Embodiment
[0015] Such as figure 1 , the process flow diagram adopted in the present invention, the packaging equipment once includes a mixer, a vibrating screen, an iron remover, and a packaging machine, and three and then connected to the main pipeline through the pipeline, so that there are multiple channels inside the packaging system. During the packaging process, the materials and gases inside the system form different pipe convection, that is, when the pressurized packaging bag is connected to the packaging machine, the packaging bag The gas in the system is upward, the material in the system is downward, and the material and gas in the system form countercurrent flow.
[0016] Clean the whole system, then put 1 ton of dried ternary precursor material into the mixer, set the mixing parameters, and turn on the mixer to mix for 30 minutes;
[0017] Set the parameters of the vibrating screen, iron remover and packaging machine according to the process requirements. After the mixing ...

The invention discloses a packaging method for a ternary precursor material. A mixing machine, a screening machine, an iron remover, and a packaging machine are used to sequentially mix, sieve, remove iron, and pack the ternary precursor material to complete the packaging. The mixing machine, screening machine, iron remover, and packaging machine are connected through pipelines, and the packaging bag is connected to the outlet of the packaging machine to complete the packaging of the ternary precursor material during packaging, and the packaging bag is under pressure. The application of the present invention connects the mixing machine, screening machine, iron remover, and packaging machine of the ternary precursor material packaging system through pipelines, and uses a pressurized packaging bag to connect to the outlet of the packaging machine to complete the ternary precursor material during packaging. The packaging can make the material and gas in the system form an opposite direction convection, which effectively prevents the leakage and waste of materials during the packaging process, and the direct product recovery rate is greater than 99.2%.
Description
technical field [0001] The invention relates to the technical field of lithium ion batteries, in particular to a packaging method for a ternary precursor material. Background technique [0002] At present, lithium-ion batteries occupy a large market share in the field of portable electronic devices by virtue of their advantages such as high specific capacity, long cycle life, low self-discharge rate, no memory effect, and environmental friendliness, and are recognized as the most promising electric battery. Vehicle power battery. Cathode materials are an important part of lithium-ion batteries. The current commercial cathode materials are mainly lithium iron phosphate, lithium manganese oxide, lithium cobalt oxide, and ternary materials. The characteristics of the elements have become a hot spot in the current research on the positive electrode materials of power batteries. It has important advantages such as better performance than lithium cobalt oxide, much lower cost tha...
