摘要:纳米纤维素表面含有大量羟基且长径比高，具有较好的润湿性和分散电活性材料的能力，是一种较好的电极材料基底，可作为超级电容器电极材料的优先选择。但是其缺点在于导电性不高，需要加入导电材料进行提升。本文归纳了纳米纤维素基水凝胶电极的分类，探讨了纳米纤维素基水凝胶电极的合成方法，对比分析了不同导电材料的纳米纤维素基水凝胶电极的电化学性能，并对其在未来应用领域的发展前景进行了展望。

Abstract:Nanocellulose has a large number of hydroxyl groups on the surface and high aspect ratio. It has good wettability and the ability of dispersing electroactive materials. It is a good electrode material substrate， and can be used as the preferred electrode material for supercapacitors. However， the disadvantage of its low conductivity leads to the need for compositing with conductive materials. In this paper， the classification of nanocellulose-based hydrogel electrodes was summarized， the synthesis methods of nanocellulose-based hydrogel electrodes were discussed， the electrochemical properties of nanocellulose based hydrogel electrodes with different conductive materials were compared and analyzed， and their development prospects of application fields in the future were prospected.
