AI Customer ServiceWhile 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.
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 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.
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 find needs optimization but has the potential to help power electric vehicles. A battery ’s best friend is a capacitor. Powering everything from smartphones to electric vehicles, capacitors store energy from a battery in the form of an electrical charge and enable ultrafast charging and discharging.
It’s mainly because Lithium-ion batteries pack a punch that Supercapacitors can’t, in the form of specific energy or energy density (Lithium-ion ~250Wh/kg vs. Supercaps ~20 Watt-hour/kg). Recent advancements in lithium-ion battery technology and supercapacitors have been s...
