18-year old wins award for invention that could charge a smartphone in 30 seconds or less
With semiconductor manufacturers pushing, not only the speed of our
mobile devices with every new iteration, but their battery life as well,
many Android users today are finally comfortably enjoying more than a
full day’s usage from our smartphones and tablets. Still, there are a
few YouTube addicts, game-oholics, or other heavy users that are still
able to make short work of just about any sized battery. The problem
with our current lithium ion batteries isn’t just their size (which has
been growing larger to match bigger devices), it’s also how long they
take to charge (especially in a pinch).
Wouldn’t it be nice if you could play Need for Speed until your
battery was completely dead, find a power outlet, then fully charge your
Nexus 5 in
30 seconds flat? Well, that future is looking a little bit more like
reality after Eesha Khare — an 18 year old high-school student from
Saratoga, California — created an energy storage project that won her
the Intel Foundation Young Scientist Award of $50,000 at the Intel
Science and Engineering Fair.
Eesha developed a tiny supercapcitor that is small enough to fit
inside a cellphone battery and charge it fully within 30 seconds. What’s
more is her tiny supercapcitor is capable of lasting 10,000 recharge
cycles (as opposed to 1,000 in standard lithium ion batteries), and can
easily fold, bend, or roll up, while still retaining its “electro
chemical properties.” Besides just smartphones and tablets, this
technology could also be applied to even higher capacity batteries like
those found in automobiles.
It’s clear that with HD streaming, console quality games, and bigger
HD displays, something needs to be done to make our devices more power
efficient. Where we often think throwing more mAh’s at a device is the only
solution, charging them quickly is a factor many of us may have
overlooked. My question for you is, due to the nature of
superconductors, would you accept shorter overall battery life if your
device was able to fully charge in 30 seconds? Or do you find that an
hour to 2+ hours charge time is acceptable if your battery can take you
throughout an entire day?
