Aqueous zinc-ion batteries (AZIBs) have significant potential as a large-scale energy storage device due to their low cost and high safety. However, the formation of zinc dendrites during repeated plating stripping complicated side reactions has seriously hindered development AZIBs. Herein, N, P dual-doped biomass carbon was constructed by simple hydrothermal pyrolysis strategy. In this case, N heteroatoms increased defects made it easier form uniform stable interface with metal. On other hand, interfacial interactions between Zn2+ surface were enhanced introduction zincophilic groups, which lowered barriers required for nucleation, resulting in deposition. Therefore, symmetric assembled Zn anodes based on exhibited outstanding cycling stability (2000 h) relatively small voltage hysteresis (45 mV) at current density 1 mA cm–2 an area capacity 0.15 mAh cm–2. Besides, VO2 cathode compose full battery, NPBC@Zn//VO2 battery 132.2 g–1 after 1500 cycles 5 A g–1, 76.8% retention. It is much higher than 27.7% Zn//VO2 battery. This work demonstrates novel two-element-doped carbon/Zn anode modification strategy achieve dendrite-free

Abstract Renewable and low-cost biomass is an ideal sustainable alternative to petroleum-based resources, but producing biomass-based carbon electrode with high performances remains a challenge. Herein, we propose facile self-assembly strategy fabricate biomass-derived N, S co-doping from lignosulfonate without any activation or template process. Taking advantage of the coordination between Fe ions lignosulfonate, resultant exhibits spherical structure abundant graphitized nanosheets, leading specific surface area rational pore structure, which are beneficial electron/ion transport storage. The contents doping N (8.47 wt%) (2.56 significantly boost electrochemical performances. As supercapacitor electrode, material displays capacitance 390 F g −1 , excellent cycling stability energy density 14.7 W h kg at power 450 . This study provides potential for synthesizing cost-effective heteroatom-doped materials functional groups heteroatom sources, such as chitosan, collagen, gelatin. Graphical
