摘要
通过一步水热法成功制得氧化锌(ZnO)/石墨烯(GN)纳米复合材料。测试表明,ZnO/GN复合材料中纤锌矿结构的ZnO纳米棒直径100~200nm,均匀担载在GN网状结构中。ZnO/GN复合材料展现出了优异的电化学性能:在0.1A/g电流密度下的可逆放电比容量达1171mAh/g;0.4A/g充放电循环测试100次后,放电容量仍然维持在305mAh/g。
ZnO/graphene nano-composite was synthesized by a simple hydrothermal method. The obtained ZnO nanorods had a size of 100 ~ 200 nm in diameter,which were distributed uniformly in the networks of graphene. As the cathode material,ZnO/graphene showed good electrochemical performance. The discharge capacity was as high as 1171 mAh/g at 0. 1A/g. After 100 cycles at 0. 4A/g,the discharge capacity was still 305 mAh/g.
