摘要

电解质的设计对于钠金属电池的技术迭代至关重要。本研究将 1,4-二氯-2-碘苯作为电解质添加剂引入到具有高离子电导率（30 ℃ 时为 3.96 × 10-3 S cm-1）的凝胶聚合物电解质（FS-GPE-DCIB-0.1 %）的原位聚合过程中。Na|FS-GPE-DCIB-0.1 %|Na 电池在 0.1 mA cm-2 的电流密度下可稳定循环 1000 小时以上。即使在 10C 温度下，NVP|FS-GPE-DCIB-0.1%|Na 电池在经历 6000 次循环后仍能保持 91.6% 的容量保持率。这项研究为钠金属电池的实际应用展示了巨大的潜力。

Superior gel polymer electrolyte for sodium metal battery with long-term cycling stability at elevated current density

The design of electrolytes holds paramount importance for technology iteration of sodium metal batteries. This study introduces 1,4-Dichloro-2-iodobenzene as an electrolyte additive into the in-situ polymerization process of an gel polymer electrolyte (FS-GPE-DCIB-0.1 %) with high ionic conductivity (3.96 × 10^-3 S cm⁻¹ at 30 ℃). The Na|FS-GPE-DCIB-0.1 %|Na battery demonstrates stable cycling for over 1000 h at a current density of 0.1 mA cm⁻². Even at 10C, NVP|FS-GPE-DCIB-0.1 %|Na battery can maintain a capacity retention rate of 91.6 % after undergoing 6000 cycles. This work demonstrates a promising potential for practical implementation of sodium metal battery.
