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
The invention belongs to lithium electricity powder body material sintering art, especially relates to a kind of anode material for lithium-ion batteries dress alms bowl blocking devices.
Background technology
At present, the preparation of anode material for lithium-ion batteries is substantially all have cobalt, nickel, manganese, ferric phosphate oxide etc. and lithium salt, then through oversintering, process.Through mixed material in sintering process, require material and air or the sufficient haptoreaction of other atmosphere, just can prepare the positive electrode that superior performance, product are stable, and at present for taking up the saggar that the instrument of mixed material is all generally mullite material, along with the increase of outage degree in saggar, the material of saggar inside can not contact with atmosphere more fully.There is following shortcoming in technique of the prior art: 1, saggar materials inside fully can not contact with atmosphere, cause reaction not exclusively, and the impurity of volatile not easily discharged, form product structure defect; 2, through the material of high temperature sintering, can shrink, and hardness is very high, inconvenient subsequent operation.
Summary of the invention
The problem that the invention will solve is to provide a kind of anode material of lithium battery dress alms bowl block device, the contact area of saggar materials inside and atmosphere can be increased, make reaction more abundant, reduce product structure defect, solve that volume of material after sintering is large and hardness is high simultaneously, be not easy to the problem of subsequent operation.
For solving the problems of the technologies described above, the technical scheme that the invention adopts is: a kind of anode material of lithium battery dress alms bowl block device, comprises pressing plate and piecemeal plate; Described piecemeal plate is connected to the bottom of described pressing plate and vertical with described pressing plate; Described piecemeal plate is cell structure.
Further, the lattice of the cell structure of described piecemeal plate can be triangle, parallelogram, regular pentagon or regular hexagon.Because these shapes all can realize tight arrangement.
Further, the top of described pressing plate or side are provided with handle.Conveniently press and mention anode material of lithium battery dress alms bowl block device.
Further, described pressing plate and piecemeal plate are nonmetallic materials.Can avoid bringing metal impurities into, cause and the mortality of material is destroyed.
Further, the lattice of the cell structure most peripheral of described piecemeal plate are semi-enclosed.Namely cell structure is without outer rim, resistance when can reduce to press.
Further, described pressing plate is provided with multiple through hole.During convenient pressing, air is discharged from through hole, resistance when reducing to press.
Further, all there is a through hole each lattice corresponding position of the cell structure of described pressing plate and piecemeal plate.
Further, the lattice of the cell structure most peripheral of described piecemeal plate are semi-enclosed, and all there is a through hole other grid corresponding positions of described pressing plate and described piecemeal plate.Because the lattice of most peripheral are semi-enclosed, during pressing, air can be discharged from the side, does not need to establish through hole.
The advantage that the invention has and good effect are: by adopting technique scheme, and a kind of anode material of lithium battery dress alms bowl block device, comprises pressing plate and piecemeal plate; Described piecemeal plate is connected to the bottom of described pressing plate and vertical with described pressing plate; Described piecemeal plate is cell structure.The material installed in saggar can be divided into multiple fritter by the piecemeal plate of described block device, material can fully be contacted with atmosphere in high-temperature sintering process, make reaction more abundant, reduce product structure defect, be divided into multiple fritter volume little with material after sintering, and be convenient to follow-up process operation.

Detailed description of the invention
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the invention.
As depicted in figs. 1 and 2, a kind of anode material of lithium battery dress alms bowl block device, comprises pressing plate 1 and piecemeal plate 2; Described piecemeal plate 2 is connected to the bottom of described pressing plate 1 and vertical with described pressing plate 1; Described piecemeal plate 2 is cell structure.Each lattice of the cell structure of described piecemeal plate 2 are square, often horizontally-arranged five square lattice, every vertical setting of types five square lattice, also can be other parallelogram or triangle, regular pentagon and regular hexagon, certainly because these shapes all can realize tight arrangement; The top of described pressing plate 1 is provided with handle 3, conveniently exerts a force to anode material of lithium battery dress alms bowl block device and has pressed rear proposition anode material of lithium battery dress alms bowl block device.Certainly, also two handles 3 can be set in the side of pressing plate 1, same technique effect can be played.Described pressing plate 1 is provided with multiple through hole 4.Except most peripheral square especially, all there is a through hole 4 described pressing plate 1 and each square lattice corresponding position.Described pressing plate 1 and piecemeal plate 2 are Merlon material, can certainly be other nonmetallic materials, as Other Engineering plastics, glass, pottery, timber etc., avoid bringing metal impurities into, cause the mortality of material to destroy.When embody rule, the size of anode material of lithium battery dress alms bowl block device can design and produce according to the size of matching used saggar.
The specific works process of the present embodiment: first install mixed material in saggar, before sintering, hold the handle 3 above anode material of lithium battery dress alms bowl block device, anode material of lithium battery being filled alms bowl block device inserts in saggar, material in saggar can be cut into the material of multiple blockage by piecemeal plate 2, the material of blockage is in high-temperature sintering process, there is chemical reaction, and shrink, cut channel place is increasing, atmosphere is just more prone to contact with material, and sintering after material be divided into a lot of fritter after, be beneficial to very much the process of subsequent handling.In addition, pressing plate 1 leaves multiple through hole 4, when cutting material, air can be discharged smoothly from through hole 4, reduces the resistance of pressing downwards, is beneficial to operation.
Above an embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, the practical range for limiting the invention can not being considered to.All equalization changes done according to the invention application range with improve, within the patent covering scope that still all should belong to the invention.
