It opens the door to a new era of electric efficiency. Researchers believe they’ve discovered a new material structure that can improve the energy storage of capacitors. The structure allows for storage while improving the efficiency of ultrafast charging and discharging.
The new structure sits in a physical and chemical balance between conductivity and non-conductivity, letting it more effectively retain energy. By accident, the researchers found that a tiny gap in the core increases the relaxation time — a term used to describe the period over which the capacitor loses charge.
However, their Achilles’ heel has always been their limited energy storage efficiency. Now, Washington University in St. Louis researchers have unveiled a groundbreaking capacitor design that looks like it could overcome those energy storage challenges.
The two materials, the researchers found, can be combined with water to make a supercapacitor — an alternative to batteries — that could provide storage of electrical energy.
Sayeef Salahuddin Capacitors are one of the basic components of electrical circuits but they can also be used to store energy. Unlike batteries, which store energy through electrochemical reactions, capacitors store energy in an electric field established between two metallic plates separated by a dielectric material.
While batteries excel in storage capacity, they fall short in speed, unable to charge or discharge rapidly. Capacitors fill this gap, delivering the quick energy bursts that power-intensive devices demand. Some smartphones, for example, contain up to 500 capacitors, and laptops around 800. Just don’t ask the capacitor to store its energy too long.
