| titleOfInvention | Method for preparing lithium iron phosphate by sintering lithium iron phosphate precursor and microwave sintering equipment |
| abstract | The invention discloses a method and equipment for preparing lithium iron phosphate from a lithium iron phosphate precursor. The method comprises the three process steps of pretreatment of the lithium iron phosphate precursor material, pre-sintering and sintering; and in a non-oxidizing environment, the precursor material is heated by a certain number of microwave heaters, and the three process steps are finished by controlling treatment temperature and treatment time to finally prepare the lithium iron phosphate product. The equipment comprises a material inlet, a material feeding ventilation chamber, a pretreatment unit furnace, a pre-sintering unit furnace, a sintering unit furnace, a material discharging ventilation chamber, a cooling material discharging mechanism, a material outlet, a vacuumizing device, a protective gas input device and an equipment control circuit. In the method, the pretreatment and pre-sintering process steps are added to optimize a lithium iron phosphate microwave sintering process and solve keys problems on product quality control. The equipment provided by the invention realizes continuous microwave sintering by a plurality of unit furnaces so as to improve the sintering efficiency and realize large-scale industrial production. |
