One Israeli start-up has invented a novel battery system for smartphones that enables cutting charging times to minutes or even seconds.
The innovative battery relies on nano-technology to synthesise artificial molecules, allowing the device to store energy more efficiently. The inventors described the battery as a super-dense sponge soaking up power much faster than existing devices.
"These are new materials, they have never been developed before," said Doron Myersdorf, the founder and chief executive of the Tel Aviv-based StoreDot, the company behind the new device.
In the core of the new system are the so-called nanodots, bio-organic nanocrystals only two nanometres in size. Essentially bio-organic peptide molecules, the nanodots modify the battery’s behaviour in a way it can rapidly absorb and efficiently retain energy.
While the prototype is currently far too bulky for a mobile phone, the company believes it will have a slimmer, market-ready version available by 2016 that would provide one day's worth of energy after only 30 seconds of charging.
Myersdorf said a fast-charge phone would cost $100 to $150 more than current models and would ultimately be able to handle 1,500 recharge/discharge cycles providing for a three-year life span.
Eventually, the company would like to develop a car battery that is rechargeable in two or three minutes – a major improvement compared with the existing systems that have to be plugged in for at least half an hour in the case of superchargers or overnight if charged from a regular socket.
The project has been backed by multiple high-profile investors including an Asian smartphone maker and Russian billionaire Roman Abramovich. StoreDot declined to reveal which Asian smartphone maker is involved in the project but a video on the company’s website features a Samsung Galaxy S5 phone.
