摘　　要：Lithium-ion batteries that integrate electrochemical performance and safety considerations offer advantages to curb the reliance on fossil fuels while minimizing the potential environmental risks.Transition metal disulfides and metal oxides with high specific capacity are promising candidates as anodes for lithium storage.However,neither the layered structure of MoS_(2) nor the powder form of In_(2)O_(3) is ideal for battery prolonged applications.Herein,we demonstrated a low-toxicity anode designed with hollow fibers to regulate the MoS_(2) contact surface,significantly reducing biotoxicity and enhancing Lit diffusion.Density functional theory(DFT)calculations revealed that the interactions among MoS_(2),In_(2)O_(3),and the hollow structure lowered the Li-ion migration energy barrier hence fastening the diffusion.Moreover,the MoS_(2)-containing fiber showed significantly decreased toxicity in zebrafish embryos compared to MoS_(2) alone,demonstrating a proof-of-principle of integrating functional nanomaterials into flexible fiber structures to improve both electrochemical performance and safety.
