英文摘要： This project will systematically investigate the key fundamental issues in the development of high performance germanium based flexible electrode, explore and summarize the electrochemical reaction mechanism and reaction rules,in order to overcome the key technology bottleneck for the future development. The topics include two main parts, the first one is the design, prediction and controllable preparation of novel germanium based electrode materials, the second one is the detail characterization of selected electrode materials, deeply study of their charge transfer mechanism. Investigation of the electrochemical reaction mechanism and the relationship between materials's structure and performance during charge and discharge process. It is supposed to uncover the correlation of preparation condition, material structure, and device performance through analysis of experimental data. They are useful to supply evidences theoretically and experimentally for optimization of flexible electrochemical cells and promotion of electrochemical energy storage technologies. The research outcomes of this project will provide important theoretical and technical guides to the future development and research of germanium based flexible electrode with self-owned intellectual property rights.
