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.
