Abstract A key challenge for sodium‐ion batteries (SIBs) lies in identifying suitable host materials capable of accommodating large Na + ions while addressing sluggish chemical kinetics. The unique interfacial effects heterogeneous structures have emerged as a critical factor accelerating charge transfer and enhancing reaction Herein, MoSe 2 /Bi Se 3 composites integrated with N‐doped carbon nanosheets are synthesized, which spontaneously self‐assemble into flower‐like microspheres (MoSe @N‐C). Electrochemical measurements density functional theory (DFT) calculations underscore the significant improvement kinetics enabled by structural advantages composite. Remarkably, nanosheet morphology provides more storage sites, uniformly distributed heterostructure can optimize carrier concentration alter electric field distribution, thereby facilitating enabling additional sodium ion storage. When employed an anode material SIBs, @N‐C exhibits exceptional performance, delivering reversible capacity 521.4 mAh g −1 at 1 800 cycles 407.9 10 over 1400 cycles. Notably, be fully restored to its initial level after cycling high current densities. This study, combining experimental theoretical insights, novel perspective on interface engineering advance practical application SIBs.

A key research focus at present is the exploration and innovation of electrode materials suitable for energy storage conversion. Molybdenum-based sulfides/selenides (primarily MoS2 MoSe2) have garnered attention in recent years due to their intrinsic two-dimensional structures, which are conducive ion/electron transfer or insertion/extraction, making them promising candidates electrocatalytic hydrogen production sodium-ion battery applications. However, inherently poor electronic structures led most efforts concentrate on modifications aimed enhancing performance evolution reactions (HERs) batteries (SIBs). Owing remarkable chemical inertness, expansive specific surface areas, tunable pore architectures, carbon-based significant research. The utilization biomass as a renewable environmentally sustainable precursor offers considerable benefits, including abundant availability, ecological compatibility, cost-effectiveness. Consequently, scholarly endeavors concentrated intensively synthesis valuable carbon derived from sources.
