A binary metal sulfide hybrid consisting of nanowire-assembled and polypyrrole-coated CoS/CuS spheres after nitrogen-doped carbon coating (CoS/CuS@NC) is developed as an anode, which displays a capacity exceeding 412.3 mA h g after 550 cycles under 1.0 A g. Recoverable rate-performance and good temperature tolerance under 50 °C and -10 °C are achievable; a full cell delivers 339.5 mA h g, indicating promising potential for applications in various conditions.
一种由纳米线组装且经聚吡咯包覆的CoS/CuS球体在进行氮掺杂碳包覆后形成的二元金属硫化物杂化物（CoS/CuS@NC）被开发用作阳极，该阳极在1.0 A g的电流密度下经过550次循环后显示出超过412.3 mA h g的容量。在50℃和-10℃下可实现可恢复的倍率性能和良好的温度耐受性；一个全电池的容量为339.5 mA h g，表明其在各种条件下的应用具有广阔前景。
