摘要
锂离子电池及相关下一代二次电池的新材料开发一直是国内外材料科学领域的研究热点.有机电极材料因其来源丰富、结构多样、化学性质可调和柔性等优势而备受关注.与传统的无机电极材料不同,有机化合物存在分子间/分子内各种相互作用,这些相互作用对有机电池的电化学性能会具有显著影响.本文主要介绍了课题组在有机电极材料上的部分研究进展,重点探讨了通过分子设计来调控分子间或分子内相互作用(主要包括氢键、π–π相互作用、离子–离子、偶极–偶极以及离子–偶极相互作用等),从而解决有机电极材料的关键瓶颈问题,为未来发展高性能有机电极材料提供一些参考.
The development of new materials for lithium-ion batteries and similar next-generation secondary batteries is one of the hottest topics in the field of materials science.Organic electrode materials have attracted much attention because of their rich resources,structural designability,molecular level controllability and flexibility.Different from traditional inorganic electrode materials,organic compounds have various intermolecular/intramolecular interactions,which undoubtedly could affect the electrochemical performances of organic batteries.This review mainly outlined our efforts to develop high-performance organic batteries through rational molecular design to adjust the intermolecular or intramolecular interactions,mainly including the hydrogen bonding,π–π,ion–ion,ion–dipole as well as the dipole–dipole interactions,so as to solve the key challenges in organic electrode materials.And some prospects are provided for the development of high-performance organic energy-storage materials in the future.
