Recently, Professor Zhouguang Lu from the Department of Materials Science and Engineering (MSE) at the Southern University of Science and Technology (SUSTech) reported a simple yet straightforward strategy to improve the cycling stability of ultra-high voltage LiCoO2 at 4.6V. This study, entitled “Dextran sulfate lithium as versatile binder to stabilize high-voltage LiCoO2 to 4.6 V,” was published in Advanced Energy Materials, a high-profile journal in material science.

Recently, Professor Meng Gu from the Department of Materials Science and Engineering (MSE) at the Southern University of Science and Technology (SUSTech) and Professor Joseph S. Francisco from the Department of Chemistry at the University of Pennsylvania (UPenn) collaborated to report an iridium single-atom on Ni2P catalyst (IrSA-Ni2P) with a record low overpotential of 149 mV at a current density of 10 mA·cm−2 in 1.0 M KOH. Their study, entitled “Single Iridium Atom Doped Ni2P Catalyst for Optimal Oxygen Evolution,” was published in the high-impact journal Journal of the American Chemical Society.

Stoichiometry has a very important effect on the properties of oxides. Taking vanadium dioxide (VO2) as an example, the increase of oxygen vacancies significantly decreases the phase transition temperature from high-temperature metallic tetragonal R phase to low-temperature insulating monoclinic M1 phase. At the same time, excess oxygen can effectively stabilize two metastable insulating phases, the monoclinic M2 phase and the triclinic T phase. Up to date, there are still many difficulties in the fine regulation of oxygen content in oxides, which is a very important and challenging research topic.

Recently, Professor Hui Li’s group from the Department of Materials Science and Engineering, at the Southern University of Science and Technology (SUSTech), published a review paper in Nature Energy, entitled “Bridging the gap between highly active oxygen reduction reaction catalysts and effective catalyst layers for proton exchange membrane fuel cells”. This review discusses the performance discrepancy between ex-situ thin-film rotating disk electrode (RDE) and real membrane electrode assembly (MEA). Furthermore, it elucidates various intrinsic limitations that have resulted in a persistent failure to transfer the high RDE activities of catalysts into maximized energy output at the MEA level.

Recently, Professor Hsing-Lin Wang from the Department of Materials Science and Engineering and Professor Haiping Xia from the Department of Chemistry at the Southern University of Science and Technology (SUSTech) made significant progress on the research of cathode interfacial materials (CIL) in perovskite solar cells (PSCs), leading to a publication in the Journal of American Chemical Society (JACS), which was also selected as the front cover.

Superelastic materials capable of recovering large nonlinear strains are ideal for various applications in morphing structures, reconfigurable systems, and robots. However, making oxide materials superelastic has been a long-standing challenge due to their intrinsic brittleness. The only macroscopically brittle oxide recently discovered to be superelastic is ZrO2-based micropillars or particles, which are realized via austenite-martensite phase transformation. Although ultimate strengths approaching the theoretical limit have been demonstrated in nanoscale samples, long fatigue life is elusive, which is arguably more important for most applications. Poor fatigue life has been a long-standing challenge for oxide ceramics in general.
