Abstract: The electrode–electrolyte interfaces play a critical role in influencing the cyclic stability, Coulombic efficiency, and safety of rechargeable batteries. Although there are many recent efforts for investigating the solid electrolyte interface formed on anodes, much less attention has been paid to examine the cathode–electrolyte interface (CEI) established on cathodes. Understanding of the chemistry, morphology, and structure of CEI layers is still illusive requiring further in‐depth characterization. The cryogenic electron microscopy is used to reveal a 1.1 nm thick CEI layer formed on a flower‐shaped, carbon‐coated Na 3 V 2 (PO 4 ) 3 /C (NVP/C) cathode in ether‐based electrolyte for Na‐ion batteries. The rationally designed NVP/C cathode delivers cyclic stability with a capacity retention of over 88% at 50 mA g −1 after 1600 cycles and an excellent high‐rate capability at up to 3200 mA g −1 . These findings may shed new light on the design of CEI layers to achieve high energy and power densities in rechargeable Na‐ion/metal batteries.

Abstract: Three‐dimensional host structures with superior sodiophilicity and low nucleation barriers can help combat the complex failure modes of Na metal anodes originating from accelerated dendrite formation, anodic corrosion, and electrolyte depletion. This work reports the fabrication of a unique super‐sodiophilic, defect‐rich and hierarchically porous skeletal carbon nanofiber (SCNF) host for SCNF@Na anodes using electrospinning of the low‐cost, renewable lignin biopolymer. The uniform nucleation and plating of Na effectuated by the hierarchically porous structure coupled with the defect‐induced formation of a resilient, F‐rich solid electrolyte interface (SEI) layer offers excellent protection to the metallic anode. The defect‐rich porous structure plays an important role in mediating dense Na nucleation, planar growth, and electrochemical stability according to the depth profiling experiments and density functional theory calculations. The SCNF@Na composite anode maintains high Coulombic efficiencies (CEs) and electrochemical reversibility in asymmetric and symmetric cells. The full cells prepared by interfacing the SCNF@Na anode with a Na 3 V 2 (PO 4 ) 2 F 3 cathode delivers exceptional capacity retention of 106 mAh g –1 for 350 cycles with an average CE of 99.2% at 1C, and 103 mAh g –1 after 200 cycles at 4C. Such rationally designed carbon hosts derived from biopolymers open a new avenue for safe and low‐cost metal batteries.
