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。
The birnessite manganese oxide was precipitated on the stripped graphite oxide layer. Using a self-aligned graphite oxide coated with a single layer of manganese oxide, a novel graphite oxide-manganese oxide Composites. The electrochemical properties of the obtained material as a positive electrode material for lithium ion secondary batteries were measured. The results show that the nanocomposite has a higher charge-discharge cycle than birnessite manganese oxide.
