研究了基于新型凝胶聚合物电解质和取代尖晶石正极的锂聚合物电池的电化学性能。以碳酸丙烯酯（PC）和聚乙二醇硼酸酯（PEG-BE）为增塑剂，制备了聚乙二醇甲基丙烯酸酯（PEG-Ms）/LiClO 4聚合物电解质。该电解质具有良好的热稳定性、机械稳定性和电化学稳定性。基于Li/PC/PEG-BE的聚合物电解质/LiMn 1 . 8 CO 0 . 2 O 4电池在室温下具有相当稳定的容量，在65°C下具有相当大的倍率性能
The electrochemical performance of a lithium polymer battery based on a novel gel polymer electrolyte and a substituted spinel cathode was investigated. Propylene carbonate (PC) and poly(ethylene glycol)-borate ester (PEG-BE) were used as plasticizers in the polymer electrolyte composed of poly (ethylene glycol) methacrylates (PEG-Ms) and LiClO 4 . The electrolyte exhibited satisfactory thermal, mechanical, and electrochemical stability. The Li/PC/PEG-BE based polymer electrolyte/LiMn 1 . 8 co 0 . 2 O 4 cell generated a reasonable steady capacity at room temperature and a substantial rate capability at 65°C.
