| 摘要: 为了开发电化学性能优异的新型金属有机骨架基衍生材料，以对苯二甲酸、三氯化铬和九水合硝酸铁作为原料，通过微波法合成了双金属有机骨架材料（Fe-Cr-MOF）。在氮气保护下，对Fe-Cr-MOF进行高温硒化得到纳米颗粒状Fe-CrSe/C复合材料，用作锂离子电池负极。结果表明，在100 mA·g-1的电流密度下，Fe-CrSe/C电极的首圈可逆比容量达到958.4 mAh·g-1，循环150圈后比容量还能维持891.6 mAh·g-1。 | |

| Abstract: To develop novel metal-organic framework-based derivatives with excellent electrochemical properties, a bimetal-organic framework (Fe-Cr-MOF) was synthesized by microwave method using terephthalic acid, and chromium trichloride, and ferric nitrate nonahydrate as raw materials. Under nitrogen protection, Fe-Cr-MOF was selenized at high temperatures to obtain nanoparticulate Fe-CrSe/C composites, which were used as anode materials for lithium-ion batteries. The results showed that the reversible specific capacity of the Fe-CrSe/C electrode reached 958.4 mAh·g-1 in the first cycle, and the specific capacity can maintain 891.6 mAh·g-1 after 150 cycles at the current density of 100 mA·g-1. | |
