The next-generation of lithium-ion batteries is really going to ensure that users get all-day, and even more battery life out of their devices. A team of researchers in Singapore have developed this improved lithium-ion battery tech, which is capable of recharging a battery to 70% in just two minutes, yes: 120 seconds.
The clinch, is that this isn't a new battery technology, but it improves on the existing technology that is used. The improvements are coming from a form of nanostructures, where instead of traditional graphite used to create the lithium-ion battery's anode, this new technology uses a cheap titanium dioxide gel, which is a similar material to that used in sunscreen, that absorbs UV rays.
The scientists have discovered a way to turn these compounds into nanostructures that super-speed the charging process, with this change making lithium-ion batteries capable of charging 20x faster, and lasting up to 20x longer. Associate Professor Chen Xiaodong of Nanyang Technological University said in a release "With our nanotechnology, electric cars would be able to increase their range dramatically with just five minutes of charging, which is on par with the time needed to pump petrol for current cars". The researchers hope to have this technology on the market within two years, which should be perfect timing for our next, next-gen smartphones and electric cars.
“charges 20x faster, lasts 20x longer”
But not at the same time...?
Probably not that costly, but people would pay a fair premium for a cellphone battery that only needs to be charged every three or four days.
That itself would allow a battery to last longer.
I’m old school, I started building hot rods in 1945, have held one record and and helping a friend get his car ready to set a new record for gasoline of over 400 mph, he has already gone 368 mph on gas.
That was the silver pill, wasn't it? I read about in a Tom Swift book.
Oops, never mind
I accidentally stumbled onto the Luddite thread
Lasts twenty times as long probably means that it will hold a charge twenty times longer while not being used.
You really need to get excited about something else. Ha Ha! Maybe a regime change in the next two elections. Now that would be exciting! Oh boy, in trouble now. And it is coming........
Murphy's Law?
CA....
Well, now, let’s do a little simple math.
Let’s say we have a 2000 mAh battery that will accept a charge current of 500 mA, and it takes 5 hours to fully charge (there are always substantial losses in the charging process.) If said battery can be charged 20x faster (ie., in 15 minutes), our charge current is up to 10 amps. That’s a MUCH bigger, more expensive charger.
Similarly, if the battery has 20x the capacity (40 Ah), given the original 5 hour charge time, again, charge current is 10 amps.
If the battery has 20x the capacity and can be fully charged in 15 minutes, then charge current is 200 amps.
Obviously, the battery banks needed to propel vehicles are MUCH larger. The recharging stations could be quite, uh, interesting. Plus, heat dissipation in both the charger and the batteries being charged would seem to be a very large concern.
It would be fantastic, but I’ll remain a sceptic until we see these things hitting the streets.
A battery which has 10x the capacity of today’s batteries which could still be charged overnight, let alone in a few minutes, would have a significant impact.
I’m quite happy to move off of dino fuel and if there is a break through that legitimately enables that transition - great! But I remain a sceptic until I see the proof.
“What the hell has been invented in Singapore ?”
Lots of stuff. There’s the Singapore Sling, and Singapore cookies, and that’s just off the top of my head.
Maybe have a large flywheel driving a shaft to the rear wheels rather than having mottoes om the wheels.
Didn't Audi win a big race with electric vehicles?
lol
This would also be a huge boon for Solar power.
They shall be internal combustion engines of the reciprocating type!!!
No problem. Memory is cheap these days...
They suppressed the 200 mpg carburetor too. Bastards.
