Opportunity.Positive electrode is the core and key of lithium ion battery.Wherein LiCoO2 Stability Analysis of Structures, specific capacity height, combination property are dashed forward
Go out, there is good chemical property, be the positive electrode that current commercial Li-ion battery generally uses.
At present in cobaltosic oxide preparation technology, prepare cobalt salt complex solution and aqueous slkali first, then by cobalt salt network
Polymer solution and aqueous slkali, which are poured into stirred tank, to be stirred, while air is passed through in stirred tank and carries out precipitation reaction, obtained precipitation
Cobaltosic oxide is obtained after thing centrifuge washing and drying.At present in this technique, the stirring reaction time needs 5-20 hours, and instead
Should be also insufficient, cobalt salt complex solution be present and aqueous slkali wastes, and process cycle is very long.
Utility model content
In view of the above problems, the purpose of this utility model is that providing a kind of reaction for being used to prepare cobaltosic oxide holds
Device, it is intended to solve existing cobaltosic oxide preparation technology time length, the incomplete technical problem of reaction.
The present embodiment adopts the following technical scheme that：
The reaction vessel for being used to prepare cobaltosic oxide includes cylinder, is provided with the cylinder and is hung down with tubular axis
Straight piston plate, blow vent is also provided with the cylinder, drive rod is also installed with the first member plate of the cylinder, the drive rod is stretched
Enter in cylinder and fixed with the piston plate, the right end plate inner surface of the cylinder is additionally provided with heating dish, the right side of the cylinder
It is also equipped with stirring flabellum in end plate, the driving machine for driving the stirring flabellum to rotate is additionally provided with outside the cylinder
Structure, two circle shower nozzles is additionally provided with the cylinder, the cylinder is provided with block, the right-hand member of the cylinder close to right-hand member Board position
Plate bottom is also provided with discharge gate, and switch valve is provided with the discharge gate.
Further, one layer of heat preservation layer is also wrapped up in the cylinder periphery.
The beneficial effects of the utility model are：The utility model sprays cobalt salt complex solution and aqueous slkali with spray pattern
Enter in reaction vessel, and high pressure oxygen is added in reaction vessel, pressure is larger in reaction vessel, and cobalt salt complex compound is molten
Liquid and aqueous slkali exist in the form of mist state so that in reaction vessel can with quick and complete reaction, react obtained precipitation can under
Reaction container bottom is sunk to, is promoted and is drained into follow-up agitator by piston plate, the W-response time greatly reduces.
Brief description of the drawings
Fig. 1 is the structure chart that the present embodiment provides the reaction vessel for preparing cobaltosic oxide.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
In order to illustrate technical scheme described in the utility model, illustrated below by specific embodiment.
As shown in figure 1, the reaction vessel for being used to prepare cobaltosic oxide includes cylinder 1, it is provided with the cylinder 1
The piston plate 2 vertical with tubular axis, blow vent 11 is also provided with the cylinder 1, drive is also installed with the first member plate of the cylinder 1
Lever 3, the drive rod 3 are stretched into cylinder and fixed with the piston plate 2, and the right end plate inner surface of the cylinder 1 is also set up
There is heating dish 4, be also equipped with stirring flabellum 5 in the right end plate of the cylinder, be additionally provided with outside the cylinder for driving institute
The drive mechanism 6 that stirring flabellum rotates is stated, is additionally provided with two circle shower nozzles 7 on the cylinder 1, the cylinder 1 is close to right end plate position
Install and be equipped with block 8, the right end plate bottom of the cylinder 1 is also provided with discharge gate 9, and switch valve 91 is provided with the discharge gate 9.
In the present embodiment, cobalt salt complex solution and aqueous slkali with two circle shower nozzles are corresponding connects, cobalt salt complex solution with
Aqueous slkali enters reaction vessel with spray pattern, and oxygen is passed through in reaction vessel from blow vent, and heating dish can control instead
Temperature in container, i.e. reaction temperature are answered, in the presence of flabellum is stirred, quickly flowing and mixing are equal for the reactant in reaction vessel
Even, pressure is larger in such reaction vessel, and cobalt salt complex solution and aqueous slkali exist in the form of mist state so that is reacting
Can be with quick and complete reaction in container, the precipitation for reacting to obtain can sink to reaction container bottom, then drive rod control piston
Disk moves, and piston plate releases reaction product, and through case verification, the reaction time in reaction vessel only needs a few minutes, although instead
Answer an addition of reaction solution in container limited, but from the point of view of the precipitated product of equal production volume is obtained, this reaction vessel
It is still able to save 30%-50% time.In addition, cobalt salt complex solution and aqueous slkali reaction are more complete, raw material wave is reduced
Take.
In order to control heat insulation effect, further, one layer of heat preservation layer 10 is also wrapped up in the periphery of cylinder 1, ensures in cylinder
Reaction temperature.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
