Pyrite FeS2 as a high‐capacity electrode material for lithium‐ion batteries (LIBs) is hindered by its unstable cycling performance owing to the large volume change and irreversible phase segregation from coarsening of Fe. Here, the beneficial microstructure evolution in MoS2‐modified FeS2 is unraveled during the cycling process; the microstructure evolution is responsible for its significantly boosted lithium storage performance, making it suitable for use as an anode for LIBs. Specifically, the FeS2/MoS2 displays a long cycle life with a capacity retention of 116 % after 600 cycles at 0.5 A g−1, which is the best among the reported FeS2‐based materials so far. A series of electrochemical tests and structural characterizations substantially revealed that the introduced MoS2 in FeS2 experiences an irreversible electrochemical reaction and thus the in situ formed metallic Mo could act as the conductive buffer layer to accelerate the dynamics of Li+ diffusion and electron transport. More importantly, it can guarantee the highly reversible conversion in lithiated FeS2 by preventing Fe coarsening. This work provides a fundamental understanding and an effective strategy towards the microstructure evolution for boosting lithium storage performances for other metal sulfide‐based materials.

“…The inspiration by biological materials with complex, optimized, and hierarchical microstructures has been one of the most promising subjects in artificial material engineering. Generally, the bio-inspired material synthesis strategy is based on the self-assembly of specific guest species to obtain inorganic analogues of the biological materials [26][27][28][29]. Natural biological materials used as templates for the material synthesis are low cost, abundant, commercially viable, and environmentally benign [30].…”

HIGHLIGHTS • A viable bio-derived material engineering strategy is developed based on the use of skin collagen fibers for the crafting of metalnitride-carbon nanofiber composites. • N-doped carbon nanofiber bundles embedded with Fe 2 N nanoparticles are fabricated using a structural replication process. • The composite with a hierarchically ordered, compact, and multicore-shell heterostructure exhibits increased lithium-and potassiumion storage performances. ABSTRACT Despite the significant progress in the fabrication of advanced electrode materials, complex control strategies and tedious processing are often involved for most targeted materials to tailor their compositions, morphologies, and chemistries. Inspired by the unique geometric structures of natural biomacromolecules together with their high affinities for metal species, we propose the use of skin collagen fibers for the template crafting of a novel multicore-shell Fe 2 N-carbon framework anode configuration, composed of hierarchical N-doped carbon nanofiber bundles firmly embedded with Fe 2 N nanoparticles (Fe 2 N@N-CFBs). In the resultant heterostructure, the Fe 2 N nanoparticles firmly confined inside the carbon shells are spatially isolated but electronically well connected by the long-range carbon nanofiber framework. This not only provides direct and continuous conductive pathways to facilitate electron/ion transport, but also helps cushion the volume expansion of the encapsulated Fe 2 N to preserve the electrode microstructure. Considering its unique structural characteristics, Fe 2 N@N-CFBs as an advanced anode material exhibits remarkable electrochemical performances for lithium-and potassium-ion batteries. Moreover, this bio-derived structural strategy can pave the way for novel low-cost and high-efficiency syntheses of metal-nitride/carbon nanofiber heterostructures for potential applications in energy-related fields and beyond.
