高温热解法制备Ni掺杂纳米MnO的性能
Performance of Ni doped MnO nanoparticles synthesized by high temperature pyrolysis method
摘要
Abstract
5％Ni doped nano MnO (5％ Ni-MnO) was synthesized by high temperature pyrolysis method from nickel acetate tetrahydrate and manganese acetate tetrahydrate.The crystal form and particle morphology of the samples were analyzed by XRD and SEM.5％ Ni-MnO samples were evenly distributed between 50-100 nm particles.The galvanostatic charge and discharge method test resuhs showed that 5％ Ni-MnO had a high reversible capacity of 845.4 mAh/g obtained at 0.2 C with the voltage of 0-3.0 V,the initial discharge coulomb efficiency was 77.1％.At 5.0 C rate,the capacity was still reach up to 407.4 mAh/g.关键词
