Abstract
The utility model discloses a device for increasing a contact area of materials with air. The device comprises a block dividing device and a saggar, and the device is characterized in that a protrusion is provided under a cover plate of the block diving device. The protrusion is additionally provided under the block divider, the contact area of the materials with the air is effectively increased if a consistent sintering atmosphere is guaranteed. The residual amount of a volatile impurity of Li-ion battery materials is effectively reduced in the sintering process in the application of the sintering of Li-ion powder materials.
Description
Technical field
The utility model belongs to lithium electricity powder body material sintering art, relate to a kind of pressure alms bowl blocking devices, relating to more specifically a kind ofly can effectively increase material and air contact area, reduces the pressure alms bowl blocking devices of lithium electric material volatile impurity residual volume in sintering process.
Background technology
The content of impurity element and compound and kind are one of factors that influences material property.Different materials is also different to the tolerance of the content of impurity element and compound and kind.Such as the content height of sulphur, phosphorus, arsenic, potassium, sodium, fluorine etc. in the steel industry, generally will influence the quality of steel.In the lithium electricity positive and negative pole material industry, sulfate radical, lithium carbonate, lithium hydroxide etc. also all belong to the impurity that influences performance.
Be example with lithium electricity positive electrode, lithium electricity positive and negative pole material generally comprises negative materials such as positive electrode such as cobalt acid lithium, polynary, LiMn2O4, LiFePO4 and lithium titanate, carbon.Sulfate radical content height in the material can increase the internal resistance of battery.Simultaneously along with the use of lithium ion battery, thereby can form the performance that corrosion influences battery at electrode slice.And the residual volume height of lithium carbonate and lithium hydroxide in the material can cause internal resistance to add equally, can make battery a large amount of aerogenesis in use in addition, causes the bulging of battery to break and then influences service life, and serious also can cause security incident.
In order to address these problems, the general way of production firm is as follows: 1) select the transistion metal compound of low sulfur content and the raw materials of compound of lithium for use; 2) suitably raise sintering temperature, impel conversion and the volatilization of these several impurity; 3) ventilation in specific warm area increase sintering process makes material contact more oxygen in order to form volatile phase, and is accelerated to discharge by bigger ventilation.But these methods all can cause the rising of enterprise's production cost, also are unfavorable for energy-saving and emission-reduction simultaneously.In addition, also can not arbitrarily promote sintering temperature and ventilation in the actual production process, otherwise may be to the influence of damaging property of material property.
Therefore need a kind of cost low, the effective ways of sintering atmosphere unanimity or device reach the purpose that reduces product impurity and guarantee the product homogeneity.
Summary of the invention
The utility model provides a kind of device that strengthens material and air contact area, can improve the gap of compacting material inside when improving dress alms bowl amount as much as possible, and the contact area of increase and air promotes the discharge of volatile impurity in sintering process; Optimization simple in structure, sintering atmosphere uniformity height.
To achieve these goals, technical solutions of the utility model are as follows:
A kind of device that strengthens material and air contact area includes block device and saggar etc.
In the said apparatus, the outer of described block device cover plate and saggar or interior along measure-alike;
In the said apparatus, protrusion is arranged at described block device cover plate bottom; Described protrusion is shaped as a kind of or wherein several in the similar type such as needle-like, column, class column, cutter shape, sheet, taper or long rib shape; Described protrusion length is not more than the saggar degree of depth, can all insert in the saggar;
In the said apparatus, described block device cover plate is provided with handrail.
This device can with the supporting use of automatic, semi-automatic Earthen bowl pressing machine.When the block device cover plate pressed material downwards, the protrusion of block device cover plate bottom is movement therewith also, stopped to press down behind block device cover plate contact saggar upper edge.Material can difformity and position occur according to shape and the distribution of protrusion in the saggar depression and hole can effectively increase and control the contact area of material and air in the space of material and the sintering process, increase sintering degree, reduction alkaline impurities content.
The pressure alms bowl device that the utility model provides by the bottom protrusion is set, can effectively increase material and air contact area; Simple in structure, it is low to have a cost, the homogeneity of product advantages of higher.

The specific embodiment
The utility model is that a kind of improved pressure alms bowl device for lithium electric material sintering is provided to this area, below specifies the utility model by drawings and Examples, but is not used for limiting scope of the present utility model.
Embodiment 1
A kind of pressure alms bowl device that strengthens material and air contact area, as shown in Figure 1, comprise block device cover plate 1 and saggar 4, be useful on the needle-like protrusion 2 that increases material and air contact area on the block device cover plate, protrusion 2 length are slightly less than the saggar degree of depth, block device cover plate 1 size is identical with saggar 4 outside dimensions, and block device cover plate 1 is provided with handrail 3.
When block device cover plate 1 presses down, drive protrusion 2 and press downwards, stop motion behind block device cover plate 1 contact saggar 4 upper edges.
A kind of pressure alms bowl device that strengthens material and air contact area, as shown in Figure 2, comprise block device cover plate 1 and saggar 4, be useful on the cutter shape protrusion 2 that increases material and air contact area on the block device cover plate, protrusion 2 length are less than the saggar degree of depth, along measure-alike, block device cover plate 1 is provided with handrail 3 in block device cover plate 1 size and the saggar 4.
When block device cover plate 1 presses down, drive protrusion 2 and press downwards, stop motion behind protrusion 2 contact saggars 4 bottom surfaces.
