Embodiment Construction

[0017] Specific embodiments of the invention will be described in detail below in conjunction with the accompanying drawings.

[0018] like figure 1 and figure 2 As shown, a lithium battery cathode material bowl divider, including a pressing plate 1 and a dividing plate 2; the dividing plate 2 is connected to the bottom of the pressing plate 1 and is perpendicular to the pressing plate 1; the dividing plate The block plate 2 is a grid structure. Each grid of the grid structure of the block plate 2 is a square, with five square grids in each row and five square grids in each vertical row. Of course, it can also be other parallelograms or triangles, regular pentagons and regular hexagons. because these shapes can be closely arranged; the top of the pressure plate 1 is provided with a handle 3, which is convenient for applying force to the blocker for the anode material of the lithium battery and lifting the anode material for the anode of the lithium battery after the pressin...

Abstract

The invention provides a partitioning device for saggar loading of lithium battery positive electrode materials. The partitioning device comprises a pressing plate and partitioning plates. The partitioning plates are connected to the bottom of the pressing plate and are perpendicular to the pressing plate. The partitioning plates are of a grid structure. The materials contained in a saggar can be divided into a plurality of small blocks through the partitioning plates of the partitioning device for saggar loading of the lithium battery positive electrode materials, and therefore the materials can make full contact with an atmosphere in the high-temperature sintering process, a reaction is made more sufficient, and product structure defects are reduced; meanwhile, the sintered materials are divided into the multiple small blocks which are small in size, so that follow-up processing operation is facilitated.

Description

technical field [0001] The invention belongs to the field of sintering of lithium battery powder materials, and in particular relates to a blocking device for anode material of lithium ion battery. Background technique [0002] At present, the preparation of positive electrode materials for lithium-ion batteries is basically made by mixing and grinding cobalt, nickel, manganese, iron phosphate oxides, etc., and lithium salts, and then sintering and processing. During the sintering process of the mixed material, it is required to fully contact the material with air or other atmospheres in order to prepare a positive electrode material with superior performance and stable products. Currently, the tools used to hold the mixed material are generally mullite. For the saggar made of different materials, as the height of the inner space of the sagger increases, the materials inside the sagger cannot fully contact with the atmosphere. The process in the prior art has the following ...
