与插层型锂离子电池（LIB）相比，转换型锂硫（Li-S）电池因为其高理论能量密度（2600 Wh kg-1）而受到越来越多的关注。但是，多硫化物穿梭效应、缓慢的反应动力学和锂金属枝晶生长等问题阻碍了锂硫电池的进一步应用。硫正极的多步转化反应涉及电极/电解质之间一系列Li+的交换，这些反应也亟需克服脱溶剂和电荷载体扩散的能量势垒，这导致了缓慢的转化动力学以及多硫化物中间体的积累。

压电现象源于材料的非中心对称结构，这种结构依赖性严重限制了压电材料种类。理论上，基于表面修饰的对称性破缺可用于增强材料压电性能。例如，密度泛函理论（DFT）计算结果表明，中心对称的石墨烯可通过特定原子(F、H)的选择性吸附获得压电响应，但此类研究大多局限于理论模型，实验手段难以实现。2022年来，单原子在催化领域受到了广泛关注，研究者利用金属原子与载体的配位作用改变材料表面化学结构，获得催化性能提...
