摘要
Bi2S3 的高理论容量使其成为锂离子电池(LIB)的理想负极材料;然而,容量快速衰减和长期稳定性差是其广泛应用的主要障碍。在这项工作中,利用氧自掺杂策略合成了 O-Bi2S3@C,大大增加了锂离子存储的活性位点数量。同时,硫空位的形成提高了 Bi2S3@C 的导电性和离子传输效率,增强了其长期稳定性,并加速了其电化学动力学过程。O-BSC-S1:3 阳极在 0.2 A g-1 的条件下显示出 673.1 mAh g-1 的可逆容量。在 3 A g-1 的高密度锂电池中,经过 1100 次循环后,它仍能保持 596.3 mAh g-1 的长期容量。此外,已安装的 O-Bi2S3@C//LiCoO2 全电池在 0.2 A g-1 的条件下具有优异的可逆容量和显著的循环能力(200 次循环后为 325.2 mAh g-1)。氧自掺杂和硫空位相结合的策略有效地提高了 Bi2S3 的可逆容量和循环寿命,为设计用于 LIB 的高性能过渡金属硫化物阳极提供了一种方法。
High theoretical capacity of Bi2S3 propels it toward an ideal anode material for lithium-ion batteries (LIBs); however, rapid capacity attenuation and poor long-term stability are major barriers to widespread application. In this work, an oxygen self-doping strategy was utilized to synthesize O-Bi2S3@C, significantly increasing the amount of active sites for lithium-ion storage. Meanwhile, sulfur vacancies were formed to improve the electrical conductivity and ionic transport efficiency, enhance the long-term stability, and accelerate the electrochemical kinetics of Bi2S3@C. O-BSC-S1:3 anode exhibits a reversible capacity of 673.1 mAh g-1 at 0.2 A g-1. It retains a long-term capacity of 596.3 mAh g-1 over 1100 cycles at a high density of 3 A g-1 in LIBs. Moreover, the installed O-Bi2S3@C//LiCoO2 full battery offers exceptional reversible capacity and remarkable cyclability (325.2 mAh g-1 after 200 cycles) at 0.2 A g-1. The combined strategy of oxygen self-doping and sulfur vacancy effectively enhances the reversible capacity and cycling life of Bi2S3, providing an approach for the design of high-performance transition metal sulfide anodes for LIBs.
