Abstract Solid‐state sodium metal batteries (SSMBs) are considered as one highly competitive, high‐energy‐density yet safe energy storage device, however, the conventional quasi‐solid‐state electrolytes (QSSEs) still suffer from low ion conductivity and limited mechanical properties. Herein, a safe, fast‐charging, long‐life SSMB is reported, utilizing photopolymerized ethoxylated trimethylpropane triacrylate based QSSEs (BN‐QSSE) reinforced by 2D functional fillers of boron nitride nanosheets (BNNSs). The BNNSs with high Young's modulus in BN‐QSSE can simultaneously accelerate homogenize transport for uniform Na deposition form robust electrolyte‐Na interface.
