Abstract

The electrochemical behavior of Na-ion and Li-ion full cells was investigated, using hard carbon as the anode material, and NaNi_0.5Mn_0.5O₂ and LiNi_0.5Mn_0.5O₂ as the cathodes. A detailed description of the structure, phase transition, electrochemical behavior and kinetics of the NaNi_0.5Mn_0.5O₂ cathodes is presented, including interesting comparison with their lithium analogue. The critical effect of the hard carbon anodes pretreatment in the total capacity and stability of full cells is clearly demonstrated. Using impedance spectroscopy in three electrodes cells, we show that the full cell impedance is dominated by the contribution of the cathode side. We discuss possible reasons for capacity fading of these systems, its connection to the cathode structure and relevant surface phenomena.
