Abstract
The utility model discloses a fastening lithium ionic cell with a pressing structure, with the technical proposal being that the utility model includes a battery cover, a battery shell connected with the battery cover through an insulating sealing ring, and a chemical reaction layer, a liquid collecting element and an electrolyte which are placed in the battery shell, with the battery cover and/ or the battery shell are contacted with the chemical reaction layer through the pressing structure. Thanks to the pressing structure of the fastening lithium ionic cell, when the battery is inflated during the charging, the pressing structure can guarantee the good contact between the battery cover and/ or the battery shell and the chemical reaction layer, thus ensuring the good performance of the battery.
Description
Technical field
The utility model belongs to lithium ion battery, is specifically related to the buckle type lithium-ion battery.
Background technology
Electrochemical reaction layer in the existing buckle type lithium-ion battery directly contacts with battery cover, battery case.This battery is after charging, and the inner chemical reaction that takes place produces gas, makes battery case, battery cover bulging, causes battery cover, battery case to contact the heavy-current discharge performance of bad reduction battery with the chemical reaction layer.In order to make battery cover, battery case and electrochemical reaction layer keep excellent contact, the way that battery cover, battery case are welded by lead and electrochemical reaction layer is arranged; But production process complexity like this, efficient is low, is not suitable for large-scale production.
Summary of the invention
The purpose of this utility model is to provide a kind of buckle type lithium-ion battery with compressing structure, to solve the problem on the above-mentioned battery structure.
Technical solution of the present utility model is: the buckle type lithium-ion battery comprises battery cover, be connected battery case with battery cover by the insulated enclosure circle, the electrochemical reaction layer of establishing in it, collector and electrolyte, battery cover or/and battery case contact with electrochemical reaction layer by compressing structure.The lithium ion battery of this structure is owing to have compressing structure, and when battery charge generation bulging, compressing structure guarantees battery cover or/and battery case keeps excellent contact with electrochemical reaction layer all the time, thereby has guaranteed that battery has good performance.
Description of drawings
The buckle type lithium-ion battery that Fig. 1 elastomeric pad, pad branch are arranged
Fig. 2 elastomeric pad, pad are at the buckle type lithium-ion battery of the same side
The reeded buckle type lithium-ion battery of Fig. 3 battery cover and battery-shell surface
Fig. 4 battery-shell surface is fluted and the buckle type lithium-ion battery of pad arranged
Embodiment
Increasing compressing structure to battery has multiple implementation, illustrates four kinds here, and other existing structure in the battery is not this tired stating:
Mode one, as shown in Figure 1, end face is that the battery cover 1 on plane is the battery case 3 on plane by insulated enclosure circle 2 connection end faces, what reel in it is electrochemical reaction layer 6.Indent elastomeric pad 5 is located between battery cover 1 and the chemical reaction layer 6, and pad 4 is located between battery case 3 and the chemical reaction layer 6.Set up aluminium backing, can prevent that anode cover from oxidation taking place in charging process.Indent elastomeric pad 5 can be welded on the battery cover and also can not weld.Battery cover can certainly be made as positive pole, the setting of indent elastomeric pad and aluminium backing is with last opposite, this tired stating.
Mode two, as shown in Figure 2, end face is that the battery cover 1 on plane is the battery case 3 on plane by insulated enclosure circle 2 connection end faces, what reel in it is electrochemical reaction layer 6.Indent elastomeric pad 5 and aluminium backing 4-1 are located at the same side, among the figure they are located between battery case 3 and the chemical reaction layer 6.Aluminium backing 4-1 is located between indent elastomeric pad 5 and the chemical reaction layer 6.Indent elastomeric pad 5 can be welded on the battery case and also can not weld.Battery cover can certainly be made as positive pole, this not tired stating.
Mode three, as shown in Figure 3, its compressing structure is that the structure by battery cover 1-3 and battery case 3-3 self realizes, both connect by insulated enclosure circle 2.Be specially battery cover 1-3 and battery case 3-3 surface fluted 7-1,7-3, end face 8-1, the 8-3 of groove directly contacts with electrochemical reaction layer 6.Between as the utmost point shell of positive pole or polar cap and electrochemical reaction layer 6, can set up pad 4-3, prevent the anodal oxidation that in charging process, takes place.This with battery case 3-3 as positive pole.
Mode four, as shown in Figure 4, its compressing structure is that the structure by battery cover or battery case self realizes.End face is the battery case 3-3 of the battery cover 1 on plane by the surperficial fluted 7-3 of insulated enclosure circle 2 connections among the figure, and battery cover 1 directly contacts with electrochemical reaction layer 6, establishes aluminium backing 4-4 between battery case 3-3 and the electrochemical reaction layer 6.Equally also battery cover can be made as positive pole, this not tired stating.
Claims (5)
