Abstract
The utility model discloses a special saggar for a lithium battery cathode material, which comprises a saggar (1), wherein the saggar (1) is provided with a top cover (2) which is matched with the shape of the saggar, the side wall of the saggar (1) is provided with a through hole (3), and the upper edge of the through hole (3) stays on the same plane with the lower edge of the top cover (2). The special saggar has good atmosphere fluidity when being sintered in a push plate furnace for producing the lithium ion battery cathode material, so the homogeneity of the cathode material performance can be improved, continuous production of the push plate furnace can be realized, and the production efficiency can be improved; and the sintered cathode material has high quality and good performance, the special saggar also has characteristics of simple structure and long service life, and the special saggar is suitable for being popularized and used.
Description
Technical field
The utility model relates to a kind of saggar, the special-purpose saggar of specifically a kind of anode material of lithium battery.
Background technology
As everyone knows, lithium ion battery is the rechargeable battery of at present tool advantage performance.Along with the continuous popularization of lithium ion battery applications, the demand of anode material for lithium-ion batteries is not only increased.The preparation positive electrode that lithium ion battery adopted mainly is LiCoO at present

4And doping or modifier, and the capital equipment of producing them is pusher furnace (or being called sintering furnace, kiln), in pusher furnace, needs usually to adopt special-purpose saggar to load positive electrode, then saggar is put into pusher furnace material is carried out sintering.Existing saggar is generally the square saggar of sealing, and after positive electrode was put into saggar, saggar sealed when sintering, makes that the atmosphere in the pusher furnace can not circulate with the atmosphere in the saggar, and the product quality that causes sintering to come out is not high or performance is inhomogeneous.
Summary of the invention
The purpose of the utility model is the defective to prior art, provides a kind of anode material of lithium battery simple in structure, that product quality is high special-purpose saggar.
The purpose of the utility model solves through following technical scheme:
The special-purpose saggar of a kind of anode material of lithium battery comprises saggar, and saggar is provided with the top cover that matches with its shape, and the sidewall of said saggar is provided with through hole.
The upper edge of said through hole and the lower edge of top cover are positioned on the same horizontal plane.
The quantity of said through hole is 1-4.
Described through hole is rectangle.
The sidewall length ratio of the length of said through hole and saggar is 0.15-0.50.
The height of said through hole is 1-2cm.
The utility model is compared prior art has following advantage:
The saggar of the utility model atmosphere good fluidity during sintering in producing the pusher furnace of anode material for lithium-ion batteries has improved the uniformity of positive electrode performance, and has helped the serialization production of pusher furnace, enhances productivity.
Simple in structure, the long service life of the utility model, the positive electrode quality that sintering comes out is high, performance is good, suitable promoting the use of.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
Wherein: 1-saggar; 2-top cover; 3-through hole.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 1: the special-purpose saggar of a kind of anode material of lithium battery; Comprise saggar 1, above saggar 1, be provided with the top cover 2 that matches with its shape, on the sidewall of saggar 1, be provided with 1-4 through hole 3 in addition; A through hole 3 generally only is set on each sidewall of saggar 1; The lower edge of the upper edge of through hole 3 and top cover 2 is positioned on the same horizontal plane, and regular shape such as that the shape of through hole 3 can be is square, rectangle, circular or ellipse or other are irregularly shaped, when through hole 3 be shaped as rectangle the time; The sidewall length ratio of the length of through hole 3 and saggar 1 is 0.15-0.50, and the height of through hole 3 is 1-2cm.
The utility model is put into saggar 1 with anode material for lithium-ion batteries to be sintered in use, will be stamped then to put into the pusher furnace sintering on the saggar 1 of top cover 2 and get final product.The saggar 1 of the utility model atmosphere good fluidity during sintering in producing the pusher furnace of anode material for lithium-ion batteries has improved the uniformity of positive electrode performance, and has helped the serialization production of pusher furnace, enhances productivity; The positive electrode quality that sintering comes out is high, performance is good, and has characteristics simple in structure, long service life, suitable promoting the use of.
The technology that the utility model does not relate to all can realize through prior art.
