生物质炭材料在双电层电容器中的应用

Application of biomass-based carbon materials for electrochemical double-layer capacitors

双电层电容器电极材料一般由炭材料组成,随着化石能源的日益枯竭和环境污染的逐步恶化,传统炭材料的生产和应用受到了挑战。采用绿色环保的生物质作为碳源,制备双电层电容器电极材料已成为研究热点之一。介绍了近几年来生物质炭材料的制备及其在双电层电容器中的应用进展,综述了生物质前驱体和制备方法对双电层电容器电化学性能的影响。

By the consuming of chemical energy and deteriorating of environment,even though the electrode of electrochemical double-layer capacitors（EDLC） always consist of carbon materials,the production and application for traditional carbon materials have been challenged.Therefore,using biomass-based materials as precursor to prepare porous carbon has become a hot topic for EDLCs.The preparation and application progress of the biomass-based carbon materials were introduced.The influence of different raw materials and preparation methods on electrochemical properties was reviewed.
