To replace batteries. Scientists have invented supercapacitors — new energy storage devices

The new design of energy storage will allow ions to pass through the “pores” not one at a time, but thousands at once.

Scientists from the University of Colorado in Boulder (USA) have proposed using a new model of supercapacitors so that batteries can be charged at very high speeds. About this writes Popular mechanics.

Inside the batteries, ions are transferred from one side to the other, depleting the charge, and then reverse direction to recharge. As the ions push through the special material, it picks up electrons, which become an electric current flowing out of the terminal. Over time, the supply of electrons is depleted, and the battery discharges. In a rechargeable battery, the ions can return to their original state, and the electrons will then be withdrawn in a new cycle.

Supercapacitor — a new concept combining battery design and capacitor physics. A capacitor consists of two layers of conductive material, between which there is an insulator (for example, glass). This insulator causes energy to accumulate on both sides. In a supercapacitor design, energy is stored on the surface in an electric field that holds the electrons in place. This difference is key: the particles do not attach or detach from atoms and molecules during a chemical reaction, which saves energy and prevents wear and tear over time.

Ankur Gupta of the University of Colorado at Boulder and his team developed an efficient method of charge storage using a porous supercapacitor. Scientists used knowledge of flows passing through pores, — for example, water filtration research — and applied this knowledge to the flow of energy through a porous material.

According to Gupta, supercapacitors are attractive because they can accelerate battery charging and energy release by more efficient movement of ions. This technology has yet to be refined, but researchers are confident that it will prove to be quite viable.
