摘要	The reuse of waste materials helps to alleviate the pressure on sustainable economic development caused by the rapid consumption of natural resources. In this paper, a new process for the recovery of Li and Mn from spent LiMn2O4 cathode materials was studied. LiMn2O4 was mixed with NaHSO4 center dot H2O according to a certain mass ratio and roasted, and then the roasted products were leached with deionized water. The chemical changes during roasting were studied by thermogravimetric analysis, differential scanning calorimetry, X-ray diffraction, X-ray photoelectron spectroscopy, and scanning electron microscopy. After roasting, Li exists in the form of LiNaSO4, while the form of Mn is affected by the content of NNaHSO4 center dot H2O in the mixture. Within the corresponding temperature range, the chemical reaction between LiMn2O4 and NaHSO4 center dot H2O can proceed spontaneously. During the reaction, the following reactions will occur in the II and IV stages: NaHSO4 center dot H2O -> NaHSO4 + H2O(g), Na2S2O7 -> Na2SO4 + SO3 (g) and reaction of different metal oxides with SO3, and their average activation energies are 153.07 kJ/mol and 533.81 kJ/mol, respectively, and the restrictive link is three-dimensional diffusion. The roasted products were leached with deionized water, the extraction rate of Li and Mn elements increases with the decrease of mixing mass ratio, when the mass ratio of LiMn2O4 to NaHSO4 center dot H2O is 1:1.07, the roasting temperature is 873 K, the roasting time is 0.5 h, under the condition of water leaching temperature of 333 K, the extraction rates of Li and Mn were 96.6% and 9.7%, respectively.
