摘要:The present invention relates to a production apparatus for hydrothermal synthesis of lithium iron phosphate, which comprises first stirring devices, a preheating device, a second stirring device, and a drying device, wherein there are two first stirring devices, and the preheating device comprises a housing, a heating box, two feeding pumps, two first transfer assemblies, and several first heating tubes; the two first transfer assemblies each comprise an inlet pipe, an outlet pipe, and several transfer branch tubes. In the present application, the arrangement of multiple transfer branch tubes increases the heated area of the slurry, enhances the thermal conduction efficiency, and improves the heating effect. The equidistant arrangement of the transfer branch tubes ensures uniform heating of the slurry within the multiple transfer branch tubes, guaranteeing the heating effect. The arrangement of the preheating device can reduce the heating time of the slurry, thereby enhancing the heating effect.

摘要:A method is provided for the synthesis of a mesoporous lithium transition metal compound, the method comprising the steps of (i) reacting a lithium salt with one or more transition metal salts in the presence of a surfactant, the surfactant being present in an amount sufficient to form a liquid crystal phase in the reaction mixture (ii) heating the reaction mixture so as to form a sol-gel and (iii) removing the surfactant to leave a mesoporous product. The mesoporous product can be an oxide, a phosphate, a borate or a silicate and optionally, an additional phosphate, borate or silicate reagent can be added at step (i). The reaction mixture can comprise an optional chelating agent and preferably, the reaction conditions at steps (i) and (ii) are controlled so as to prevent destabilization of the liquid crystal phase. The invention is particularly suitable for producing mesoporous lithium cobalt oxide and lithium iron phosphate. The method can be used to synthesize mesoporous lithium cobalt oxide having a specific surface area in excess of 10 m 2 /g, preferably 15 m 2 /g or more.
