Gel polymer electrolytes (GPEs) have attracted abundant attentions due to its higher ion conductivity and better compatibility with electrode than the inorganic solid-state electrolytes and safer than the liquid electrolytes. In this work, sodium conductive Na₃Zr₂Si₂PO₁₂ nanoparticles modified PVDF-HFP/PMMA/TPU-based GPEs are prepared and its application performances in sodium ions batteries (SIBs) are demonstrated. The addition of Na₃Zr₂Si₂PO₁₂ filler decreases the crystallinity of polymer matrix and improves the porosity of GPEs membranes, resulting in the increasing of liquid electrolyte uptake. As a result, the Na₃Zr₂Si₂PO₁₂ filler modified GPEs delivers enhanced ion conductivity as high as 2.83 × 10⁻³ S cm⁻¹ with a small activation energy of ~0.039 eV and enlarged electrochemical window width of 5.16 V. Application in SIBs, high first discharge capacity of 92.7 mAh·g⁻¹ at 0.5C and promising capacity retention capability (99.2% after 100 cycles) as well as excellent rate performance (83.9 mAh·g⁻¹ at 5C) are recorded for the obtained GPEs. These results suggest that the performances of PVDF-HFP/PMMA/TPU-based GPEs can be enhanced obviously by adding conductive Na₃Zr₂Si₂PO₁₂ filler, promoting the practical application of GPEs in energy storage devices.

凝胶聚合物电解质（GPE）由于其离子电导率高，与电极的相容性比无机固态电解质好并且比液体电解质更安全，因此备受关注。本文制备了钠导电的Na ₃ Zr ₂ Si ₂ PO ₁₂纳米颗粒改性的PVDF-HFP / PMMA / TPU基GPE，并证明了其在钠离子电池（SIB）中的应用性能。Na ₃ Zr ₂ Si ₂ PO ₁₂填料的添加降低了聚合物基体的结晶度，并改善了GPEs膜的孔隙率，从而增加了液体电解质的吸收。结果，Na ₃Zr ₂ Si ₂ PO ₁₂填料改性的GPE提供增强的离子电导率，高达2.83×10 ^-3  S cm ^-1，活化能小至〜0.039 eV，电化学窗口宽度扩大至5.16V。 92.7毫安的容量·克^-1以0.5C和有前途的容量保持能力（100次循环后99.2％）以及优异的倍率性能（83.9毫安·克^-1在5℃）被记录为所获得的GPES。这些结果表明，通过添加导电的Na ₃ Zr ₂ Si ₂ PO ₁₂可以明显提高PVDF-HFP / PMMA / TPU基GPE的性能。 填充剂，促进了GPE在储能设备中的实际应用。
