California teen invents device that could charge a cell phone in 20 seconds

[Anto]

Do I hear the major boys knocking on her door now?.

Now here’s the invention that we’ve all been waiting for: A device that instantly charges our cell phones.

A gadget like this might soon be on its way thanks to a bright 18-year-old from Saratoga, Calif., who was recently honored at an international science fair.

Eesha Khare is the mind behind a super-powerful and tiny gizmo that packs more energy into a small space, delivers a charge more quickly, and holds that charge longer than the typical battery. Khare showed off her so-called super-capacitor last week at the Intel International Science and Engineering Fair in Phoenix, Ariz.

In her demonstration, she showed it powering a light-emitting diode, or LED light, but the itty-bitty device could fit inside cell phone batteries, delivering a full charge in 20-30 seconds. It takes several hours for the average cell phone to fully charge.

Khare also pointed out that the super-capacitor “can last for 10,000 charge cycles compared to batteries which are good for only 1,000 cycles.”
Khare’s invention is flexible and could be used in roll-up devices and might even have applications for car batteries.

The judges at the science fare were wowed by Khare’s brilliant invention and the senior at Lindbergh High School in San Jose received the Intel Foundation Young Scientist Award and $50,000.

“With this money I will be able to pay for my college and also work on making scientific advancements,” Khare told a cheering audience after receiving the prize money.

I’m sure her parents are proud and thrilled!

She will be shot soon.

She will be shot soon.

Hmmmmmm

 

[Al Bumin]

Time will tell if this once has legs to stand on.

 

[Baz]

She's definitely gifted and a soon to be prosperous young lady.

Need to hear in Fox news. Get it?.

I can't wait until someone comes up with a pill that can recharge me in 30 seconds!

I don't have cramps and bloating, well ok just a little because you've been hiding my prunes!!

I need my prunes and cold coffee.

Not nearly enough prunes in the Provence to fix that

LOTS OF CHOICES!

GET ME MY PRUNE FIX.... I hear the rumblings..... it's percolating.....

This girl will make a fortune. I can't wait. My POS iphone barely lasts 6 hours on moderate use.

me thinks there might be some R&D needed.

What are the production costs?

How much heat is generated by the unit?

What happens if the unit over charges?

Is it adaptable to current tech?

does the unit prevent over charging of units being charged?

All good questions. I'm not electrical engineer, but I know that my quick charger runs a lot hotter than the regular charger.

one of the problems with the development of super conductors has been heat.

I am wondering if she solved this and if so how.

If this is the case she has something much more valuable than a battery.

 

[Boing]

If this is the case she has something much more valuable than a battery.

Let's hope so.

 

[meist]

She will be shot soon.

It'll probably get buried in legal limbo and if that doesn't work, she'll have an 'accident' :grrrrrr:

 

[BEER]

I can hit that too.

Scientists have invented an aluminum battery for smartphones that can be charged in one minute





LONDON — U.S. scientists said they have invented a cheap, long-lasting and flexible battery made of aluminum for use in smartphones that can be charged in as little as one minute.

The researchers, who detailed their discovery in the journal Nature, said the new aluminum-ion battery has the potential to replace lithium-ion batteries, used in millions of laptops and mobile phones.
Besides recharging much faster, the new aluminum battery is safer than existing lithium-ion batteries, which occasionally burst into flames, they added.

Researchers have long tried but failed to develop a battery made of aluminum, a lightweight and relatively inexpensive metal that has high charging capacity.
A team lead by chemistry professor Hongjie Dai at Stanford University in California made a breakthrough by accidentally discovering that graphite made a good partner to aluminum, Stanford said in a statement.

In a prototype, aluminum was used to make the negatively-charged anode while graphite provided material for the positively charged cathode.
A prototype aluminum battery recharged in one minute, the scientists said.
“Lithium-ion batteries can be a fire hazard,” said Dai. “Our new battery won’t catch fire, even if you drill through it.”

The new battery is also very durable and flexible, the scientists said.
While lithium-ion batteries last about 1,000 cycles, the new aluminum battery was able to continue after more than 7,500 cycles without loss of capacity. It also can be bent or folded.

Larger aluminum batteries could also be used to store renewable energy on the electrical grid, Dai said.
