Green energy controlled by spin
Looming concerns of climate change and the prospects of sustainable energy resources, such as solar and wind, have entered the global spotlight, triggering the hunt for reliable, low-cost electrochemical energy storage. This ever-growing demands for electrical energy storage have stimulated the pursuit of alternative advanced batteries.
The control over spin statistics in the oxidation process of the active material reduced the over potential. We have shown that utilizing the chiral induced spin selectivity (CISS) effect, we were able to reduce the work function and the internal resistance batteries improving the batteries efficiency and charging rates. This is true also for other source of clean energy such as hydrogen generation.
