PhD topic – New generation lithium-ion batteries with high energy and long service life.

Research summary

This research is focused around developing new anode and cathode materials for lithium ion batteries, which could enable higher energy density and a longer lifecycle, used for propulsion and enabling regenerative braking of the train, signaling systems and auxiliary applications such as the train’s air conditioning and back-up power needs.

Expected completion date

August 2021

Key achievements

• Successfully improving the electrochemical performance of carbon/Silicon composite anode for next generation Li-ion batteries.
• Successfully improving the initial coulombic efficiency of Si anode and improve the working life span of Li ion batteries.
• Reducing the cost of next generation Li ion batteries.
