Beschreibung
Zusammenfassung:	The invention provides a lignin-based ionic gel preparation method, which comprises: dissolving lithium lignosulfonate and a lithium salt in an organic solvent, adding an ionic liquid, fully stirring and uniformly mixing to obtain a composite solution, and removing the organic solvent to obtain the lignin-based ionic gel. The lignin-based ionic gel has the characteristics of good film-forming property, high ionic conductivity, wide electrochemical stability window, high lithium ion transference number, no liquid leakage, nonflammability and the like. 本发明提供一种木质素基离子凝胶的制备方法，将木质素磺酸锂和锂盐溶解在有机溶剂中，然后加入离子液体，充分搅拌混匀后，得复合溶液，将有机溶剂去除，从而得到木质素基离子凝胶。该木质素基离子凝胶具有良好的成膜性、高的离子电导率、宽的电化学稳定窗口、高的锂离子迁移数和无漏液不易燃等特点。
