, 2011 本发明公开了一种制备锂离子电池用聚阴离子型正极材料的溶胶-凝胶方法。首先将锂盐、过渡金属盐、聚阴离子前驱物和碳源按照一定的化学计量比混合制成溶胶；然后在一定条件下加入有机环氧化物制成凝胶；经干燥、煅烧后制得最终产物—聚阴离子型正极材料。该方法简单、易操作；反应物混合更均匀，凝胶易形成；与固相合成法相比，降低了煅烧温度和煅烧时间；与其它溶胶-凝胶方法相比，该方法成胶快，合成时间大为缩短，适合工业化生产。利用该方法合成的聚阴离子型正极材料具有粒径小、分布均匀、比表面大等优点；特别是材料还具有良好的充放电性能、

, 2017 以N，N-亚甲基双丙烯酰胺为交联剂，先通过光引发聚合制备聚丙烯酰胺水凝胶内嵌聚苯乙烯胶体晶体的聚合胶体晶体（PCC），再将PCA2与氯化1-烯丙基-3-甲基咪唑离子液体进行溶剂置换，制备了离子液体聚合胶体晶体（ILPCC）。采用反射光谱研究了制备过程中聚合胶体晶体结构的变化，考察了ILPCC的压力响应性和压缩性能。研究表明，离子液体使胶体晶体的带隙先蓝移后红移，达到平衡时带隙红移220nm以上。离子液体显著改善了聚合胶体晶体的存储稳定性和压缩性能 ...
