电池电极材料方面的摘要
|
|||
| Carbon micro-particles (CMPs) possessing smooth surface and sphere shape, which have wide size distribution from 0.5 to 5 μm were prepared through a facile hydrothermal method using β-cyclodextrin as carbon source. Galvanostatic charge-discharge method was used to investigate the electrochemical performance of CMPs. The results showed that CMP anode exhibited an initial discharge capacity of 571 mAh g1 and a reversible capacity above 345 mAh g1 after 50 cycles. The good performance for the CMPs can be attributed to the smooth surface of the carbon spheres, which is advantageous in the formation of good and efficient passivation layers. This electrode material has promising applications in lithium ion batteries. |

| 碳micro-particles(CMPs)具有表面光滑、球体状,已被广泛粒径分布在0.5 ~ 5μm准备通过使用水热合成法奇妙β-cyclodextrin如碳源。通电快速锈蚀模拟充放电的方法被用来研究CMPs的电化学性能。结果表明,CMP阳极表现出初始排放能力?1号共571名从可逆能力超过345号1日之后?从50周期。良好的表现为CMPs被归咎于该表面光滑的碳球,这有利于形成优秀且有效率的钝化层。这个电极材料中有着很好的应用前景锂离子电池 |
