New generation lithium-ion batteries with high energy and long service life for rail industry applications
HEC Group (Steven Wan) / University of Technology Sydney (Guoxiu Wang)
This research was focused around developing new anode and cathode materials for lithium ion batteries, with the potential to enable higher energy density and a longer cycle life. This could be used for propulsion and enabling regenerative braking of the train, signalling systems and auxiliary applications such as the train’s air conditioning and back-up power needs.
1 January 2017 to 31 December 2019
Total contracted budget (including in-kind)
- The research group developed lithium rich cathode materials, showing improvements compared with the energy density of commercial NCM materials and with a cycle life of over 3,000 cycles at lab scale.
- Anode materials utilising silicon/graphite and lithium titanate demonstrated the energy density of these materials with stability of the anode increased by using additives.
- Importantly, the solid-state processing route for producing the materials was compatible with the industrial scale processing equipment currently used for battery materials.
