Description
Technical field
The utility model relates to polymer Li-ion battery sheet standardization profile die cavity technology field, and is special relevant with a kind of polymer Li-ion battery profile standard forming technology mould.
Background technology
China's lithium-ion battery energy industry has entered under the situation of high speed development, is that electric motor car energy and special trade and communication industry all begin the powerful electrochmical power source of high-energy is all begun to use widely.At present, both at home and abroad product diversity in the industrial production of high-energy polymer lithium ion battery, many specifications, standard unordered, connect different situation ubiquity, and the reason that this situation exists is because polymer Li-ion battery external packing aluminum plastic film is difficult to form the standard shape of solid material causes.Add that output both positive and negative polarity lug sheet metal is the free state that width, thickness differ, the profile and the connected mode that are difficult to for many years to form polymer Li-ion battery are difficult to formation standard system type.
Traditional polymer Li-ion battery is because battery anode ear material is aluminium, and negative electrode lug is copper material or nickel material, and the different solderabilities of its material are different.Form in the connection in series-parallel process of battery pack in assembling, each manufacturer is not owing to there is standardization profile technique, small-capacity cells or large capacity energy-storage battery are to weld bimetal leaf (every the plumbous nickel composite band of electricity) with the ultrasonic glistening light of waves connecting the traditional handicraft solution of using, and then the realization that is connected together of the brill nickel composite tape of each battery is connected in parallel; If negative pole copper polar ear and the connection of being connected then form cascaded structure with the nickel of battery bimetal leaf and another battery core and the bimetal leaf welding of copper paired (face-to-face) or aluminium and aluminium paired (face-to-face).This processing mode is owing to the complexity of processing, and operating efficiency and reliability are low.Because the repair welding operation of welding exists, cause the internal resistance of cell to increase the battery set charge/discharge Efficiency Decreasing, because welding dosage is inconsistent, cause each pad resistance difference, affected battery in groups uniformity and the harmonious important indicator of rear each battery, thereby reduced the cycle life of battery.And traditional welding procedure can't realize on high-energy, high power, large electric current polymer lithium ion power cell group.In addition, power battery pack and series connection amount are various, in the discharge work of large electric current, because the heating of battery, the accumulation of heat of battery pack, can cause battery consistency to reduce, battery produces and expands, the bad phenomenon such as the temperature height that each pad produces because of the difference of processing conditions is different, particularly to large electrokinetic cell, more excessive owing to weld interval, welding temperature is too high and be delivered to inside battery by the heat that cell polar ear forms, cause battery inside section barrier film to shrink, just, negative pole interface SEI rete destroys, can stay the electrical property that brings because of excess Temperature in internal short-circuit and electrical property variation shape and battery membranes surface change the cycle life reduction the potential safety hazard consequence.Its two, in order to solve above-mentioned deficiency, the board-like clamp mechanism of the employing that has connects.This kind mode can only realize the problem that local connection fittings are unified.But because battery appearance and connection are not the unified standard positioning moldings, the inherent variability that positive and negative lug is manufactured in the battery manufacture exists, remain different wide, narrow, thick, thin polymer battery chips and form the design that battery pack can form different connection members, in application process, be difficult to realize the system type assembling of connector and battery, become one of Research Challenges of present solution " high-energy, high power, large electric current " polymer lithium ion power cell profile and connection standard design and selection.
In order to address the above problem, the inventor designs a kind of polymer Li-ion battery profile standard forming technology mould, and this case produces thus.

Described battery pole ear standard contiguous block also comprises temperature sensor, offers for temperature sensor mounted installing hole in screw one side.
The framework outline of described glue-line posting is rectangle, and the position of corresponding battery pole ear offers and is fit to the groove that battery pole ear standard contiguous block card is put.
Profile is the geometric form that matches with cell shapes in the framework of described glue-line posting.
The profile medial surface has and somely carries out spacing convex tendon be used to withstanding battery in the framework of described glue-line posting.
The inner cavity size of described standard technology cavity and glue-line posting outer contour shape match, and battery pole ear standard contiguous block position offers the caulking groove for card discharge pond lug standard contiguous block, and described injecting glue briquetting is installed in the caulking groove.
After adopting such scheme, the utlity model has many beneficial effects:
At first, solved traditional polymer lithium-ion battery monomer battery at battery in groups in the process, the skimble-scamble difficult problem of shaping size.Strengthened simultaneously polymer lithium ion battery core flexible package profile intensity.
In fact, the battery pole ear standard contiguous block that provides in the utility model, solve that traditional temperature control sensing element is external, linkage function and mode loaded down with trivial details various, environmental reliability is low, has the problem of multiple inefficacy hidden danger.
It three has solved battery and has been difficult to form the difficult problem that standardization connects seriation in the process in groups, connects combination interface from battery and reduces and connect internal resistance, has improved the reliability, uniformity, the safety in utilization that connect.The Effective Raise joint efficiency reduces cost of labor, prolongs the cycle life of use battery pack more than 22%.
Its four this mould glue-line posting can be used stripping means, at glue injection body and battery in this posting after the solidifying and setting, its frame can separate by stripping means with the standard profile polymer Li-ion battery of typing, can make so repeatedly Reusability of same glue-line posting, greatly reduce the additional production cost that drops into into product.
In a word, the utility model not only can solve battery and be difficult to form the technical bottleneck that standardization connects seriation in the process in groups, and can effectively reduce invalid internal resistance accumulative total in the battery pack assembling, and improving battery pack electrical property consistency and security, the battery heat radiation is good.Make that the battery pack functional reliability is high, internal resistance is little, the electrical conduction performance is stable, solve the syndeton difficult problem at the potential safety hazard dead angle that conventional batteries exists, the complete unified purpose of the multinomial standardization of polymer Li-ion battery that realized.
