Engineering a battery fast enough to make recharging like refueling

INTRO: Right now, electric vehicles are limited by the range that their batteries allow. That's because recharging the vehicles, even under ideal situations, can't be done as quickly as refueling an internal combustion vehicle. So far, most of the effort on extending the range has been focused on increasing a battery's capacity. But it could be just as effective to create a battery that can charge much more quickly, making a recharge as fast and simple as filling your tank.

There is no shortage of ideas about how this might be arranged, but a paper published earlier this week in Science suggests an unusual way that it might be accomplished: using a material called black phosphorus, which forms atom-thick sheets with lithium-sized channels in it. On its own, black phosphorus isn't a great material for batteries, but a Chinese-US team has figured out how to manipulate it so it works much better. Even if black phosphorus doesn't end up working out as a battery material, the paper provides some insight into the logic and process of developing batteries... (MORE)

Can we run a motor using only magnets? Would magnets last longer and be easier to replace than batteries? I think I saw someone do this once on YouTube but can’t find it. No wires, just a rotor and magnet.

I'm not sure how similar it is to the heralded faster charging lithium batteries that made it into smartphones but there were a number of teething problems. One was the initial processing of carbonised "nanotubes" was expensive, the other was at such a small level (due to it's intricacies) it could lead to structural failure which resulted in some of the faster charging batteries overheating and rare cases exploding.

Elte posted something possibly akin to that in the other place for de-bunking, but these are not without wires. They're certainly not examples of perpetual motion, either (even those who claim to have fiddled with them assert that the magnets expire eventually). At first glance they don't seem possible without trickery, but an electronics hobbyist with plenty of junk lying round could set-up one of the examples and test such first-hand to settle it for their own satisfaction. I mean, it's not expensive rocket equipment or involves traveling thousands of miles, so that everyone has to rely on the dictums of sedentary couch skeptics.

Dozens of other toy examples, different arrangements of the approach or scheme (or faux play on it?)

"It is running purely on the magnet arrangement. However, the generation of electric energy is not continuous because the Neodymium magnets lose their magnetic property due to aging."

Do free energy magnetic motors really work?
https://www.coffeetablescience.com/2014/...eally.html

"But in reality, it is the magnetic energy that is being used to put the motor into motion and over a period of time, the magnets will lose their magnetism and the motor will stop. But again, all one needs to do is replace the magnets and the motor will be workable once again. There is some work that has been put into the type of magnets that can be used for such motors and Neodymium magnets have been claimed to offer the best results."

Of course, getting published means little these days what with peer review being a joke even when it exists, the predatory journals, careers and funding revolving around "publish or perish" desperation, research integrity compromised, business and political ideology influence, replication crisis, etc. Thus:

Couple of skeptic discussions about this or that toy in the forums below. Glancing over, doesn't appear anyone actually tried to replicate, so just lounge-chair lecturing about scams.
