纳米能源复合材料
在能源与环境并重的时代,新能源材料与器件在清洁能源的综合利用中发挥着重要的作用,成为当前社会经济发展的重大需求和科学技术的前沿。本课题组围绕新能源材料的设计合成、电化学过程的机制研究、新能源存储与转换器件等方面开展了系统研究,尤其是高效光/电催化材料与器件、锂/锌二次电池、超级电容器、柔性可穿戴器件的设计与开发。 1. 新能源材料基元设计合成 通过小分子调控策略和一锅两步的晶种策略设计合成了组分、尺寸、晶体结构以及表面微观结构等可控的新能源纳米材料,为开发新型、高效、稳定的新能源材料奠定了理论和实验基础。
2. 新能源转换与存储机理研究 针对电解水制氢、氮气还原制氨等新能源转换反应过程,及锂/锌二次电池等新能源存储反应过程,我们从纳米尺度和表面结构出发,利用原位红外/拉曼光谱等原位表征手段,揭示新能源材料在电化学反应过程中的机理,为其实际应用提供理论基础。 3. 新能源转换/存储器件 针对传统二次电池能量密度低、安全性差等问题,通过“固柔结合”及“原位聚合”等策略发展高性能固态电解质材料,并优化电极/电解质界面,以开发兼备高安全性、高电化学性能和低成本的电池体系。
