Description
[technical field]
The utility model relates to lithium ion battery field, relates in particular to a kind of internal temperature test structure of lithium ion battery.
[background technology]
Lithium ion battery is owing to having higher energy density, higher operating voltage, safety, advantages such as environmental protection and be widely used in mobile electronic device, wearable device and electric tool, the fields such as electric motor car.Due to lithium ion battery neither be absolute safety, particularly electrokinetic cell, operation process in also there will be the situations such as thermal runaway to cause battery explosion, therefore, the security performance of the battery of lithium ion is the focus that we pay close attention to always.
Aspect the safety Design of battery, the temperature control aspect to battery particularly, common method is the outside table temperature of test battery, and to internal temperature of battery, particularly the analysis of volume core segment Temperature Distribution situation in charge and discharge process of battery is usually ignored by people, as can not be the construction or design of battery core made correctly and being adjusted timely, the thermal safety of battery can inevitable not can solve.
In view of above drawback, be necessary to provide a kind of internal temperature test structure of lithium ion battery to overcome above-mentioned defect in fact.
[utility model content]
The purpose of this utility model is to provide a kind of internal temperature test structure of lithium ion battery, and it can Validity Test inside battery zones of different discharge and recharge the temperature conditions of different phase.
To achieve these goals, the utility model adopts following technical scheme: a kind of internal temperature test structure of lithium ion battery, its bag temperature-sensitive test paper, lug, positive plate, negative plate, described temperature-sensitive test paper and lug are all installed on the positive plate and negative plate surface of battery, and described temperature-sensitive test paper and battery anode slice, negative plate are installed together by the method for reeling.
As a kind of improvement of the internal temperature test structure of a kind of lithium ion battery of the utility model, the good elastic membrane sealing of thermal conductivity for described temperature-sensitive test paper.
As a kind of improvement of the internal temperature test structure of a kind of lithium ion battery of the utility model, described temperature-sensitive test paper is installed on the some diverse locations between battery anode slice, negative plate.
When needing the internal temperature under regulation charge-discharge magnification of test battery, first the temperature-sensitive test paper by elastic membrane sealing is placed on and on battery anode slice, negative plate, needs the diverse location measured, and together with positive plate, negative plate with conventional barrier film reel, enter shell, dry, fluid injection, etc. series of processes until make finished product battery.The multiplying power of then this battery being planned discharges and recharges, and finishes rear dissection battery, takes out temperature-sensitive test paper, the temperature of reading inside battery each several part under the charge status of regulation multiplying power according to the temperature shown in temperature-sensitive test paper.
The beneficial effects of the utility model are: the some zoness of different that the temperature-sensitive test paper by elastic membrane sealing are placed on to battery anode slice, negative plate, by normal process, produce battery again, after completing, this battery being carried out to predetermined multiplying power discharges and recharges, after finishing, dissect battery, just can directly according to the variation of temperature-sensitive test paper color, read the temperature of inside battery zones of different under predetermined rate charge-discharge, this feasible, test simple in structure accurately.
[accompanying drawing explanation]
Fig. 1 is the positive plate installation diagram of the internal temperature test structure of a kind of lithium ion battery of the utility model;
Fig. 2 is the negative plate installation diagram of the internal temperature test structure of a kind of lithium ion battery of the utility model;
Fig. 3 is the electric core winding diagram of the internal temperature test structure of a kind of lithium ion battery of the utility model.
[embodiment]
Please refer to shown in Fig. 1 to Fig. 3, below in conjunction with case study on implementation, the utility model is described in further detail.
After some temperature-sensitive test paper 5 use elastic membrane sealings well, by the target area of required probe temperature, be placed on respectively positive plate 1 and surperficial upper and lug 6 sides of negative plate 2, again barrier film 3 is reeled together with positive plate 1, negative plate 2, put into battery case 4, and enter the follow-up battery production flow processs such as fluid injection, sealing.Until whole battery after explained hereafter completes routinely, by predetermined multiplying power, battery is discharged and recharged, after finishing, dissect battery, take out temperature-sensitive test paper 5, just can draw according to the change color on temperature-sensitive test paper 5 the different local temperature of inside battery under this rate charge-discharge.
Its operation principle is: the some zoness of different that the temperature-sensitive test paper by elastic membrane sealing are placed on to battery anode slice, negative plate, by normal process, produce battery again, after completing, this battery being carried out to predetermined multiplying power discharges and recharges, after finishing, dissect battery, just can directly according to the temperature shown in temperature-sensitive test paper, read the temperature of inside battery zones of different under predetermined rate charge-discharge.
The internal temperature test structure of a kind of lithium ion battery of the utility model, be not restricted to described in specification and execution mode, therefore for the personnel of familiar field, can easily realize additional advantage and modification, therefore in the situation that do not deviate from the spirit and scope of the universal that claim and equivalency range limit, the utility model is not limited to specific details, representational equipment and illustrates here and the examples shown of describing.
