先进CHS结构柔性复合负极材料的可控制备及其储能构效关系研究

为了满足未来社会便携式电子器件的应用需求，电极不但要有较大的能量密度和功率密度，还要有良好的柔韧性和可加工性，能否开发出高性能柔性储能器件，是柔性电子产品广泛应用的关键之一。本项目选用轻质柔性发泡碳材料作为集流体，利用ALD法、置换法和二次水热法等来构建先进CHS结构复合电极，通过对该材料中物质和能量的输运、异质界面的交互作用、纳米材料在外场中的响应研究基础上，掌握多元CHS先进电极设计可控制备的关键技术，找到一些结构与物性的定量关系，提炼出普适的结构物性规律，从一个更深的层次来解析电极材料中的纳米结构单元在生长过程中的演化规律及其与电化学性能之间的关系。本项目首次提出轻质柔性CHS结构复合电极材料的设计及构效关系探究，相信随着研究的深入，更多性能优异、结构新颖的柔性电子产品将得以实现。

In order to satisfy the application requirement of portable electronic devices of the future society, the materials of electrode have not only the larger energy density and power density, but also has the good flexibility and machinability, if the high performance flexible energy storage does not to develop device, it will the key to the flexible electronic products are widely used.This project choose lightweight flexible foam carbon materials as a collection of fluid, using the method of ALD, displacement method and secondary water hot method to build advanced CHS composite electrode structure,based on the material and energy transport, heterogeneous interfacial interaction, the response of nanomaterials in the field of study, the key technologies to be found through multiple advanced CHS electrode was design, the structure of the extracted universal property law, from a deeper level to parse the electrode material of nano structural unit in growth in the process of evolution and the relationship between the electrochemical performance. The project is the first time to present the CHS structure design of lightweight flexible composite electrode materials and the structure-property relationship; we believe that the flexible electronics will be realized which has more excellent performance, novel structure with the deepening of the research.
