Abstract
The invention relates to a method for producing polymer battery, which comprises that: coiling anode sheet with anode ear and cathode sheet with cathode ear into one electric corn; welding several corns' parallel, while the anode ears are connected and the cathodes are connected. The invention has high efficiency, while each layer has anode ear, and it has low inner resistance to produce high-power battery.
Description
Technical field:
The present invention relates to a kind of production method of polymer battery.
Background technology:
The assembly technology of existing polymer battery has two kinds: one, coiling method; Two, laminated layer method.
The coiling method, anodal and negative pole all is a rectangular pole piece, and all is welded with a slice lug (as Fig. 1) at section start, the ellipsoid (as Fig. 2) of reeling exactly positive plate and negative plate close wind being formed.The advantage of this method: speed is fast, through the coiling worker of training in 2～3 months can accomplish 120-150 only/hour, if just faster with that speed of sutomatic winding machine.The shortcoming of this method: the finished product internal resistance of cell is bigger, causes the high-multiplying power discharge in-fighting big, so multiplying power discharging property is not as laminated batteries.
Laminated layer method is with the parallel cuboid that alternately is formed by stacking with negative plate of multi-disc positive plate (as Fig. 3,4).The advantage of this method: the finished product internal resistance of cell is little, can be used for making high-multiplying-power battery; The space availability ratio of battery is also very good, can produce high-capacity battery to greatest extent.The shortcoming of this method: the speed of lamination is slow, and production efficiency is low, and general lamination worker can only accomplish about 30/hour.
Summary of the invention:
Technical problem to be solved by this invention is to provide a kind of production method of polymer battery, the production efficiency height, and simultaneously, the internal resistance of cell of producing is little, can be used for making high-multiplying-power battery; The space availability ratio of battery is also very good, can produce high-capacity battery to greatest extent.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of production method of polymer battery is provided, the positive plate that will have an anode ear earlier is wound into an electric core with the negative plate with a negative electrode lug, again several described electric core parallel connections are welded together, wherein be welded to each other between the anode ear, be welded to each other between the negative electrode lug.
The invention has the beneficial effects as follows: because the present invention is wound into an electric core with positive plate and negative plate earlier, again several electric core parallel connections are welded together, wherein be welded to each other between the anode ear, be welded to each other between the negative electrode lug, in fact be equivalent to laminated batteries.So efficient is more much higher than lamination, make production process have coiling method body and produce the high characteristics of efficient, on each layer, all have lug simultaneously, the battery of producing is equally matched with the electric core of lamination, so its internal resistance is little, can be used for making high-multiplying-power battery.

Fig. 1 is conventional roll winding positive plate and negative plate structure chart;
The battery that Fig. 2 produces for the conventional roll winding;
Fig. 3 is laminated layer method positive plate and negative plate structure chart;
The battery that Fig. 4 produces for laminated layer method;
Fig. 5 is the production method positive plate and the negative plate structure chart of polymer battery of the present invention;
Fig. 6 is the single core strueture figure of the production method formation of polymer battery of the present invention;
The battery structure figure that Fig. 7 produces for the production method of polymer battery of the present invention.
Below in conjunction with accompanying drawing the present invention is described further:
Embodiment:
See also Fig. 5,6,7:
Be illustrated in figure 5 as the production method positive plate and the negative plate structure chart of polymer battery of the present invention, positive plate and negative plate all are strip, a lug 1 respectively is set on the limit of strip, be called anode ear on the positive plate, be called negative electrode lug on the negative plate, the shape of positive plate and negative plate is identical.Be wound into an electric core with the coiling method then, each electric core has an anode ear and a negative electrode lug.And then with the method for lamination several electric cores connection are welded together, wherein be welded to each other between the anode ear, be welded to each other between the negative electrode lug.So just form battery.
The present invention had both adopted the method for reeling, also adopted the method for lamination, produce battery, so efficient is more much higher than lamination with stacked lug, make production process have coiling method body and produce the high characteristics of efficient, simultaneously all have lug on each layer, the battery of producing is equally matched with the electric core of lamination, so, its internal resistance is little, can be used for making high-multiplying-power battery.
Essence of the present invention is exactly to adopt the method for reeling to produce the battery with stacked lug.
Essence of the present invention is exactly to adopt the method for reeling to produce the battery with stacked lug, why can reach this effect, and its reason just is to have adopted the pole piece with a plurality of lugs.Positive plate and negative plate all have only a slice, and be to finish with the method for reeling, so, efficient is more much higher than lamination, makes production process have coiling method body and produces the high characteristics of efficient, all has lug simultaneously on each layer, the battery of producing and lamination electricity core equally matched, so its internal resistance is little, can be used for making high-multiplying-power battery.Essence of the present invention is exactly to adopt the method for reeling to produce the battery with stacked lug.
