PhD topic – Hybrid supercapacitors with high energy and power densities for rail industry applications
This research aimed to develop a hybrid supercapacitor with high energy and power densities and advanced supercapacitor management systems for rail. The implementation of this new supercapacitor technology could effectively provide voltage stabilisation for rail systems, and improve the performance of propulsion for light rail vehicles.
- We have synthesized several electrode materials for hybrid supercapacitors.
- The electrode materials show high power and energy densities.
- In addition, the synthetic method is facile to be enlarged, demonstrating great potential for practical rail industry application.
