Abstract
The utility model discloses a saggar for sintering ternary composite anode material powder for a lithium battery. A saggar body (2) is a frame made of metallic material, and separation plates (1) are arranged in the saggar body (2). The saggar for sintering the ternary composite anode material powder for the lithium battery has the advantages that the structure is simple, the design is reasonable, and the whole saggar is formed by welding metallic plates, so that the thermal conductivity and thermal-shock resistance of the saggar can be better; the saggar cannot crack or be damaged in repeated use, so that the service life of the saggar is prolonged; the thermal distribution inside the saggar is even, and thus the yield of products is increased; and the cost is greatly saved.
Description
Technical field
The utility model belongs to the lithium battery manufacture field, relates in particular to a kind of saggar of sintering lithium battery tertiary composite positive pole powder.
Background technology
In recent years, baking sagger for lithium battery material is that the simple alteration of form of doing of traditional high temperature resistant saggar is used for the roasting of lithium electric material basically.Traditional high temperature resistant saggar is generally cordierite, mullite, quartziferous and corundum quality high-temperature saggar.These high temperature resistant saggars have higher erosion-resisting characteristics and temperature vibration stability; But because the used raw material of synthesizing lithium ion positive electrode in building-up process, can decompose the generation penetrating power and the strong lithia of reactivity corrodes high temperature resistant saggar; Cause the saggar cracking; Reduce service life greatly, can only use about 3 times when wherein the high temperature resistant saggar of mullite is used for synthesizing iron lithium phosphate.If directly use above-mentioned high temperature resistant saggar to produce, can increase the production cost of lithium battery greatly.
The utility model content
The utility model technical problem to be solved is to provide a kind of and does not ftracture, and can use repeatedly, and the uniform lithium battery tertiary composite positive pole powder sintering that is heated is used saggar.
The technical scheme of the utility model is following: a kind of lithium battery tertiary composite positive pole powder sintering is used saggar, and its key is: the frame that said saggar body (2) is made for metal material is provided with dividing plate (1) in this saggar body (2).The needs of saggar body (2) during according to agglomerated material can be square frame, circle frame and polygon frame.Metal material has high-termal conductivity and excellent mechanical property; Can make saggar bear frequent heating and cooling process, use damages of not ftractureing repeatedly, when dividing plate being set inside simultaneously and making sintering; Temperature is more even, and it is better under the temperature together trielement composite material to be carried out sintering effect.
Above-mentioned saggar body (2) is welded by stainless steel, and said dividing plate (1) also is a stainless steel material, and this dividing plate (1) is fixed by welding in the saggar body (2) separates saggar body (2) inner chamber.Select for use the stainless steel heat-conducting effect better, more can bear frequent heating and cooling process.
Beneficial effect: the utility model the utility model is simple in structure, reasonable in design, and whole saggar is welded by metallic plate, makes the thermal conductivity of saggar and thermal shock resistance better; Use the damage of can not ftractureing repeatedly, increased the service life of saggar; The saggar internal heat is evenly distributed, and has improved the yield rate of product; Provide cost savings greatly.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Like Fig. 1, shown in Figure 2, a kind of lithium battery tertiary composite positive pole powder sintering is used saggar, and the shaped as frame that saggar body 2 is made for metal material is welded by stainless steel, is provided with dividing plate 1 in this saggar body 2.Dividing plate 1 also is a stainless steel material, and this dividing plate 1 also is fixed by welding in the saggar body 2 separates saggar body 2 inner chambers.
Although more than combine accompanying drawing that the preferred embodiment of the utility model is described; But the utility model is not limited to the above-mentioned specific embodiment; The above-mentioned specific embodiment only is schematic rather than determinate, and those of ordinary skill in the art is under the enlightenment of the utility model, under the prerequisite of the utility model aim and claim; Can make multiple similar expression, such conversion all falls within the protection domain of the utility model.
