Abstract
The utility provides a disposal lithium-manganese battery cathode pole lug which comprises a metal belt and a rubber film, the rubber film is transversely adhered on the metal belt to separate the metal belt into two parts which are not equal in length, and the longer part of the metal belt is in the concave-convex structure that one surface is concave and the other surface is raised. According to the disposal lithium-manganese battery cathode pole lug, the concave-convex structure that one surface is concave and the other surface is raised is formed on the longer part of the metal belt, when the disposal lithium-manganese battery cathode pole lug and a lithium belt are adhered, the pole lug and the lithium belt are directly adhered in a press fit mode, a traditional packing adhesion mode is not required, one half of the application amount of the lithium belt is saved, production cost is lowered, complexity of production processes is simplified simultaneously, and production efficiency is improved.
Description
Technical field
The utility model relates to the battery raw material field, the metallic conductor that particularly from battery core, both positive and negative polarity is extracted in the lithium ion polymer battery product, and this conductor is called lug.
Background technology
Lithium-manganese cell: full name lithium-manganese dioxide battery (Lithium-manganese dioxide, Li-MnO2).Lithium manganese primary cell is to use the lithium metal as negative electrode and anode manganese dioxide, is dissolved in the organic solvent with lithium salts.Compact lithium cell is in daily use, portable electric appts, and such as palmtop PC, wrist-watch, video camera, digital camera, thermometer, calculator, the BIOS of notebook computer, communication apparatus, telecar door lock.They have many shapes and size, with common kind, and " coin " type manganese kind of 3 volts, general diameter is 20 millimeters and 1.6-4 millimeters thick.The heavy electricity needs of many these equipment makes an attractive especially selection of lithium ion battery.Lithium battery particularly can be supported of short duration, heavy equipment at an easy rate, and such as digital camera present requirements, and they keep long time higher than the voltage of alkaline battery.
Lug is a kind of raw material of lithium ion polymer battery and lithium-manganese cell product.The battery of mobile phone of for example using in our life, Bluetooth battery, Notebook Battery etc. all need to use lug.Battery is a minute both positive and negative polarity, and lug is exactly the metallic conductor that from battery core both positive and negative polarity is extracted, and the popular ear of saying the battery positive and negative polarities is the contact point when discharging and recharging.This contact point is not that copper sheet of our the battery appearance seen, but a kind of connection of inside battery.Lug is divided into three kinds of materials, and the positive pole of battery uses aluminium (Al) material, and negative pole uses nickel (Ni) material, and negative pole also has copper nickel plating, and (material of Ni-Cu), they all are to be composited by film and metal tape two parts.
Film is the part that insulate on the lug, and its effect prevents from when being cell package being short-circuited between metal tape and the aluminum plastic film, and when encapsulation is bonded together by heating (about 140 ℃) and aluminum plastic film hot-melting sealed and prevents leakage.A lug is clipped in the middle metal tape by two films.The film that existing market is used has three kinds in black glue, white glues and individual layer glue.Black film commonly used is three-decker: melanin, 66 ℃ of fusing points; PE, 105 ℃ of fusing points; PP, 137 ℃ of fusing points.
At present, the negative lug of a lithium-manganese cell comprises a nickel strap and a film, film is bonded in the top of nickel strap, when using this, the negative lug that from battery core, negative pole is extracted be by with battery core in the lithium band be connected with negative pole again after bonding, present way be adopt twice nickel strap width the lithium band carry out bonding at nickel strap two sides parcel nickel strap, like this, with using more lithium band, increased cost, cause waste.
The utility model content
For the negative lug that solves a present lithium-manganese cell in use, need to adopt twice nickel strap width the lithium band carry out bondingly at nickel strap two sides parcel nickel strap, with using more lithium band, increased cost, wasting deficiency, simultaneously production technology relative complex.An a kind of lithium-manganese cell negative lug is provided.
The technical solution of the utility model is: a lithium-manganese cell cell cathode ear pole, comprise metal tape and film, described film laterally sticks on the upper of described metal tape, metal tape is separated into the two parts that are uneven in length, forms the convex-concave structure of a pit one side projection in the long part of described metal tape.
Further, in the above-mentioned lithium-manganese cell negative lug: in the described convex-concave structure, pit is that diameter is roughly half circular pit of described metal tape bandwidth, on described metal tape both sides one group of pit is arranged respectively, described two groups of pit mutual dislocation.
Further, in the above-mentioned lithium-manganese cell negative lug: described metal tape is nickel strap.Described film is individual layer glue, sticks on the one side of described metal tape.
Form the convex-concave structure of a pit one side projection in the utility model owing to the long part at metal tape, carrying out when bonding with the lithium band, adopt the mode of pressing to make lug and lithium band directly bonding, need not use traditional parcel bonding mode, saved the use amount of half lithium band, reduced production cost, the complexity of having simplified simultaneously production technology has improved production efficiency.
Below in conjunction with specific embodiment the utility model is done comparatively detailed description.
Description of drawings
Fig. 1 is the very much following schematic diagram of ear of the utility model.
Among the figure: 1, metal tape, 2, film, 3, convex-concave structure.
Embodiment
Embodiment 1, as shown in Figure 1, present embodiment is an a kind of lithium-manganese cell negative lug, comprise metal tape 1 and film 2, film 2 is individual layer glue, laterally sticks on the one side of metal tape 1, metal tape 1 is separated into the two parts that are uneven in length, metal tape 1 is nickel strap in the present embodiment, and other locally can use other metallic conductor, such as the copper nickel plating (material of Ni-Cu).In the lug of present embodiment, form the convex-concave structure 3 of a pit one side projection in the long part of nickel strap.In the convex-concave structure 3, pit is that diameter is roughly half circular pit of nickel strap bandwidth, on the both sides of nickel strap one group of pit is arranged respectively, two groups of pit mutual dislocation.
As shown in Figure 1, the lug of present embodiment is that a kind of lower part of the lug nickel sheet that in use uses is longer, is evenly equipped with two groups of pits in this part, and the diameter of the pit roughly width with nickel strap is identical, two groups of pits and mutual dislocation.The another side of nickel strap corresponding with pit be exactly projection.These pits and projection are to be stamped to form by the one side of stamping machine from nickel strap.The lug of present embodiment is particularly suitable for automated production.
During use, the lithium band is bonded in one side of the band projection of nickel strap, has arranged two group projections owing to have uniform here, increased greatly the contact area of nickel strap and lithium band, can just can lithium band and nickel strap is firmly bonding when the lithium band only has the nickel strap width.
