The device of the utility model is simple in structure, can improve lower floor's powder atmosphere environment during cooperation roller hearth furnace multilayer sintering lithium ion batteries cathode materials, not only can improve the quality of product, can also prolong the life of casket -like bowl and roller hearth furnace roller stick, economic benefits is obvious.
Description
Technical field
This utility model relates to the auxiliary device of anode material for lithium-ion batteries roller way kiln, particularly a kind of anode material for lithium-ion batteries roller furnace multi-layer sintering saggar.
Background technology
Lithium ion battery is widely used in the fields such as digital 3C, intelligence wearing, electric tool, electronic toy (model plane, aircraft etc.), electric bicycle, electric bicycle, electric automobile and energy storage market at present.Lithium ion battery cell is mainly made up of four major parts such as positive pole, negative pole, barrier film, electrolyte, wherein positive electrode accounts for the 30～40% of lithium-ion electric core cost, and the anode material for lithium-ion batteries of existing market mainly has cobalt acid lithium, tertiary cathode material, LiFePO4 and LiMn2O4 etc..Synthesis for positive electrode is mainly prepared with high temperature solid-state method, sinter currently used most be roller furnace, roller furnace has captured most markets of anode material for lithium-ion batteries sintering due to advantages such as its atmosphere are easy to control, temperature field is homogeneous, yield is bigger.
Along with the continuous expansion in market, in the cooperation lower part positive electrode producer exploitation multi-layer sintering technology of roller furnace producer, promote anode material for lithium-ion batteries sintering output further, reduce sintering cost.But, multi-layer sintering faces the problems such as material atmosphere flowing in lower floor's saggar is the most smooth, causes lower floor's material excess agglomeration, affects product quality.On market, a large amount of surrounding opening saggars used are contemplated to improve sintering atmosphere design.But roller furnace advance during inevitably exist wander off, front and back set aside the problem touched, even if just having divided position with laser locator before Tui Jining.Due to front and back and left and right saggar contacts, the strong influence atmosphere of lower floor's material, cause aerofluxus smooth, not only affect product quality, the most serious service life shortening saggar.It is thus desirable to develop a kind of novel ion battery positive electrode multi-layer sintering saggar.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, this utility model provides a kind of anode material for lithium-ion batteries multi-layer sintering saggar.
The technical scheme that this utility model is used is mainly:
A kind of anode material for lithium-ion batteries multi-layer sintering saggar, described saggar includes that alms bowl base and bowl, described bowl are arranged on alms bowl base, and the edge on described alms bowl primitive period limit exceeds bowl corresponding sides, and the surrounding alms bowl wall of described bowl is provided with fire groove.
Further, the edge on described alms bowl primitive period limit exceeds bowl corresponding sides 10mm.
Further, the thickness of described alms bowl base and bowl is 8～12mm.
Further, described alms bowl base and bowl are square.
Further, described fire groove is inverted trapezoidal.
Further, the height of described fire groove is 15～20mm.
Further, the described fire length of groove is 0.4～0.8 with the length ratio of bowl corresponding sides.
Further, the height of described saggar is 75～95mm.
The beneficial effects of the utility model are:
Anode material for lithium-ion batteries multi-layer sintering saggar of the present utility model, owing to the edge on alms bowl primitive period limit is beyond bowl corresponding sides, alms bowl cardinal extremity face is bigger than the bottom surface of bowl, when roller furnace charging sintering, such saggar contains suitable material four row side by side and places bottom, upper strata can code equidimension routine saggar, owing to lower floor's saggar has suitable space between all around, when ensure that sintering, oven cavity atmosphere is unobstructed, lower floor's powder sintering is effect improved substantially, simultaneously because overall oven cavity atmosphere is unobstructed, it is beneficial to alkaline gas discharge, significantly increase the life-span of saggar, reduce production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
With reference to Fig. 1, a kind of anode material for lithium-ion batteries multi-layer sintering saggar, saggar includes alms bowl base 1 and bowl 2, and bowl 2 is arranged on alms bowl base 1, and the edge of alms bowl base 1 periphery exceeds bowl 2 corresponding sides, and the surrounding alms bowl wall of bowl 2 is provided with fire groove 3.
In one specific embodiment of this utility model, the size of alms bowl base 1 is 340mm*340mm, and the size of bowl 2 is 320mm*320mm, and the edge of alms bowl base 1 periphery exceeds bowl 2 corresponding sides 10mm, so alms bowl base 1 end face is more than the bottom surface of bowl 2；The thickness of described alms bowl base 1 and bowl 2 is 10mm；Described fire groove 3 is in inverted trapezoidal, and the height of fire groove 3 is 15mm；The fire length of groove 3 is 0.6 with the length ratio of bowl 2 corresponding sides；The height of saggar is 85mm.
Due to alms bowl base 1 edge length of side 10mm more corresponding than bowl 2, when sintering uses four row side by side, adjacent saggar spacing all around is 2cm, and during roller-way is advanced, spacing will not change, and has greatly improved the concordance of calcination environment in burner hearth；Upper strata can use the saggar big with bowl 2 grade, owing to lower floor's saggar is all around in close contact, it is ensured that saggar will not change during advancing, and during lower floor's powder sintering, atmosphere is unobstructed, has bigger improvement to powder sintering.This utility model can reduce production cost, improving product performance, extends saggar and roller-way furnace roller rod service life, and economic benefit is obvious.
Described in above-described embodiment and description, principle of the present utility model and most preferred embodiment are simply described; on the premise of without departing from this utility model spirit and scope; this utility model also has various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.
