O3-type layered oxide materials are attractive materials for cathode fabrication for commercial sodium-ion batteries (SIBs). However, their electrochemical performance and practical viability are hindered by rapid capacity decay—driven by severe phase transitions and air/moisture sensitivity. Herein, multielement codoped O3-type layered oxide materials NaLi0.05Ni0.3Mn0.5₋xCu0.1Mg0.05SnxO2 (x = 0, 0.01, 0.03, 0.05) were synthesized using a simple spray-drying method. These mat

Silicon suboxide (SiOx) is a promising anode material for next-generation lithium-ion batteries because of its high capacity and structural stability. However, its practical application is severely limited by substantial irreversible lithium consumption during the first cycle, making effective prelithiation essential for improving the initial Coulombic efficiency (ICE). Although direct-contact prelithiation provides a simple approach for lithium compensation, controlling lith

A great BBQ gathering to recharge before the final push toward midterm exams! It was wonderful to welcome our alumni back to the lab and give our new members a chance to get to know everyone better. Good food, great company, and plenty of energy for the challenges ahead!

Honored to attend the 2026 Academic Awards Recognition Ceremony at National Yang Ming Chiao Tung University (NYCU). My sincere gratitude to the President and the Office of Research and Development for their recognition and encouragement. I am also grateful to my research team and collaborators for their continued dedication and support. I look forward to further advancing our research and fostering the next generation of researchers.

The practical viability of small-molecule organic anodes is often limited by active material dissolution and the accompanying interfacial instability in liquid electrolytes. Herein, we investigate how functional group chemistry influences Li/Li+ interactions, dissolution behavior, interfacial evolution, and electrochemical accessibility in naphthalene-derived organic anodes. Using naphthalene as a model framework, we systematically compare hydroxylated and carboxylated deriva

Thermal effects are known to influence lithium deposition behavior and interfacial reactions; however, their role in regulating the evolution of lithium interfaces in electrochemical cells remains insufficiently understood. In this work, a thermal-conditioning strategy was applied to lithium symmetric cells to investigate its influence on voltage stability and interfacial evolution. Preheating at 90 °C delayed the onset of voltage instability, while postheating restored volta
