Abstract: 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 MoS2 nor the powder form of In2O3 is ideal for battery prolonged applications. Herein, we demonstrated a low-toxicity anode designed with hollow fibers to regulate the MoS2 contact surface, significantly reducing biotoxicity and enhancing Li+ diffusion. Density functional theory (DFT) calculations revealed that the interactions among MoS2, In2O3, and the hollow structure lowered the Li-ion migration energy barrier hence fastening the diffusion. Moreover, the MoS2-containing fiber showed significantly decreased toxicity in zebrafish embryos compared to MoS2 alone, demonstrating a proof-of-principle of integrating functional nanomaterials into flexible fiber structures to improve both electrochemical performance and safety.
