Prototype nanodot smartphone battery which charges in 30 seconds
An Israeli start-up company, StoreDot,
recently showed off a smartphone battery which charges in 30 seconds. The
battery is a prototype with nanodot-based technology and as you might expect,
the company have high plans for mass producing it. It has been said that the
technology could change the way that people interact with their phones and
other portable electronic equipment.

Charging smartphones and other
electronics can take a long time and this is down to the fact that the chemical
reactions that take place to provide energy has to be reversed and cannot be
rushed.
StoreDot could be about to change
all this with the radically new design that they have made advancements with,
which could mean charging times could be as little as a few seconds.
The
company are behind nanodots, these are bio-organic peptide molecules, which
have been chemically synthesized. Due to them being small in size they have
electrode capacitance along with electrolyte performance that has been improved
upon. This means that it could take a battery just seconds to fully recharge as
opposed to several hours.

The CEO of StoreDot, Doron
Myersdorf, said ‘In essence, we have developed a new generation of
electrodes with new materials – we call it MFE – Multi Function Electrode.”
He went on to say “On one side it acts like a supercapacitor (with very fast
charging), and on the other is like a lithium electrode (with slow discharge).
The electrolyte is modified with our nanodots in order to make the
multifunction electrode more effective.”
There are other quantum-dot and
nanodot technologies out there but the CEO said that these are heavily based on
metal and this makes the tech toxic. The technology the company makes nanodots
with is comprised of a huge range of raw bio-organic materials which are
friendly to the environment. These raw materials are said to be abundant and to
self-assembling thanks to having a basic biological mechanism. This means that
they are cheap enough for the company to make them.

The batteries self-discharge in a
way that is like that of the lithium-ion cells. StarDot are aiming for a
battery capacity of about 2,000mAh, which is around that of the average battery
found in a smartphone, for their first prototype.
The CEO went on to say that the tech
could also be changed for use in electric cars. The electrodes could be altered
allowing it to have higher currents, along with the use of many cells together.

StarDot is applying for patents for
the new battery design and they are planning on starting mass production of
them for use in smartphones at some point in the latter half of 2016.
