All-solid-state lithium-ion batteries constructed with solid-state electrolytes have extremely high safety and reliability, which are an existing research hotspot in lithium-ion batteries. It is thus a great significance to develop inorganic-polymer composite solid electrolytes. In this paper, Li7La3Zr2O12 (LLZO) nano-powders were prepared by a sol-gel and ball milling method. Also, a solid-state composite polymer electrolyte with LLZO as an active filling material and polyethylene oxide (PEO) blended with polyethylene partial fluoride (PVDF) was prepared by a solution pouring method. The samples were characterized by field emission scanning electron microscopy and X-ray diffraction. The results show that LLZO/PEO/PVDF solid-state composite polymer electrolyte (SCE) membrane with 10% (in mass fraction) LLZO has a high ionic conductivity (8.93×10-5 S/cm) and a stable electrochemical window (4.9 V). The rate capabilities and cycle performance of LiFePO4/Li all-solid-state lithium battery with 10%LLZO both are improved. At 60 ℃, the capacity recovery rate is 99.4%, and the capacity retention rate after 100 cycles is 84.1% at 0.2 C.

以固态电解质构建的全固态锂离子电池具有极高的安全性及可靠性，是目前锂离子电池领域的研究热点，其中研发无机物-高分子复合固体电解质用于全固态锂离子电池具有重要意义。通过溶胶-凝胶法及球磨细化制备了纳米级Li7La3Zr2O12（LLZO）粉末，进而采用溶液浇注法制备出以LLZO为活性填料，聚氧化乙烯（PEO）和聚偏氟乙烯（PVDF）共混的固态复合聚合物电解质。通过场发射扫描电子显微镜以及X射线衍射仪对材料的形貌、物相及电化学性能表征表明：添加质量分数为10%LLZO的LLZO/PEO/PVDF固态复合聚合物电解质具有高离子电导率（8.93×10-5 S/cm）以及稳定的电化学窗口（4.9 V）。添加LLZO之后的LiFePO4/Li全固态电池的倍率性能以及循环性能均得到提高，在60 ℃高温下，容量恢复率为99.4%，0.2 C循环100圈后容量保持率为84.1%。

以固态电解质构建的全固态锂离子电池具有极高的安全性及可靠性，是目前锂离子电池领域的研究热点，其中研发无机物-高分子复合固体电解质用于全固态锂离子电池具有重要意义。通过溶胶-凝胶法及球磨细化制备了纳米级Li7La3Zr2O12（LLZO）粉末，进而采用溶液浇注法制备出以LLZO为活性填料，聚氧化乙烯（PEO）和聚偏氟乙烯（PVDF）共混的固态复合聚合物电解质。通过场发射扫描电子显微镜以及X射线衍射仪对材料的形貌、物相及电化学性能表征表明：添加质量分数为10%LLZO的LLZO/PEO/PVDF固态复合聚合物电解质具有高离子电导率（8.93×10-5 S/cm）以及稳定的电化学窗口（4.9 V）。添加LLZO之后的LiFePO4/Li全固态电池的倍率性能以及循环性能均得到提高，在60 ℃高温下，容量恢复率为99.4%，0.2 C循环100圈后容量保持率为84.1%。

All-solid-state lithium-ion batteries constructed with solid-state electrolytes have extremely high safety and reliability, which are an existing research hotspot in lithium-ion batteries. It is thus a great significance to develop inorganic-polymer composite solid electrolytes. In this paper, Li7La3Zr2O12 (LLZO) nano-powders were prepared by a sol-gel and ball milling method. Also, a solid-state composite polymer electrolyte with LLZO as an active filling material and polyethylene oxide (PEO) blended with polyethylene partial fluoride (PVDF) was prepared by a solution pouring method. The samples were characterized by field emission scanning electron microscopy and X-ray diffraction. The results show that LLZO/PEO/PVDF solid-state composite polymer electrolyte (SCE) membrane with 10% (in mass fraction) LLZO has a high ionic conductivity (8.93×10-5 S/cm) and a stable electrochemical window (4.9 V). The rate capabilities and cycle performance of LiFePO4/Li all-solid-state lithium battery with 10%LLZO both are improved. At 60 ℃, the capacity recovery rate is 99.4%, and the capacity retention rate after 100 cycles is 84.1% at 0.2 C.
