A core-shell structured selenium@carbon composite material was obtained by a facile one-step microwave synthesis method. The uniform carbon shells coated on selenium spheres greatly minimized the shuttle effect of Li-Se cells. The morphology analysis of the cathodes after different cycles revealed that the Se cores were perfectly confined inside the unbroken C shells all through the 100 cycles.
通过简便的一步微波合成法制备了一种核壳结构的硒@碳复合材料。包覆在硒球上的均匀碳壳极大地降低了锂硒电池的穿梭效应。对不同循环次数后的阴极进行形貌分析表明,在整个100次循环中,硒核完美地限制在完整的碳壳内部。
