1. Electrical Double Layer Capacitors

Hierarchically porous carbon structures
Highly conductive, lightweight and large surface area

Pseudocapacitors

We developed a pseudocapacitor device with an ultrahigh mass loading of 21 mg/cm² and achieved a remarkable energy density of 7.4 Wh/kg at an average power density of 3000 W/kg.
