Description

八氯丙基-POSS/聚烯烃纺丝纤维凝胶聚合物电解质及制备 方法
技术领域
本发明属于凝胶聚合物电解质制备技术领域，涉及一种八氯丙基-POSS/聚烯烃纺丝纤维凝胶聚合物电解质及制备方法。
背景技术
随着各种便携式电子设备的推广普及，作为其关键部件之一的化学电源也受到了越来越多的关注。由于具有比镍氢、镉镍电池更高的工作电压、更大的容量以及无记忆效应等优点，锂离子电池(LIB)应用领域已经从各种便携式用电设备迅速扩大到混合动力(PHEV)和纯电动(EV)汽车中。但是，动力型LIB除了需要更高的电压、更大的功率以及更多的电量外，更需要关注安全性的问题。溶液浇铸法或相转换法制备的无机纳米粒子复合凝胶聚合物电解质由于其较好安全性而得到行业内的广泛关注，但是这种工艺制备的无机纳米粒子复合凝胶聚合物电解质中无机纳米粒子易团聚，分散性较差，进而会影响到电池的电化学性能，并且组装的电池还存在界面相容性差等问题。
静电纺丝方法制备凝胶聚合物电解质的方法简单高效，且由静电纺丝制得的聚合物纳米纤维的直径在几微米至几十纳米范围内，纤维膜具有完全互连的孔结构和高表面积的大孔隙率，进而具有较高的离子电导率，所以成为制备凝胶聚合物电解质的有效方法。静电纺丝凝胶聚合物电解质不但能解决液体电解质漏液、爆燃等安全问题，其中的聚合物还起着传导锂离子，阻隔电子传输、隔离正负极的双重作用。并且通过静电纺丝的方法可以将纳米粒子与聚合物通过溶液共混的方式相混合，在高电压纺丝的过程中使得纳米粒子分散的更均匀。但是目前静电纺丝凝胶聚合物电解质存在纺丝薄膜力学性能较差等问题，难以满足动力性LIB的装配要求。
笼型倍半硅氧烷(POSS)是一种新型的有机-无机杂化分子，以一个类似于SiO2的无机笼形内核为核心，该核具有高的热稳定性、抗氧化性和阻燃性等，硅顶点上共价键键合有机基团，为无机纳米粒子与有机材料提供良好的相容性，所以成为近年来纳米材料改性高分子材料热性能、力学性能的研究热点。近年来，POSS也被越来越多的用于太阳能、锂离子电池电池的电解质改性中。
