摘要：锂硫电池因具有高能量密度而受到了国内外的广泛关注。粘结剂是锂硫电池中辅助组件的核心材料之一,是电极制作过程中必不可少的关键材料。该文介绍了锂硫电池中抑制聚硫离子穿梭的粘结剂、稳定电极片的多维度粘结的粘结剂和面向低界面电阻的粘结剂,重点阐述了它们的分子结构设计和粘结机制,并说明了各自的构效关系。通过分子结构设计可以获得多功能粘结剂,该类粘结剂能有效提高锂硫电池的充放电容量和循环寿命。最后指出,在合成此类多功能粘结剂材料时,需合理地利用官能团与聚硫离子的相互作用,重点应集中在水性多功能粘结剂的研究和应用范围拓展上。
Lithium-sulfur(Li-S)batteries have attracted considerable attention due to their superior theoretical energy density.Multifunctional binders as an indispensable material in the process of making electrode are one of the core materials of auxiliary components in Li-S batteries.In this paper,the multifunctional binders that inhibit polysulfide shuttles,the binders that stabilize multidimensional bonds of entire electrode and the binders had low interfacial resistance are introduced.The molecular structure design and binder mechanism of the binders are emphasized.Their structure-activity relationship is also explained.Advanced multifunctional binders can be obtained by molecular structure design,and these binders can effectively improve the charging and discharging capacity and cycle life of lithium sulfur battery.Hence,the interactions between functional groups and polysulfide ions should be reasonably utilized in the synthesis of such multifunction binder materials.Moreover,the research emphasis of binder for Li-S batteries should focus on the research and application of water-based multifunctional binder.
