| Abstract: | NaNi1/3Co1/3Mn1/3O2 material was synthesized by a facile method, and the suitable working voltages (3.75 V, 4 V) are investigated afterwards. The mechanisms of the capacity fading when charging to 4 V are studied. All these results will be possibly effective for the manufacture of the NaNi1/3Co1/3Mn1/3O2 material in large scale. |
