固态聚合物电解质(SPE)是下一代安全电池系统的潜在材料,但SPE不能同时保持较高的机械强度和离子传导率,使下一步研究进入瓶颈.在此,我们通过原位点击反应在静电纺丝聚酰亚胺(PI)膜上制备了一种具有交联结构的聚醚硫醚电解质,厚度仅为19...固态聚合物电解质(SPE)是下一代安全电池系统的潜在材料,但SPE不能同时保持较高的机械强度和离子传导率,使下一步研究进入瓶颈.在此,我们通过原位点击反应在静电纺丝聚酰亚胺(PI)膜上制备了一种具有交联结构的聚醚硫醚电解质,厚度仅为19μm.由于烯-巯网络的交联结构和静电纺丝PI膜的增强作用,该SPE膜在60℃下具有135 MPa的储能模量,2.24×10^(-4)S cm^(-1)的离子传导率和4.0 V的电化学稳定窗口,并且锂-锂对称电池在0.1 m A cm^(-2)下循环超过800 h,展现出了优异的循环稳定性.用该超薄聚合物电解质膜组装的LiFePO_(4)/Li电池在60℃,0.5 C下能够循环超过250圈.这项工作开发了一种用于固态高性能锂金属电池的新型聚合物电解质.展开更多
