Hybrid supercapacitor with high energy density
Asymmetric supercapacitor device with high energy density and high power
The transition to renewable energy and electrification is increasing demand for energy storage systems that combine high power with high energy density. Lithium-ion batteries offer high energy density, but charge and discharge slowly and depend on critical raw materials. Conventional supercapacitors charge and discharge rapidly at high power, but their low energy density and high fabrication cost limit their use in energy-intensive applications.
We have developed a new asymmetric supercapacitor with increased energy density while preserves high power and long cycle life. The electrodes combine porous carbon matrices with metal oxides, thus having high surface-to-volume ratios and redox reactions (hybrid electrodes). The final step of electrodes fabrication is a pulsed laser processing. Aqueous and organic electrolytes can be used.
Our high energy supercapacitor can be used in grid stabiization, reali transport, EV fast charging, industrial equipment starting and electric aviation.
