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.

​A primary obstacle is resistance heating, which strictly limits current computing technologies. We study the Chiral Induced Spin Selectivity Cooling (CISSCO) effect, that may offer a promising solution for energy-efficient local heat management. When current flows between dissimilar materials, a temperature gradient is created - known as Peltier effect. Alike, magneto cooling occurs by magnetization and demagnetization of magnets. CISSCO has similarity with both effects because of spins being aligned at the source by entering the chiral system: thereby the entropy is reduced, and the environment gets warmer - while in the drain the spins are randomized, generating an opposite result. This effect is remarkably efficient.  The effect does not require magnetic materials, is applicable for any source and drain, and is local, thus supplying efficient point cooling.
