摘要
将水钠锰矿型锰氧化合物沉淀于剥离状态的氧化石墨层上,利用被锰氧化合物单层所 包裹的氧化石墨的自配列,合成了一种新型氧化石墨-锰氧化合物隔层排列的纳米复合材料。 测量了将得到的材料作为锂离子二次电池正极材料时的电化学性质,结果表明这种纳米复合 材料具有比水钠锰矿型锰氧化合物更高的充放电再循环性。
Birnessite manganese oxide layers were precipitated in-situ on the surface of exfoliated graphite oxide (GO) layers. Using the self-assembly of the GO layers encapsulated with birnessite monolayers, a novel interstratified nanocomposite of GO-birnessite was synthesized. The electrochemistry properties of the material as a cathode for lithium secondary battery were investigated. The result indicated that the nanocomposite had improved charge-discharge recycleability better than birnessite manganese oxide.
