Invited by Prof. Huaiyu Shao, Prof. Hong Guo (郭洪) from Yunnan University, visited IAPME and gave a talk on 4 August 2025.
Prof. Guo received his Ph.D. degree at the University of Science and Technology Beijing in 2008, and obtained the nomination of national outstanding doctorate dissertation. He was a visiting scholar in State Key Laboratory of Fire Science in Japan from October 2002 to September 2004. Prof. Guo has been appointed as a Professor in School of Chemistry Science and Engineering at Yunnan University by Talents Introduce Project in 2010. He was a visiting scholar at Western University in Canada from September 2016 to October 2017. Prof. Guo serves as Fellow of the Vebleo, a member of a council of the Chinese society of silicate solid ion branch, a member of the electrochemical society (ISE), a member of a council of the International Academy of Electrochemical Energy Science (IAOEES), and obtained the Science and Technology Award in Yunnan province.
Prof. Guo delivered a seminar titled “Design Strategies for In Situ Polymerized Gel Composite Electrolytes”. His talk focused on DOL-based gel polymer electrolytes (GPEs) for solid-state batteries via multidimensional optimization. In-situ polymerized PDOL with an interfacial inducer formed a stable CEI/SEI bilayer, enabling long-cycle Li and NCM811 cells. Incorporating titanium-based MOFs as scaffolds boosted mechanical strength and Li⁺ transport (ionic conductivity 1.36×10⁻³ S cm⁻¹; Li⁺ transference number: 0.71). Further, integrating Co-Ti bimetallic MOFs via combined processes created a redox potential gradient, achieving 97% Li utilization and high capacities in NCM90/LFP cells (e.g., 198.8 mAh g⁻¹ at 1C). In-situ studies confirmed suppressed inactive Li⁰ and enhanced kinetics, providing a design pathway for high-energy-density SSBs. In the Q&A session, Prof. Guo had zealous interaction with the audience.
During the visit, Prof. Guo joined a IAPME lab tour, had close discussion with some professors and PhD students, and also expressed deep impression on IAPME’s research facilities and achievements.
