As one of the most important elements in the halogen family, bromine has a theoretical specific capacity of 335 mAh g⁻¹, which makes it a very suitable active material for rechargeable batteries. In this study, we use the superb Br^- ion storage of MoS₂ nano-flowers, which achieve high specific capacity (1 5 1 $\mathit{mAh}{g}_{\mathit{Mo}{S}_2}^{-1}$) and excellent stability (more than 5000 cycles). Through a series of characterization analyses, it is proved bromine ions are intercalate in MoS₂ during the charging process. During discharge, Br^- deintercalates from MoS₂ and moves to the anode. This reversible and stable chemical action provides feasibility for the intercalation/deintercalation of bromine-based batteries. There is no doubt that this research will provide researchers with new strategies for bromine-based batteries.

作为卤素族中最重要的元素之一，溴的理论比容量为 335 mAh g ^-1，这使其成为非常适合可充电电池的活性材料。在这项研究中，我们使用了MoS ₂纳米花卓越的 Br ^-离子存储能力，实现了高比容量 (1 5 1   $\mathit{毫安时}{G}_{\mathit{莫}{秒}_2}^{——1}$) 和出色的稳定性（超过 5000 次循环）。通过一系列表征分析，证明在充电过程中溴离子嵌入MoS ₂中。在放电期间，Br ^-从MoS ₂脱嵌并移动到阳极。这种可逆且稳定的化学作用为溴基电池的嵌入/脱嵌提供了可行性。毫无疑问，这项研究将为研究人员提供溴基电池的新策略。
