Owing to its unique excellent physical properties and conductive properties, porous polymers is one of the important parts for designing and fabrication of new energy materials. The ion-exchange ability of the ionic porous polymer, which can as excellent ion-exchange materials, has been exemplified in the energy conversion and storage field.. In this project, Using design and tailoring functhion of viologen molecules, the polymerization of viologen-based porous polymer (CPV) act as the precursor, to be precisely tuned in the composition and structure of CPV. Furthermore, various types of metal oxide and carbide composites will be in situ synthetized through ion-exchange of different types of precursor. The porous carbon composites will be achieved by the pyrolysis of the CPV-based materials under N2 atmosphere. So as to achieve porous of the molecular level, as well as the control of its morphology, particle size distribution, and specific surface area. The electrochemical performance of the CPV-basede of the CPV-based composites as electrode materials will be investigated，and the relation among composition structure-surface morphology-properties will further be revealed, which provide the basis for the design of high performance electrodes materials. The project not only enriches the research field of solid materials chemistry, but also further promotes the application of polyoxometalate, which has important theoretical and practical significance.
