• 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. 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.
