Abstract
The utility model relates to a winding laminated lithium battery, comprising a couple of positive and negative electrode tablets and a diaphragm, which nips the diaphragm between the positive and the negative electrode tablets as a winded single cell. Two or more single cells, which are positioned in a line, with each of the positive/negative electrode tablets aligned, are welded with a lead lug derived from the package. The utility model, which is able to figure out the welding difficulty of large-capacity laminated lithium battery, has the advantages of simple operation and high security, smaller internal resistance, lower thermal effects and high discharging performance.
Description
Technical field
The utility model coiling lamination-type lithium battery electric core belongs to field of batteries, particularly relates to a kind of improvement technology that adopts convoluted structure lithium cell.
Background technology
At present, convoluted electric core structure of lithium battery all is an electric core, positive plate anode ear of burn-oning,, the negative plate negative electrode lug of burn-oning, separated by barrier film between the two, coiling forms, the internal resistance of cell height of doing, heavy-current discharge temperature height, discharge platform is low, and battery security is affected, single convoluted electric core structure of lithium battery, to be difficult to operation when pole piece is oversize, the battery capacity of being done is limited.At present, the lamination-type electric core structure of lithium battery all is that multi-disc positive plate and multi-disc negative plate are laminated by the barrier film separation, and positive/negative plate is many, and lamination production efficiency is low; The too many number of plies is difficult to welding, is also limiting the capacity of battery.
The utility model content
The purpose of this utility model is to avoid the deficiencies in the prior art part and provides a kind of electric in-core resistance little, and the heavy-current discharge temperature is low, the discharge platform height, and the capacity with battery amplifies easily, produces the convoluted lithium battery electric core that efficient is high easily.
The utility model can be achieved through the following technical solutions, it is by just, negative plate and barrier film are formed, barrier film is positioned between positive/negative plate, just, negative plate is provided with lug, positive/negative plate and barrier film are successively reeled to same direction by the volume core anchor clamps of special use, and maintenance positive/negative plate, align all the time in the center of barrier film Width, tensioning dynamics unanimity, just, negative plate and membrane coil are around the electric core of the list that forms, the electric sandwich layer of coiling list more than 2 or 2 stacks, the positive and negative lug of each single electric core aligns respectively, overlapping, it is welded together that anode ear after overlapping and outer positive pole draw lug, it is welded together that negative electrode lug after overlapping and outer negative pole draw lug, and one aligns, negative outer lug is derived outside the pack case.
The utility model adopts coiling lamination-type lithium battery electric core new construction, and pole piece shortens easy operating, and institute's internal resistance of cell of doing is little, and the heavy-current discharge temperature is low, and battery security improves.The electric sandwich layer of list of reeling is gathered into folds, and the capacity with battery amplifies easily, and the number of plies of welding significantly reduces, and has solved the welding difficult problem of the too many number of plies of the pure lamination-type lithium battery electric core of large capacity single.
Description of drawings
Accompanying drawing 1 is convoluted lithium battery monomer core strueture.
Accompanying drawing 2 is the utility model electric core structure of lithium battery schematic diagrames.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As accompanying drawing 1, shown in the accompanying drawing 2, coiling lamination-type lithium battery electric core of the present utility model is by positive plate 7, negative plate 8 and barrier film 9 are formed, barrier film is positioned between positive/negative plate, positive plate is provided with anode ear 10, negative plate is provided with negative electrode lug 11, positive/negative plate and barrier film are successively reeled to same direction by the volume core anchor clamps of special use, and maintenance positive/negative plate, align all the time in the center of barrier film Width, tensioning dynamics unanimity, be wound into single electric core, electricity core 1 and electric core 2 are stacked together, the positive and negative lug of each single electric core aligns respectively, overlapping, it is welded together that anode ear 3 after overlapping and outer positive pole draw lug 5, and it is welded together that the negative electrode lug 4 after overlapping and outer negative pole draw lug 6, and one aligns, negative outer lug is derived outside the pack case.
Claims (2)
1. coiling lamination-type lithium battery electric core, it is made up of positive and negative plate and barrier film, barrier film is positioned between positive/negative plate, positive and negative plate is provided with lug, it is characterized in that positive and negative plate and membrane coil are around the electric core of the list that forms, the electric sandwich layer of coiling list more than 2 or 2 stacks, and the positive and negative lug of each single electric core aligns respectively, overlapping.
2. coiling lamination-type lithium battery electric core according to claim 1, it is welded together to it is characterized in that anode ear after overlapping and outer positive pole draw lug, and it is welded together that negative electrode lug after overlapping and outer negative pole draw lug, outside a pair of positive and negative outer lug derivation pack case.
