Description

A kind of high power stack type lithium ion battery
Technical field
The utility model relates to a kind of lithium ion battery, particularly a kind of high power stack type lithium ion battery.
Background technology
Along with popularizing of portable digital products such as mobile phone, digital camera, MP3, lithium ion battery has obtained great popularization and application with advantages such as its high-energy-density, volume are reasonable, easy to carry.Undoubtedly, the size of lithium ion battery power has extremely important meaning for battery.Lithium ion battery ubiquity of the prior art such as problems such as security performance are not high, power is not high, performance is lower, needs to be resolved hurrily.
The utility model content
The purpose of this utility model is to design a kind of high power stack type lithium ion battery in order to solve the problems of the technologies described above, and this lithium ion battery has the security performance height, the technical characterstic that power height and serviceability are high.
A kind of high power stack type lithium ion battery of the utility model includes 20 positive plates and 21 negative plates, barrier film between positive plate and the negative plate, and positive and negative lug, according to negative pole-barrier film-positive pole ... the mode of positive pole-barrier film-negative pole, intersect and stack composition, each pole piece is divided into two parts, a part scribbles slurry, another part is exposed collector, 20 exposed collectors of positive pole are welded on the same aluminium anode ear simultaneously, 20 exposed collectors of negative pole are welded on the negative electrode lug of same copper nickel plating simultaneously, and the bonding area of lug and collector is bigger.
As a kind of improvement of the present utility model, the positive and negative lug of battery is separately positioned on the both sides of battery.
As another kind of improvement the of the present utility model, the slurry length of smearing on the described positive plate is 155, and width is 90; The slurry length of smearing on the described negative plate is 158, and width is 93.
Described collector is aluminium foil just very, and negative pole is a Copper Foil.

Embodiment
Specifically describe design of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is an internal structure schematic diagram of the present utility model; As shown in Figure 1, a kind of high power stack type lithium ion battery of the utility model, include 20 positive plates 2 and 21 negative plates 1, has barrier film 3 between positive plate 2 and the negative plate 1, and positive and negative lug, according to negative pole-barrier film-positive pole ... the mode of positive pole-barrier film-negative pole, intersection stacks composition.Fig. 2 is a positive plate structural representation of the present utility model; Fig. 3 is a negative plate structural representation of the present utility model.As shown in Figures 2 and 3, each positive plate is divided into two parts, and a part scribbles anode sizing agent 4, and another part is exposed plus plate current-collecting body 5, and described collector 5 is an aluminium foil; Each negative plate is divided into two parts, and a part scribbles cathode size 6, and another part is exposed negative current collector 7, and described collector 7 is a Copper Foil.20 exposed collectors 5 of positive pole are welded on the same aluminium anode ear simultaneously, 21 exposed collectors 7 of negative pole are welded on the negative electrode lug of same copper nickel plating simultaneously, and the bonding area of lug and collector is bigger, so then resistance value reduces, help heavy-current discharge, meet the requirement of high power lithium ion cell.In order to improve the security performance of battery, the positive and negative lug of battery is separately positioned on the both sides of battery, has reduced the probability of battery short circuit effectively, and has improved safety in utilization.It is 155 μ m that the slurry of smearing on the positive plate 4 is preferably length, and width is 90 μ m; Slurry 6 preferred lengths of smearing on the negative plate are 158 μ m, and width is 93 μ m.
The contact area that the utility model has the advantages that lug and collector is bigger, and resistance value reduces, Be conducive to heavy-current discharge, meet the requirement of high power lithium ion cell; Exist owing to lug in addition The both sides of battery have been reduced the probability of battery short circuit effectively, and have improved safety in utilization.
