Hongqiang Xu specialises in all-solid-state lithium batteries, with a focus on electrode materials, solid-electrolyte interfaces, and the structural and electrochemical mechanisms governing ion and electron transport.

Hongqiang Xu is a PhD researcher at the Australian Institute for Bioengineering and Nanotechnology at The University of Queensland. His research focuses on the development and mechanistic understanding of electrode materials and interfaces for all-solid-state lithium batteries. In particular, he investigates mixed ion–electron conducting cathode materials, with the aim of enabling electrochemical reactions with reduced reliance on conductive carbon and solid-electrolyte additives. His work combines materials synthesis, electrochemical testing, structural and spectroscopic characterisation, synchrotron-based techniques, and first-principles calculations to understand how local structure, redox chemistry, lithium transport, electronic transport, and interfacial reactions collectively determine battery performance. He is also interested in developing general design principles for stable, high-capacity and practically relevant solid-state battery materials.

Industry

Research interests are relevant to battery materials development, solid-state energy storage, and advanced materials characterisation.

Collaborations

Hongqiang Xu collaborates with researchers within the Australian Institute for Bioengineering and Nanotechnology and across The University of Queensland on the synthesis, electrochemical evaluation, structural characterisation and computational investigation of solid-state battery materials. He also works with facility scientists at the Australian Synchrotron on synchrotron-based X-ray diffraction and spectroscopy experiments, supporting the investigation of local structure, electronic structure and interfacial chemistry in battery materials.
