Preparation and characterization of novel structure Co–B hydrogen storage alloy

The Co–B alloy was prepared by the chemical reduction method and the annealing method. The structural and morphological characterizations were performed using TEM and XRD. The Electrochemical Measurements were performed using LAND battery test instrument. After annealing treatment,the initial Co–B alloy decomposes to crystalline Co and B with a kind of coating sphere structure. The excellent electrochemical hydrogen storage properties are also obtained.
