    摘要:

    在水熱合成過程中加入表面活性劑十六烷基三甲基溴化銨（CTAB），調(diào)節(jié)乙二醇的用量為50vol%，合成了鎂離子電池正極材料CuS-C50。結(jié)果表明：CuS-C50具有完整的納米花狀結(jié)構(gòu)，在氯化鋁-季戊四醇四甲醚/四氫呋喃（APC/THF）電解液中，當(dāng)電流密度為50 mA/g時(shí)，其比容量高達(dá)331.19 mAh/g；當(dāng)電流密度為200 mA/g時(shí)，其比容量在50次循環(huán)后仍保持136.92 mAh/g。形貌表征結(jié)果表明，完整的納米花狀結(jié)構(gòu)可以提供更多的活性位點(diǎn)，減少M(fèi)g2+的移動(dòng)障礙，最終提高鎂離子電池CuS正極材料的充放電性能。

    Abstract:

    CuS-C50, the cathode materials for magnesium ion batteries, was synthesized by adding the surfactant cetyltrimethyl ammonium bromide (CTAB) and adjusting the percentage of ethylene glycol to 50vol% in hydrothermal synthesis process. Results show that CuS-C50 has the complete nanoflower structure. In aluminum chloride-pentamethylcydopentodiene/tetrahydrofuran (APC/THF) electrolyte, the CuS-C50 exhibits a high specific capacity of 331.19 mAh/g when the current density is 50 mA/g and still keeps a specific capacity of 136.92 mAh/g over 50 cycles when the current density is 200 mA/g. Results of morphology characterizations indicate that the complete nanoflower structure can provide more active sites and reduce the barriers for Mg2+ movement, eventually improving the charge and discharge performance of the CuS cathode materials for magnesium ion batteries.
