Berkeley Lab scientists create microcapacitors with ultrahigh energy and power density. The microcapacitors are made with engineered thin films of hafnium oxide and zirconium oxide. The technology ...

Scientists from Lawrence Berkeley National Laboratory and University of California Berkeley developed microcapacitors with ultrahigh energy and power density that could be used for on-chip energy ...

(Nanowerk News) In the ongoing quest to make electronic devices ever smaller and more energy efficient, researchers want to bring energy storage directly onto microchips, reducing the losses incurred ...

Pseudocapacitors are a type of electrochemical energy storage device that combines the high energy density of batteries with the fast charge/discharge rates and long cycle life of capacitors. They ...
