1. Synthesis and developments of high-energy layered oxide cathodes for advanced lithium-ion batteries

Cathode materials are one of the most critical parts of lithium-ion batteries as they primarily determine the energy density and cost of LIBs. We aim to develop advanced high-energy layered oxide cathode materials including Ni-rich NMC, Li-rich oxide cathodes, and single crystal cathodes to achieve high capacity and stability of LIBs. Our research particularly focuses on a fundamental understanding of the synthesis of layered cathode materials and their degradation behaviors during operando by using advanced characterizations. We also develop the measurements and evaluation platforms for the battery cathode materials and their recycling/regeneration technologies for global standardization.

2. Developments of next-generation batteries

To overcome the limitations of current lithium-ion batteries, our research aims to develop various post-lithium-ion batteries including solid-state batteries, organic batteries, and lithium-metal batteries (anode-free batteries). Specifically, we are focusing on the synthesis, fabrication, and evaluation of solid-state oxide electrolytes and electrode-electrolyte interface engineering to develop solid-state batteries as a promising post-LIB with high energy and safety. We also aim to develop sustainable high-energy electrode materials including organic electrodes and lithium metal electrodes by means of materials and interface engineering (nano-hybridization etc.).

3. Multiscale and advanced characterization of battery materials

Our research aims to develop and establish multiscale evaluation platforms of battery systems to understand the complex and hierarchical structure of batteries ranging from single particle, electrode to battery cells level. We also develop advanced analysis tools to probe chemical and structural changes in battery materials in real-time (in-situ X-ray diffraction and Raman spectroscopy, etc.).
