摘要：The precursor of LiNi0.5Mn1.5O4 cathode material with high density was synthesized by two-dryness co-precipitation method. The feasible parameters were found out by studying the manner of dryness. The highest density (1.74 g/cm(3)) of precursor can be achieved under two-step dryness. Results of chemical and XPS analysis, XRD and SEM show the ratio of Ni to Mn is 1:3 and the precursor shows slice structure with well crystallization. Test of charge/discharge shows LiNi0.5Mn1.5O4 from such precursor exhibits a good electrochemical activity
