Development of high-performance sodium metal batteries (SMBs) with a wide operating temperature range (from -40 to 55 degrees C) is highly challenging. Herein, an artificial hybrid interlayer composed of sodium phosphide (Na3P) and metal vanadium (V) is constructed for wide-temperature-range SMBs via vanadium phosphide pretreatment. As evidenced by simulation, the VP-Na interlayer can regulate redistribution of Na+ flux, which is beneficial for homogeneous Na deposition. Moreover, the experimental results confirm that the artificial hybrid interlayer possesses a high Young's modulus and a compact structure, which can effectively suppress Na dendrite growth and alleviate the parasitic reaction even at 55 degrees C. In addition, the VP-Na interlayer exhibits the capability to knock down the kinetic barriers for fast Na+ transportation, realizing a 30-fold decrease in impedance at -40 degrees C. Symmetrical VP-Na cells present a prolonged lifespan reaching 1200, 500, and 500 h at room temperature, 55 degrees C and -40 degrees C, respectively. In Na3V2(PO4)(3)||VP-Na full cells, a high reversible capacity of 88, 89.8, and 50.3 mAh g(-1) can be sustained after 1600, 1000, and 600 cycles at room temperature, 55 degrees C and -40 degrees C, respectively. The pretreatment formed artificial hybrid interlayer proves to be an effective strategy to achieve wide-temperature-range SMBs.
