Abstract
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.
