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)

New generation lithium-ion batteries with high energy and long service life for rail industry applications

Research summary

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.

Start/end date

1 January 2017 to 31 December 2019

Total contracted budget (including in-kind)

$4,816,560

Key achievements

  • 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.
