Abstract

The invention relates to preparation equipment of lithium manganate, in particular to a preparation device of a lithium manganate battery positive electrode material. The preparation device comprisesa calcination chamber, wherein the calcination chamber is separated into a left space and a right space by a heat conduction plate; one space is a heat supply chamber; the other space is an accommodating chamber for containing lithium manganate gel; the upper side of the accommodating chamber is provided with a container capable of containing liquid; the heat supply chamber transfers heat to the accommodating chamber so that the lithium manganate gel is dried and calcined; the container is heated through afterheat after the drying and the calcination in the calcination chamber. The gel containing, drying and calcination can be realized through one calcination chamber; the design is ingenious; the structure is simple; the cost can be reduced; meanwhile, the container arranged at the upper side of the accommodating chamber is heated by using the afterheat; the whole process flow process from gel preparation to calcination is realized; the energy sources can be saved; the work efficiencyis greatly improved.

Description

technical field

[0001] The invention relates to a preparation device for lithium manganate, in particular to a preparation device for a cathode material of a lithium manganate battery. Background technique

[0002] Lithium manganese oxide has become the first choice for power lithium-ion battery cathode materials due to its advantages of rich manganese resources, low cost, good safety, no environmental pollution, and easy preparation. However, the main reason hindering the formation of power battery-type lithium manganate industrialization capacity is Its performance is not stable enough, that is, its capacity decays quickly during the charge-discharge cycle, especially at high temperatures. At present, the main methods of lithium manganate can be divided into solid-phase method and liquid-phase method. Liquid-phase methods such as sol-gel methods are widely used in the preparation of nano-ceramic powders, films and fiber coatings. Because this method can realize uniform m...

Embodiment Construction

[0013] Combine below figure 1 The present invention is described in detail, and the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not as a limitation to the present invention.

[0014] The preparation device for the positive electrode material of lithium manganate battery includes a roasting chamber 1, which is divided into two spaces on the left and right by a heat conduction plate 2, one of which is a heating chamber 11, and the other space is a chamber for holding lithium manganate gel. Accommodating chamber 12, the heat supply chamber transfers heat to the accommodating chamber to dry and roast the lithium manganate gel. It can be seen that the present invention utilizes a roasting chamber to realize the holding, drying and roasting of the lithium manganate gel. The structure is simple and the cost is low. At the same time, the container 4 is heated through the preheating of the storage chamber, which not on...
