performance of the materials were discussed, and it was found that 600 °C is an optimal calcination temperature to prepare an anhydrous hexagonal layer P2 structure compound. In this work, cathode materials... (x = 0.4, 0.5, 0.6, 0.7, 1.0; d = 0-0.3) cathode materials with different Na contents were prepared by adjusting the initial stoichiometric ratio of Na to Mn. All these samples are highly porous......
