Hybrid "power capacitors" that can store as much energy as lithium batteries, but with much higher charge/discharge rates, a huge range of safe operating temperatures, super-long lifespans and no risk of explosion are already in production, says a small Belgian company that's been testing them and selling them for some time.
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.
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.
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.
