Abstract
A multilayer winding cylindrical cell and the fabrication process thereof comprise a separator, anode plates and cathode plates. The separator, the anode plates and the cathode plates are in multilayer, and the separator, the anode plates and the cathode plates are wound into a cylindrical roll core through layer lamination. The same electrode plates are connected in parallel with each other. The cylindrical cell fabricated by the invention through a multilayer winding technology can efficiently reduce the internal resistance of the cell owing to multilayer winding and mutual connection in parallel of the electrode plates. The size of the anode and the cathode plates using multilayer winding is shorter, and the work efficiency can be improved. The cell capacity can be infinitely increased through a parallel mode.
Description
Technical field
The present invention relates to a kind of big capacity cylindrical battery and manufacture craft thereof, relate in particular to a kind of multi-layer coiling column battery and manufacture craft thereof.
Background technology
Along with economic development and living standards of the people improve, people are more and more strong to the demand of the big capacity cylindrical battery of high-energy-density, cylindrical battery has remarkable advantages than rectangular cell, the cylindrical battery space availability ratio is higher, the battery table area is big in addition, radiating effect is better, and the internal structure compactness, rationally utilizes the useful space.
The coiling of cylindrical battery is confined to use individual layer positive plate, individual layer negative plate and uses barrier film to separate positive/negative plate at present, for small-capacity cells, take single laminate roll around being desirable, but for high capacity cell, the external diameter of its battery is bigger, if take single laminate roll around, so just need to make the very long positive/negative plate of length, this has just caused certain difficulty to coiling, use the positive/negative plate of length to bring certain difficulty, and the internal resistance of cell of producing is also bigger in manufacturing process.
Summary of the invention
The objective of the invention is to avoid weak point of the prior art and can effectively overcome above shortcoming, a kind of multi-layer coiling column battery and manufacture craft thereof that can reduce the internal resistance of cell and raise labour efficiency is provided.
For achieving the above object, the technical solution used in the present invention is:
A kind of multi-layer coiling column battery comprises: barrier film, positive plate, negative plate is characterized in that: described barrier film, positive plate and negative plate are multilayer, and by the stacked cylindrical roll core that is wound into then, identical pole piece is parallel with one another.
A kind of technology of making described multi-layer coiling column battery, it is characterized in that: at first barrier film is cut according to technological design length, require to put in order to install on the winding needle according to the number of plies cutting out good barrier film then, coiling one encloses barrier film earlier, then successively negative plate smooth be put into the barrier film middle, the lug end is preceding, lug is drawn the position upwards, close lamination, begin the negative pole of reeling, after making negative plate lug district all volume being gone up, the right hand is picked up positive plate then, the lug end after, lug is drawn the position upwards, successively is put into the barrier film middle; Step on foot-operated beginning of up-coiler and reel, positive and negative plate is adjusted on coiling limit, limit, makes volume core end face smooth, reels to finish the back left hand and pinch the volume core, pulls out with tweezers to stop adhesive tape and twine a circle rolling up the core outmost turns; With the counter-rotating of up-coiler furnishing, pinch the volume core with hand and step on the foot-operated counter-rotating that begins, will roll up pin behind the counter-rotating half-turn and pull out, will roll up core then and pull out.
The cylindrical battery that the present invention produces by multilaminate coiled technology since be multilaminate coiled, pole piece is parallel with one another, so just can effectively reduce the internal resistance of battery, the positive and negative electrode chip size of multilaminate coiled use is shorter, so can also increase work efficiency.Battery capacity can infinitely improve by parallel way.
Description of drawings
Figure is a structural representation of the present invention.
In the accompanying drawing: 1, barrier film; 2, positive plate; 3, negative plate.
Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments:
The present invention comprises as shown in the figure: barrier film 1, positive plate 2, negative plate 3, and barrier film 1, positive plate 2 and negative plate 3 are multilayer, and by the stacked cylindrical roll core that is wound into then, identical pole piece is parallel with one another.
The present invention makes the technology of multi-layer coiling column battery: at first barrier film is cut according to technological design length, require to put in order to install on the winding needle according to the number of plies cutting out good barrier film then, coiling one encloses barrier film earlier, then successively negative plate smooth be put into the barrier film middle, the lug end is preceding, lug is drawn the position upwards, close lamination, begin the negative pole of reeling, after making negative plate lug district all volume being gone up, the right hand is picked up positive plate then, the lug end after, lug is drawn the position upwards, successively is put into the barrier film middle.Step on foot-operated the beginning and reel, positive and negative plate is adjusted on coiling limit, limit, makes volume core end face smooth, reels to finish the back left hand and pinch the volume core, pulls out with tweezers to stop adhesive tape and twine a circle rolling up the core outmost turns.With the counter-rotating of up-coiler furnishing, pinch the volume core with hand and step on the foot-operated counter-rotating that begins, will roll up pin behind the counter-rotating half-turn and pull out, will roll up core then and pull out.
The cylindrical battery of producing by this technology is because multilaminate coiled (can reach 40 layers at most), and identical pole piece is parallel with one another, so just can effectively reduce the internal resistance of battery, and the pole piece size of multilaminate coiled use is shorter, so can also increase work efficiency.Battery capacity can infinitely improve by parallel way.
