Abstract
The utility model discloses an ultra high power system pocket type lamination lithium ion battery structure, system pocket type lamination battery includes the positive plate of area diaphragm bag, and the negative pole piece, one side of positive plate of area diaphragm bag be equipped with anodal ear, one side of negative pole piece be equipped with the negative pole ear, positive plate and the negative pole piece electric core of range upon range of component in turn of area diaphragm bag to the anodal ear of the positive plate of umbilical cord diaphragm bag is in one side of electric core, and the negative pole ear of negative pole piece is in one side face to face of the anodal ear of electric core the utility model discloses when the superelevation multiplying power was discharged, the maximum temperature can descend about 30 DEG C, effectively reduces the fuel factor of battery to improve big current discharge's cycle life, both can improve discharge capacity and discharge the platform, also can prolong the cycle life of battery, simple structure, it is convenient to make.
Description
[technical field]
The utility model relates to a kind of ultra high power bag formula laminated lithium ion battery structure.
[background technology]
Lithium ion battery is a kind of green high-capacity rechargeable battery, and especially the performance of high-multiplying power discharge is far superior to the chargeable battery of other types all at present.
At present, the lithium ion battery with high-multiplying power discharge generally adopts lamination, and in order to the production efficiency that improves battery and rate of finished products, rises again the lamination of bag formula in recent years.The barrier film that two chip sizes are the same forms by thermosol chalaza the sack that is only had openings at one side, and positive plate is placed in one, more directly alternately laminated with negative plate, forms battery core; Then all pole pieces of just (bearing) just (are being born) together with tab welding with a slice, eventually pass other subsequent step and make battery; Positive and negative lug is positioned on the same top margin of battery, and simultaneously for preventing short circuit, the width of each lug must be less than the half of cell widths.
When battery carries out ultra-high magnifications electric discharge, its instant current value is very large, and the solder joint temperature rise on lug is the highest.Because positive and negative lug is at same top margin, two bond pad locations are close, cause temperature rise to superpose, and the temperature of cell body is very high, had a strong impact on the cycle life of battery.
[utility model content]
The purpose of this utility model is the shortcoming in order to overcome existing bag formula laminated lithium ion battery, provides a kind of structure simple, easily manufactured ultra high power bag formula laminated batteries structure.Adopt the lithium ion battery of this structure fabrication, when ultra-high magnifications discharges, maximum temperature can decline about 30 DEG C, effectively reduces the thermal effect of battery, both can improve discharge capacity and discharge platform, and also can extend the cycle life of battery.
The purpose of this utility model is achieved in that
A kind of ultra high power bag formula laminated lithium ion battery structure, it is characterized in that bag formula laminated batteries comprises the positive plate of band diaphragm bag, and negative plate, the side of the positive plate of described band diaphragm bag is provided with anode ear, the side of described negative plate is provided with negative electrode lug, the positive plate of described band diaphragm bag and the alternately laminated composition battery core of negative plate, and make the side of anode ear in battery core of the positive plate of band diaphragm bag, the negative electrode lug of negative plate is in the side, opposite of the anode ear of battery core.
A kind of ultra high power bag formula laminated lithium ion battery structure as above, is characterized in that width and the positive plate similar width of the anode ear of the positive plate of described band diaphragm bag; The width of the negative electrode lug of negative plate and negative plate similar width.
The utility model is when ultra-high magnifications discharges, and maximum temperature can decline about 30 DEG C, effectively reduces the thermal effect of battery, thus improve the cycle life of heavy-current discharge, both can improve discharge capacity and discharge platform, also can extend the cycle life of battery, structure is simple, easily manufactured.

Fig. 4 is cutaway view of the present utility model.
[embodiment]
A kind of ultra high power bag formula laminated lithium ion battery structure, described bag formula laminated batteries comprises the positive plate 1 of band diaphragm bag 10, and negative plate 2, the side of the positive plate 1 of described band diaphragm bag is provided with anode ear 11, the side of described negative plate 2 is provided with negative electrode lug 21, positive plate 1 and the alternately laminated composition battery core 3 of negative plate 2 of described band diaphragm bag, and make the anode ear 11 of the positive plate 1 of band diaphragm bag in the side of battery core, the negative electrode lug 21 of negative plate 2 is in the side, opposite of the anode ear 11 of battery core, that is anode ear and negative electrode lug be not on same top margin, but on relative two top margins.
The width of the anode ear 11 of the positive plate 1 with diaphragm bag and positive plate 1 similar width; The width of the negative electrode lug 21 of negative plate 2 and negative plate 2 similar width.The lithium ion battery made like this, when heavy-current discharge, because lug width (cross-sectional area) increases greatly, caloric value own will reduce, simultaneously due to two of positive and negative lug separation battery, the degree of its temperature rise superposition also alleviates greatly, and the overall temperature rise of battery is obviously declined.
