New hierarchical electrode design for high-power lithium ion batteries (ARC Discovery Project administered by Griffith University) (2018-2021)

Effective energy storage system plays an important role in the development of renewable energies and electric vehicles. This project aims to develop new types of hierarchical electrodes for high-rate lithium ion batteries with long cycling life. The key concepts are the development of multi-shelled hollow structured silicon-based anode and Li-rich layered oxides cathode to achieve both high power and energy density, and the adoption of graphene to further improve rate capability and cycling stability. The outcomes will lead to innovative technologies in low carbon emission transportation and efficient energy storage systems.
