High energy supercapacitor development
CRRC QINGDAO SIFANG ROLLING STOCK RESEARCH INSTITUTE CO.,LTD (Qin Ruijie) / CSIRO (Graeme Snook)
This project investigated the use of supercapacitors as a high-power energy storage device to power light rail. Following on from the Supercapacitor Energy Management System project, this work focused on developing high energy supercapacitors with new design and chemistry.

- The development of high power, high energy supercapacitors with high cycle life required careful consideration of the fast charge catenary-free application, due to the inevitable trade-off between high power density, high energy density and cycle life.
- The resulting device met target parameters with a novel anode and cathode configuration. Further work was proposed by CSIRO to reduce the internal resistance of the cell – a parameter which is required to reduce heating of the cell during charging and discharging.
- As part of this project, a CRRC employee completed a PhD at Queensland University of Technology with supervision from both QUT and CSIRO. The PhD successfully studied Lithium Metal Phosphates and the mechanism of electronic conductivity.
