Synthesis and electrochemical characterization of LiNi0.5Mn1.5O4 by one-step precipitation method with ammonium carbonate as precipitating agent

Spinel LiNi0.5Mn1.5O4 materials are synthesized by one-step precipitation method. Ammonium carbonate is used as the precipitating agent to obtain a more precise feed ratio without recourse to traditional washing. After annealing at high temperature, the spherical particles become angular and show high levels of crystallinity. The synthesized samples are evaluated using powder X-ray diffraction, scanning electron microscopy, and electrochemical...
