近日,我校学院高性能功能材料与器件创新团队刘淑玲教授及王超副教授围绕电化学储能材料及电催化材料设计领域取得多项重要进展,连续在Chemical Engineering Journal(IF = 16.744),Journal of Power Sources(IF = 9.794), Applied Surface Science(IF = 7.392), Electrochimica Acta (IF = 7.336)等国际知名期刊发表12篇研究论文。
这些研究工作主要涉及锂离子电池/水系超级电容器高性能电极材料及水电解制氢新型催化剂的设计与开发。针对锂电电极/水系超级电容器电极材料面临的容量低、稳定性差的问题,团队主要通过界面调控及优化、异质结构设计等策略构建高性能电极材料,提升了材料导电性,增加了储离子位点,并抑制充放电过程中的不可逆相变,有效提升了材料储能容量及循环稳定性(Dual-layer carbon protected coaxial cable-like Si-based composites as high-performance anodes for lithium-ion batteries; A facile synthesis of Ni0.85Se@Cu2−xSe nanorods as high-performance supercapacitor electrode materials)。针对水电解制氢过程中,析氧反应动力学缓慢,需要极高过电势的问题,团队采用无定型/结晶态异相结构设计、掺杂等策略,增加电化学活性位点数量,优化析氧中间体吸附能,加速析氧反应动力学过程(Solvothermal preparation of nickel-iron phosphides hollow nanospheres derived from metal-organic frameworks for water oxidation reaction; Electrodeposited amorphous cobalt-nickel-phosphide-derived films as catalysts for electrochemical overall water splitting)。这些研究成果极大地扩展了高性能储能材料/电催化剂的开发,推动了相关产业的发展。
