Abstract
The utility model belongs to the technical field of batteries, which comprises positive plates, negative plates and membranes separating the positive plates from the negative plates, wherein the negative plates are uniformly folded at an equal distance, and the positive plates present in a discrete lamellar shape and are respectively and fully clamped in the folding grooves of the negative plates. The cross section of the lamination of the negative plate is of a V shape or W shape. The battery with the lamination structure greatly reduces the layers of the lead-out ends of the negative plates, reduces the welding difficulty of lugs, and improves the production efficiency. The battery with the lamination structure also can effectively ensure that the negative plates fully cover the positive plates, and thereby improving the consistence and reliability of a battery cell, and having excellent power multiplying performance.
Description
Technical field
The utility model relates to a kind of field of batteries, relates in particular to the improved battery of a kind of lamination.
Background technology
The lamination of current battery has lamination and reels two kinds, lamination is fit to large-sized battery and high-multiplying-power battery, but its production efficiency is low, when the lamination number of plies is more, multilayer copper foil and the welding of nickel lug are difficult than difficulty and pole piece location, occur negative pole easily and can not cover anodal phenomenon fully; Winding-structure is not suitable for being applied to large-sized battery or high-multiplying-power battery.
The utility model content
Technical problem to be solved in the utility model provides and a kind ofly is fit to be applied to large-sized battery or high-multiplying-power battery, and the improved battery of the lamination of pole piece accurate positioning.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: the improved battery of a kind of lamination, comprise positive plate, negative plate and separate the barrier film of positive/negative plate, described negative plate is evenly equidistant folding, described positive plate is discrete single sheet, is clipped in fully respectively in the doubling groove of negative plate.
Further: in the improved battery of above-mentioned lamination, the lamination cross section of described negative plate is V-shaped, and the negative pole lamination is made up of several negative plates, and positive plate is clipped in " V " shape groove fully.Perhaps the lamination cross section of described negative plate is " W " shape, and positive plate is clipped in the doubling groove of negative plate fully.
Further again: in the improved battery of above-mentioned lamination, each opens negative plate and positive plate all has an electrode leads to client, can guarantee accurately drawing of electric weight like this.
Compared with prior art, in the improved battery of above-mentioned lamination, comprise positive plate, negative plate and separate the barrier film of positive/negative plate that described negative plate is evenly equidistant folding, described positive plate is discrete single sheet, is clipped in fully respectively in the doubling groove of negative plate.As everyone knows, the exit of negative plate generally is a Copper Foil, and Copper Foil is difficult to welding, adopted structure of the present invention after, the number of plies of the exit of negative plate is just a large amount of like this reduces, and has reduced lug and has welded difficulty, has improved production efficiency.The structure of this pole piece can also guarantee effectively that negative plate covers positive plate fully, and the consistency and reliability, the battery that have improved electric core have good high rate performance.
Description of drawings
Fig. 1 is the utility model negative plate lamination cross section when being " V " shape, the cross-sectional structure figure of its positive/negative plate, barrier film entire laminations;
Fig. 2 is the utility model negative plate lamination cross section when being " W " shape, the cross-sectional structure figure of its positive/negative plate, barrier film entire laminations;
Wherein 1 positive plate, 2 negative plates, 3 barrier films.
Embodiment
For the ease of those skilled in the art's understanding, the utility model structural principle is further described in detail below in conjunction with embodiment and accompanying drawing:
As Fig. 1: the improved battery of a kind of lamination, comprise positive plate 1, negative plate 2 and separate the barrier film 3 of positive/negative plate, described negative plate 2 is evenly equidistant folding, and described positive plate 1 is discrete single sheet, is clipped in fully respectively in the doubling groove of negative plate 2.The lamination cross section of described negative plate 2 is V-shaped, and the negative pole lamination is made up of several negative plates, and positive plate 1 is clipped in " V " shape groove fully.Each opens negative plate 2 and positive plate 1 all has an electrode leads to client.
As Fig. 2: the improved battery of a kind of lamination, comprise positive plate 1, negative plate 2 and separate the barrier film 3 of positive/negative plate, described negative plate 2 is evenly equidistant folding, and described positive plate 1 is discrete single sheet, is clipped in fully respectively in the doubling groove of negative plate 2.The lamination cross section of described negative plate 2 is " W " shape, and positive plate 1 is clipped in the doubling groove of negative plate 2 fully.
Above-mentioned only is preferred implementation of the present utility model, and in addition, the utility model can also have other implementations.That is to say that under the prerequisite that does not break away from the utility model design, any conspicuous replacement all should fall within the protection range of the present utility model.
