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. Effective energy storage systems play an important role in the development of renewable energies and electric vehicles. The project outcomes will lead to innovative technologies in low carbon emission transportation and efficient energy storage systems.
