| 摘 要： | 采用聚碳酸亚丙酯(PPC)、偏氟乙烯-六氟丙烯共聚物(P(VDF-HFP))、双三氟甲烷磺酰亚胺锂(LiTFSI)、磷酸钛铝锂(Li_(1.4)Al_(0.4)Ti_(1.6)(PO_4)_3)和锂离子电池三元电解液(1 mol·L~(-1)LiPF_6的碳酸乙烯酯(EC)-碳酸二甲酯(DMC)-碳酸甲乙酯(EMC)溶液,V_(EC)∶V_(DMC)∶V_(EMC)=1∶1∶1)制得准固态复合电解质,其中液态电解质含量为9%(w/w)。准固态复合电解质膜在25℃下电导率达1.3×10~(-4) S·cm~(-1)。与LiFePO_4组装成准固态锂电池,0.5C倍率下首次放电比容量达128.4 mAh·g~(-1),充放电50次后容量保持率为80%。与纯聚合物准固态电解质相比,添加Li_(1.4)Al_(0.4)Ti_(1.6)(PO_4)_3可显著降低界面电阻。
