摘要
以MnCO_(3)为锰源、酚醛树脂为碳源,不同锰碳比制备氧化锰/碳复合材料,研究了不同锰碳比对氧化锰/碳产物结构、形貌以及电化学性能的影响。通过X射线衍射(XRD)、扫描电镜(SEM)以及LAND电化学测试等手段对试样进行表征。结果表明:锰氧化物∶酚醛树脂=2∶1制备样品的粒度均匀,电化学性能优异,500次可逆容量为590.9mAh/g。
manganese oxide/carbon(MnO/C)composites were prepared with MnCO_(3)as manganese source and phenolic resin as carbon source.The effects of different manganese carbon ratio on the structure,morphology and electrochemical properties of MnO/C products were studied.The results of X-ray diffraction(XRD),electron microscope(SEM)and Land electrochemical test shown that the prepared samples with MnO∶phenolic resin=2∶1 had the uniform morphology and excellent electrochemical performance,and the reversible capacity was 590.9 mAh/g after 500 cycle times.
