Defects Deliver the Best of Both Worlds: Highly Efficient Ultrahigh Energy Density Capacitor – SciTechDaily
By introducing defects to a common material, Berkeley Lab researchers create a highly efficient capacitor with dramatically increased energy density. Capacitors that rapidly store and release electric energy are key components in modern electronics and power …

To make the new material, the thin film is first deposited via a pulsed-laser deposition process in this chamber. The bright “plume” you see is the laser hitting the target and depositing the material. Credit: Martin/UC Berkeley
