Energy Storage

1. Electrical Double Layer Capacitors

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

2. Pseudocapacitors

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

3. Real-time videos showing our supercapacitors can be used to power certain electronics.
