We will describe a completed study on sodium-ion batteries. With the aim to offer a comprehensive view, we compared all the Na-ion systems studied herein to similar Li-ion systems. Na-ion and Li-ion full cells were investigated, using hard carbon as the anode material, NaNi0.5Mn0.5O2 and LiNi0.5Mn0.5O2 as the cathodes.A comprehensive description and discussion of the possible use of hard carbons as anode is presented. We explored storage mechanisms, cycling, stability, surface chemistry, and impedance behavior. We examined the choice of the binders, solvent and additives on the electrodes' performance. The critical effect of the hard carbon anodes pretreatment on the total capacity and stability of full cells will be discussed.
