Israeli startup StoreDot recently demonstrated the prototype of a nanodot-based smartphone battery it claims can fully charge in just under 30 seconds. With the company having plans for mass production, this technology could change the way we interact with portable electronics, and perhaps even help realize the dream of a fast-charging electric car.
‘In essence, we have developed a new generation of electrodes with new materials – we call it MFE – Multi Function Electrode,” StoreDot CEO Doron Myersdorf said. “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.”
The company says that unlike other nanodot and quantum-dot technologies that are heavy metal based, making them toxic, its nanodots are made from a vast range of bio-organic raw materials that are environmentally-friendly. These materials are also naturally abundant, and the nanodots employ a basic biological mechanism of self-assembly, making them cheap to manufacture.
Self-discharge characteristics are similar to those of lithium-ion cells and, for its first prototype, the company targeted the approximate capacity of a smartphone battery (around 2,000 mAh).
