自支撑多孔碳/硒复合柔性电极的制备及其电化学性能
CHINESE JOURNAL OF INORGANIC CHEMISTRY(2021)
Abstract
以二氧化硅(SiO2)为模板,结合静电纺丝与溶胶-凝胶法制备了多孔碳纳米纤维膜(PCNFS),再通过熔融扩散法负载硒,制备了一种柔性的碳/硒复合电极(Se@PCNFS).结合X射线衍射(XRD)、扫描电子显微镜(SEM)和透射电子显微镜(TEM)对材料的微观结构和形貌进行表征,结果显示多孔碳纤维直径约300 nm,硒均匀地嵌入碳纤维膜的孔洞中.电化学测试结果表明,1Se@PCNFS电极在锂硒电池中表现出优异的循环性能和倍率性能.在0.5C倍率下,初始放电比容量达到569 mAh·g-1,循环500次后比容量为340 mAh· g-1;在2C倍率时,比容量为403 mAh·g-1.
