The 30~40% of sub- battery core cost, the anode material for lithium-ion batteries of existing market mainly have cobalt acid lithium, tertiary cathode material,
LiFePO4 and LiMn2O4 etc..In the numerous synthetic method of this kind of material, high temperature solid-state method is due to its simple process, pollution
The advantages that few and be widely adopted.In the pyroreaction process of the method, roller furnace is because its atmosphere is easy to control, temperature field is equal
First, yield is larger, cost is low, the advantages that being easy to implement automation and be used more.
With the continuous expansion in market, there is higher demand to yield and efficiency, under the cooperation of roller furnace producer
Part positive electrode producer develops multi-layer sintering technology, so as to lift anode material for lithium-ion batteries sintering output, reduces sintering
Cost.However, multi-layer sintering faces the problem of flowing of material atmosphere is not smooth, and levels atmosphere is uneven in lower floor's saggar, cause
Lower floor's material excess agglomeration, levels product quality differ.In order to improve atmosphere circulation problem, existing alms bowl body four in the market
The saggar of week opening design, but actual production proves that this class formation saggar still fails to improve atmosphere circulation well；
Have the design that some saggars have alms bowl pin, but its alms bowl pin is cusp design, contact area is too small, be only applicable to horizontal sliding road enter stove and
It is not suitable for raceway stove, is waved because can be shaken in roller-way when entering stove, multilayer saggar is also easy to because of lasting shake when being superimposed
And the dislocation between saggar occurs, cause Ka Dao.In addition, traditional saggar is not provided with prominent anchor point, even if promoting
Just position, or easily error are got well with laser locator point before.Therefore need to develop a kind of roller furnace, available more of being applied to
Stacking plus the situation of sintering, the good anode material for lithium-ion batteries sintering saggar of atmosphere aeration.
The content of the invention
The problem of existing for prior art, present invention aims at providing, a kind of anode material for lithium-ion batteries high temperature is anti-
Using saggar, atmosphere circulation effect, service life length are which improved, and strengthen gas when being superimposed pyroreaction side by side for multilayer
Atmosphere convection current and the effect of heat transfer.
The present invention adopts the technical scheme that：A kind of anode material for lithium-ion batteries pyroreaction saggar, including bowl,
The bowl includes alms bowl bottom and encloses the alms bowl wall for being located at surrounding on the alms bowl bottom, and communication port, the alms bowl bottom are offered on the alms bowl wall
Lower surface offers circulation groove.
Preferably, the circulation groove is vertically installed with two, is be arranged in parallel respectively with the alms bowl wall.
As the further improvement of above-mentioned technical proposal, the alms bowl wall periphery is provided with bound edge, the bound edge bottom and institute
It is concordant to state alms bowl bottom surface, alms bowl pin is provided with described four angles in bowl lower surface, is advantageous to improve multilayer when being superimposed side by side
The effect of atmosphere circulation.
As the further improvement of above-mentioned technical proposal, the alms bowl pin uses chamfer prism-frustum-shaped structure, improves multi-laminate
The stability of added-time.
As the further improvement of above-mentioned technical proposal, the communication port is arranged on the alms bowl wall upper edge, described in four
Communication port is respectively along alms bowl bottom center line symmetrical setting.
As the further improvement of above-mentioned technical proposal, the communication port uses inverted trapezoidal shape structure.
As the further improvement of above-mentioned technical proposal, it is separately provided on described four angles of bound edge as laser positioning
Device provides the projection of positioning.
As the further improvement of above-mentioned technical proposal, the bowl is the cube structure of upper end open.
The beneficial effects of the invention are as follows：Compared with prior art, a kind of lithium ion cell positive material provided by the invention
Expect pyroreaction saggar, not only alms bowl wall is provided with communication port, and is provided with circulation groove at alms bowl bottom, when bowl is overlapped,
Atmosphere circulation effect is enhanced, improves the pyroreaction effect of lower floor's material, is discharged beneficial to alkaline gas, significantly increase alms bowl
In the life-span of body, reduce production cost.
Brief description of the drawings
Fig. 1 is a kind of three-dimensional structure diagram of anode material for lithium-ion batteries pyroreaction saggar embodiment of the present invention.
Fig. 2 is the upward view of Fig. 1 embodiments.
Fig. 3 is schematic diagram of Fig. 1 embodiments when multilayer is superimposed use side by side.
Embodiment
It is the structure chart of preferred embodiment provided by the invention as shown in Figure 1.It is a kind of in the present embodiment with reference to figure 1 and Fig. 2
Anode material for lithium-ion batteries pyroreaction saggar, including bowl 1, bowl 1 are the cube structure of upper end open, including alms bowl
Bottom 2 and the alms bowl wall 3 for being located at the surrounding of alms bowl bottom 2 to be enclosed, communication port 31 is offered on alms bowl wall 3, the lower surface of alms bowl bottom 2 offers circulation groove 21,
