郭向欣,男,19731月生,山东济宁人。中国科学院百人计划杰出海外人才和上海市浦江人才,山东省泰山学者特聘教授,青岛市创业创新领军人才。无机材料学报和储能科学与技术编委,固态离子学理事。博士,教授,博士生导师。

郭向欣教授多年来的研究工作一直聚焦制约高能量密度金属锂二次电池发展的瓶颈问题,通过核心材料的设计构筑、先进技术的表征和分析,力图清晰显示并阐明影响电池性能的动力学及热力学机制,进而利用材料表界面物相组成和电荷分布的设计提高界面离子输运与反应速率、实现电池体系性能的显著提升。近年来在氧化物固体电解质尤其是石榴石型固体电解质及其固态电池方面开展了系列研究工作并取得具有重要科学意义和应用价值的成果:(1)揭示体相结构与表面缺陷影响离子传输的关键机理,获得高性能氧化物电解质粉体的批量化制备技术;(2)发现晶界补锂结合气氛热压的先进制备方法,获得致密度和离子电导率国际领先的锂镧锆氧陶瓷电解质;在此基础之上,阐明金属锂负极与锂镧锆氧陶瓷电解质界面相互作用机理,获得固态电解质中克服锂贯穿问题的有效方案;(3)将渗流理论运用到有机无机复合电解质中,通过界面调控制备出性能优异的柔性固态电解质膜;构筑高容量固态复合正极材料,提出制备兼具高能量密度和高安全性固态锂电池的实用化方案。近五年发表SCI收录论文75篇以上(第一/通讯作者70篇以上),高被引文章9篇,其中包括Nat. Commun., Energy Environ. Sci., Adv. Mater., Adv. Energy Mater., Adv. Funct. Mater., Nano Energy, Energy Storage Mater., J. Phys. Chem. C, Appl. Phys. Lett., Phys. Rev.
