摘要
本文以聚苯乙烯球为模板,杨梅单宁/Cu2+混合物为前驱体,制备了三维有序多孔碳内嵌纳米Cu_2O-CuO(3D Cu_2O-CuO@C)锂离子电池负极材料。采用多种技术手段研究了3D Cu_2O-CuO@C结构形貌及其电化学性能。3D Cu_2O-CuO@C在电流密度为1.0 A·g-1的循环性能测试中,500次循环后其放电比容量为635.8 m A·h·g~(-1),表现出了高循环稳定性。在电流密度为8.0 A·g-1的大电流条件下,其放电比容量仍维持在173.4 m A·h·g~(-1),表现出了优异的高倍率性能。
Three dimensional ordered porous carbon encapsulated nanoscaled Cu_2O-CuO(3 D Cu_2O-CuO@C) was prepared as the anode materials of Li-ion battery by using polystyrene sphere as template and the mixture of bayberry tannin/Cu2+as precursor. The morphology and electrochemical properties of 3 D Cu_2O-CuO@C were fully investigated by various techniques. The 3 D Cu_2O-CuO@C electrode delivered the specific capacity high up to 635.8 mA·h·g~(-1) after500 discharge/charge cycles at the current density of 1.0 A·g-1. At the high current density of 8.0 A·g-1, the specific capacity still reached 173.4 mA·h·g~(-1), exhibiting appreciable high-rate capability.
