Battery
life remains the number one annoyance for smartphone owners, but it
feels like manufacturers have hit a wall figuring out ways to improve
it. But hey, if we can’t have more power in something the same size,
then maybe being able to charge it up faster is the next best thing?
That’s what StoreDot is betting on with its proprietary battery
technology and chargers, which can completely refuel your phone from
empty to 100 percent in around five minutes.

We
got a live demonstration of the technology at the Mobile World Congress
trade show in Barcelona, and it works. They showed us a Samsung Galaxy
S6 with a modified battery and charging port being charged up from
around 10 percent to 100 percent, and it took 5 minutes and 25 seconds.
We also spoke to CEO and founder, Doron Myersdorf, about what makes
StoreDot’s solution unique.
“The
physics and the chemistry of what’s happening inside the battery is
new,” Myersdorf told Digital Trends. “It’s a new generation of lithium
ion batteries.”
There
are a lot of new fast-charging standards and claims in the industry
right now, but Myersdorf believes many of them are achieving faster
charging speeds at the cost of lifespan. A traditional lithium ion
battery can survive around 600 cycles of charge and discharge before
it starts to deteriorate. Myersdorf argues that by doubling the current
to achieve faster charging they are effectively shortening the battery’s
useful life.
Anyone
familiar with fast-charging right now will know that the phone can get
awfully warm. We worried that this might be a factor with StoreDot’s
tech, but during our tests the temperature only rose 4 degrees celsius
during the charging process. We handled the charger and phone
immediately afterwards and neither one was hot. This is partly because
the process is so quick.
Apparently,
the problem isn’t usually the battery, because there are low resistance
materials inside. The real challenge is in the charger and connection.
This means you can’t have a wire between the phone and the charger. It
needs a solid connection.
StoreDot
used a wall-mounted charger unit that was quite large, but they also
showed another, smaller, wired charger that can do the same job. The
thing that immediately jumps out is the requirement for a large contact
area between the phone and the charger. They used a 20-pin connector for
the demo, because there’s no connection type right now that can deliver
the wattage required.
“Even
USB Type-C would need to be modified in order to enable five minute
charging,” said Myersdorf. “This is a whole ecosystem effort that needs
to happen.”

That
means that there’s an insane amount of coordination needed for this
battery improvement to happen: StoreDot’s batteries have to be in the
device; There has to be a suitable connection port to enable the top
speed charging; And you need one of StoreDot’s 150 watt chargers.
The
batteries are similar to what we use today in terms of size and
performance, but the need for a new charging port will obviously pose a
challenge.
The
new technology is also more expensive right now, perhaps double the
price, but that will come down with scale if it is adopted by a major
player and there’s every indication that it will be. It’s no secret that
Samsung has invested in StoreDot and there are other interested
parties.
“We
are working in parallel with the larger OEMs [Original Equipment
Manufacturer] for smartphones,” explained Myersdorf. “Six out of
the 10 major smartphones OEMs are in line for testing and we’re also
talking to the large ODMs [Original Design Manufacturer], those that
make the batteries, because we will need to provide high volume very
quickly.”
The
ability to charge a smartphone fully and safely in five minutes would
be a great differentiator for any new flagship. Myersdorf believes 2017
will be the year for a mass production launch, so we could see this in
the Samsung Galaxy S8 or the LG G6 at next year’s MWC.
The technology also has potential applications beyond the smartphone.
“If
this chemistry works as we show, there’s no reason we couldn’t charge a
car in five minutes,” says Myersdorf. “We would just need a more
powerful charging station.”
That
could solve a real headache for the electric car industry, allowing
electric car drivers to juice up in the same time it takes to fill a
tank of gas.
Thank you.
