Abstract
The invention relates to a method for preparing a battery cell of a high-capacity lithium ion battery for an automobile. The method comprises the steps of: (1), uniformly coating slurry on a current collector, drying, and preparing pole pieces after continuous rolling, continuous slitting, and continuous die cutting; (2) weighing and sorting and automatically printing the pole pieces subjected to die cutting; and (3), placing the printed pole pieces on a pole piece trough, and superposing the pole pieces in a Z shape to form the battery cell. According to the method for preparing the battery cell of the high-capacity lithium ion battery for the automobile, compared with the winding production process, the battery cell manufactured by laminated pieces has the advantages of uniform temperature distribution, small internal resistance of the battery, no stress inside the battery, good rate discharge and good safety of the battery and the like.
Description
Technical field
The invention belongs to the preparation field of lithium ion battery cell, particularly a kind of large volume automobile is with the preparation method of lithium ion battery cell.
Background technology
In recent years, along with the fast development of electric tool, electronic toy, electric bicycle, hybrid vehicle etc., increasingly high requirement has been proposed for the high power discharge ability of storage battery.The power-type lithium ion storage battery is owing to have preferably the high-power operation performance and high-energy-density and advantage such as light, thereby just promoted the use of above field step by step.
At present, the formation of the electrode cores of lithium battery mainly contains stacked and two kinds of main modes of takeup type.Wherein stacked to have a catchment effect even, and automatization level is high, and positive plate or negative plate are prone to realize thick typeization, the advantage that helps reducing cost; But the lamination type electric core lithium battery is higher to the required precision of process equipment; Especially the girth along with electric core positive plate and the die-cut edge of negative plate is multiplied; Cause being easy to generate burr in film-making and the assembling process, further can cause problems such as short circuit, qualification rate is low; The follow-up hidden danger of use is also higher, also safety problem can take place under the extreme case.Patent CN200620067095.X discloses a kind of coiled lithium battery cell; This takeup type electricity core is made simple; Film-making, assembling process are general to equipment precision requirement, and production efficiency is high, and cost is lower; But because there is the place of higher curvature in takeup type electricity core, fracture, the active material that in the process of positive plate and negative pole thickness of slab typeization, is easy to generate positive plate or negative plate problem such as come off.
And along with the increase of cell set capacity, volume of battery is increasing, and the heat that produces in the battery charge and discharge process is also increasingly high, causes away from the internal temperature of battery outer surface seriously higherly, is easy to generate thermal runaway, causes security risk.
Summary of the invention
Technical problem to be solved by this invention provides the preparation method of a kind of large volume automobile with lithium ion battery cell; This method is with respect to coiled production technology, and the electric core that adopts stacked production technology to produce has uniformity of temperature profile, the internal resistance of cell is little, inside is unstressed, multiplying power discharging reaches advantages such as battery security is good well.
A kind of large volume automobile of the present invention comprises with the preparation method of lithium ion battery cell:
(1) slurry evenly is coated on the collector, after the drying, behind continuous rolling, continuous itemize, continuous cross cutting, processes pole piece;
(2), the sorting of weighing, brush sheet automatically with the pole piece behind the above-mentioned cross cutting;
(3) pole piece behind the above-mentioned brush sheet is placed in the pole piece hopper, adopts the shape lamination of Z to become electric core.
The automatic fraction collector sorting of weighing is adopted in the sorting of weighing in the said step (2), and brushes sheet automatically and adopts automatically brush sheet machine to brush sheet automatically.
Lamination in the said step (3) adopts automatic lamination machine lamination.
Beneficial effect
(1) whole process using automation equipment in the present invention's electricity core manufacture process guarantees consistency of product, improves the qualification rate of product;
(2) the present invention is with respect to coiled production technology, and the electric core that adopts stacked production technology to produce has uniformity of temperature profile, the internal resistance of cell is little, inside is unstressed, multiplying power discharging reaches advantages such as battery security is good well.
