In technology, existing lithium battery processing technology has that processing efficiency is relatively low, the poor technical problem of crudy.
The content of the invention
It is an object of the invention to provide a kind of processing efficiency of the advantages that higher with processing efficiency, crudy is preferable
High lithium battery production technology.
The technical scheme is that：A kind of lithium battery production technology high in machining efficiency, the lithium high in machining efficiency
The step of battery production technology, includes：
（1）Mixed pulp：Need to get out electrode material, positive and negative pole material is closed in reactor slurry, i.e., in reaction vessel
Positive and negative pole material is made；
（2）Pole piece processed：The slurries made uniformly are applied to above electrode carrying object, then carry out baking piece, when toasting one section
Between, vapor away the moisture in slurries and other volatile organic matters, be screening after having dried piece, battery pole piece according to
Manufacture craft requirement is arranged in the appearance of needs；
（3）Winding：Positive and negative plate is separated through diaphragm paper, then electrode roll is around wrapping up to form battery core；
（4）Encapsulation：Battery core after completing loads within box hat, forms battery；
（5）Insulation monitoring：The battery produced is carried out entering line activating to the positive and negative pole material of battery, the battery by activation will
A passivating film is formed on both positive and negative polarity surface, tests its insulating properties；
（6）Vacuum drying：Using battery is dried in vacuo, the wet gas in battery to be injected is thoroughly discharged, ensures the product of battery
Matter；
（7）Fluid injection：Toward battery liquid-filling mouth injection electrolyte, should be completed in dry glove box relative humidity ＜ 1%RH with
Under.
In a preferred embodiment of the present invention, described baking a period of time is 6-12h.
In a preferred embodiment of the present invention, the electrode material includes soluble nickel, cobalt, manganese salt.
A kind of lithium battery production technology high in machining efficiency of the present invention, higher with processing efficiency, crudy is preferable
The advantages that.
Embodiment
It is described in detail with reference to presently preferred embodiments of the present invention, so that advantages and features of the invention can be more easy to
In being readily appreciated by one skilled in the art, apparent clearly defined so as to be made to protection scope of the present invention.
In one embodiment, a kind of lithium battery production technology high in machining efficiency, the lithium battery life high in machining efficiency
The step of production. art, includes：
（1）Mixed pulp：Need to get out electrode material, positive and negative pole material is closed in reactor slurry, i.e., in reaction vessel
Positive and negative pole material is made；
（2）Pole piece processed：The slurries made uniformly are applied to above electrode carrying object, then carry out baking piece, when toasting one section
Between, vapor away the moisture in slurries and other volatile organic matters, be screening after having dried piece, battery pole piece according to
Manufacture craft requirement is arranged in the appearance of needs；
（3）Winding：Positive and negative plate is separated through diaphragm paper, then electrode roll is around wrapping up to form battery core；
（4）Encapsulation：Battery core after completing loads within box hat, forms battery；
（5）Insulation monitoring：The battery produced is carried out entering line activating to the positive and negative pole material of battery, the battery by activation will
A passivating film is formed on both positive and negative polarity surface, tests its insulating properties；
（6）Vacuum drying：Using battery is dried in vacuo, the wet gas in battery to be injected is thoroughly discharged, ensures the product of battery
Matter；
（7）Fluid injection：Toward battery liquid-filling mouth injection electrolyte, should be completed in dry glove box relative humidity ＜ 1%RH with
Under.
Further illustrate, described baking a period of time is 6-12h, and the electrode material includes soluble nickel, cobalt, manganese salt.
Further illustrating, battery core principle：The reaction mechanism of lithium-ion electric core is the progress with discharge and recharge, and lithium ion exists
Insertion is deviate between both positive and negative polarity, and without the presence of lithium metal inside the battery core that shuttles back and forth, therefore lithium-ion electric core is safer
It is stable.The positive pole of battery core, which is coated on aluminium foil, forms positive plate, and negative pole is that lamellar graphite adds conductive agent and adhesive to be coated in copper foil base
Take, negative electrode layer graphite particle more advanced at present uses nano-sized carbon.The design of the security and battery core of battery core, material
And the factor such as control of production technology production process is closely related.In the charge and discharge process of battery core, the electrode of positive and negative pole material
Current potential is in dynamic change, and with increasing for charging voltage, positive electrode current potential constantly rises, the negative material electricity of embedding lithium
Position declines first, a longer potential plateau then occurs, when charging voltage is too high（>4.2V）Or due to negative electrode active material
When charge level density is relative to positive electrode surface density (C/A) ratio deficiency, the excessively embedding lithium of negative material, under negative pole current potential is then rapid
Drop, lithium metal is set to separate out (precipitation for not having lithium metal then under normal circumstances), so can be to the performance and security of battery core
Form and greatly threaten.The present invention provides a kind of lithium battery production technology high in machining efficiency, has processing efficiency higher, processes
The advantages that quality is preferable.
The embodiment of the present invention, but protection scope of the present invention is not limited thereto, any to be familiar with this area
Technical staff disclosed herein technical scope in, the change or replacement that can expect without creative work should all be contained
Cover within protection scope of the present invention.Therefore, protection scope of the present invention should be with protection model that claims are limited
Enclose and be defined.
