixed transition metal oxides are promising anodes to meet high-performance energy storage materials; however, their widespread uses are restrained owing to limited theoretical capacity, restricted synthesis methods and templates, low conductivity, and extreme volume expansion. Here, Mn3-xFexO4 nanosheets with interconnected conductive networks are synthesized via a novel self-hybridization approach of a facile, galvanic replacement-derived, tetraethyl orthosilicate-assisted hydrothermal process. An exceptionally high reversible capacity of 1492.9 mAh g−1 at 0.1 A g−1 is achieved by producing Li-rich phase through combined synergistic effects of amorphous phases with interface modification design for fully utilizing highly spin-polarized surface capacitance. Furthermore, it is demonstrated that large surface area can effectively facilitate Li-ion kinetics, and the formation of interconnected conductive networks improves the electrical conductivity and structural stability by alleviating volume expansion. This leads to a high rate capability of 412.3 mAh g−1 even at an extremely high current density of 10 A g−1 and stable cyclic stability with a capacity up to 921.9 mAh g−1 at 2 A g−1 after 500 cycles. This study can help to overcome theoretically limited electrochemical properties of conventional metal oxide materials, providing a new insight into the rational design with surface alteration to boost Li-ion storage capacity.
Imo the way things stand things are already good enough as they are.
we don't need to double battery capacity/distance or even charging speeds, it's a massive waste of resources that won't benefit the vast majority of people.
from quick google
Every day, there are some 70 Million (M) worldwide driving trips. The average trip duration globally is 15 minutes long. The average trip distance globally is 15 Kilometers / 9.3 miles. The average speed globally is 30 km/h (or) 18.6 mph
so even if you have a 200km worst case scenario range on your EV, unless you are one of those people that are on the road a lot, it literally covers like 99% of your car usage.
Hyundai EVs charge with 350Kw, to 80% in like 15m which is perfectly fine for a longer roadtrip imo. I used to travel 200kms every two weeks and in most cases I took a rest half way through the 2 hour trip anyway to stretch.
if you are one of those guys that will come on and say you drive 500+kms every day and BEV is just unacceptable for you, well guess what, just get a fucking Hydrogen EV, pretty sure those can get up to 1000km ranges already which is more than my Diesel Hyundai.
I asked gpt4 to explain this abstract in terms a high schooler would understand.
Sure, this text is talking about making better batteries. Right now, a type of material called “mixed transition metal oxides” has potential to be a really good component in batteries. But there are problems like they don’t hold as much energy as we’d like, they’re hard to make, and they don’t conduct electricity well.
So, the researchers made a new version of these materials, tweaking them with manganese and iron. They used a new, easier method to make super-thin sheets of this stuff. This new material can hold a lot of energy, way more than the old versions.
The thin sheets also let electric charges move more easily, which is good for battery performance. Plus, they made sure that the material doesn’t expand too much, which helps keep the battery stable over time.
So basically, they made a high-performance battery material that can be charged quickly, holds a lot of energy, and lasts a long time. It’s like creating a new recipe for a better, longer-lasting smartphone battery.
This thread is pure copium.
"Guys, go buy a more expensive car, but instead of taking 6 hours to get somewhere more now take an hour and a half. And if it's a busy travel weekend maybe 3 hours. And don't forget about the trip back."
I'm all for EVs being successful but you all force feeding bullshit hand waving down people's gullets ain't helping.
