Abstract
The utility model discloses a glass insulator for lithium manganese cells. The glass insulator comprises a glass body, a welding piece or an upper cover and a tantalum needle. The glass insulator also comprises an anticorrosion coating. The glass insulator has simple process and low cost. The glass insulator which prolongs the storage life of the cell and overcomes the problems of leakage and failure of the cell is suitable for the production of CR17335, CR17450, CR17505, CR26500 and CR34615 lithium/manganese cells.
Description
Affiliated technical field
The utility model relates to a kind of column type lithium cell, and especially the assembly of lithium-manganese cell belongs to technical field of chemical power.
Background technology
At present, in the load module of the hermetically sealed lithium of pillar/manganese dioxide series battery, all adopt glass insulator as insulator between loam cake that connects with negative pole and the tantalum pin that connects with positive pole, because its vitreum contacts with organic electrolyte in the battery, during long term storage, be subjected to the corrosion of electrolyte, make its decreasing insulating, and generation battery micro-short circuit phenomenon, cause battery generation self discharge, and open circuit voltage, load voltage and the capacity of its battery are descended, the storage life of battery shortens, and can leakage take place during seriously corroded and battery was lost efficacy in advance.
The utility model content
In order to overcome the corrosion proof deficiency of existing lithium-manganese cell glass insulator, the utility model provides a kind of corrosion resistant lithium-manganese cell glass insulator.
The technical scheme that its technical problem that solves the utility model adopts is: the lithium-manganese cell glass insulator, comprise vitreum, weldment or loam cake and tantalum pin, and Vitrea bottom is provided with anticorrosive coat.
Be provided with an anticorrosive coat at the position that vitreum contacts with electrolyte, stoped electrolyte Vitrea direct corrosion.
The beneficial effects of the utility model are that technology is simple, and is with low cost; Prolonged the storage life of battery, solved the leakage of lithium-manganese cell and shifted to an earlier date Problem of Failure.
Description of drawings
Fig. 1 is the split type superstructure of the utility model (execution mode an one) structural representation;
Fig. 2 is the utility model integral type superstructure (execution mode two) structural representation.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Execution mode one:
The lithium-manganese cell glass insulator comprises vitreum 1, weldment 2 and tantalum pin 3, and the bottom of vitreum 1 is provided with anticorrosive coat 4.
As Fig. 1, glass insulator and loam cake 5 are split-type structural.Weldment 2 welding with loam cake 5 and glass insulator constitute cover assembly.Below vitreum 1, apply the thick organosilicon dope 4 of the about 0.8mm of one deck greater than its area portions, put into temperature and be 80～100 ℃ constant temperature oven, time is 30～45 minutes, it is curable in the bottom of vitreum 1 to take out back organosilicon dope 4, and it is standby that cover assembly promptly can be used for assemble.Can be used for the production of CR17335, CR17505, CR26500, CR34615 type lithium/manganese dioxide battery.
Execution mode two:
The lithium-manganese cell glass insulator comprises vitreum 1, loam cake 5 and tantalum pin 3, and Vitrea bottom is provided with anticorrosive coat 4.
As Fig. 2, glass insulator and loam cake 5 are integral structure, constitute the integral type cover assembly.Below its vitreum 1, apply the thick organosilicon dope 4 of one deck 0.8mm greater than its area portions, put into temperature and be 80～100 ℃ constant temperature oven, time is 30～45 minutes, take out back organosilicon dope and can 4 be solidificated in the bottom of vitreum 1, it is standby that cover assembly promptly can be used for assemble.Can be used for the production of CR17335, CR17450, CR17505, CR26500, CR34615 type lithium/manganese dioxide battery.
Can draw following result through experiment, whether electrical property and the battery glass insulator of battery in the long term storage process scribbles dope very big difference is arranged.As not being coated with dope, the vitreum on the insulator is caused the insulation resistance of insulator to descend, thereby causes the both positive and negative polarity of battery to produce little electric current self discharge by insulator by the attenuation of electrolyte burn into vitreum thickness, and period of storage is less than 3 years.A kind of organosilicon dope of coating on the vitreum of insulator, electrolyte can be reduced Vitrea corrosion or isolates, keep vitreum flat appearance light, make the storage time limit of battery extend to 5～8 years, can not produce bigger self-discharge phenomenon by insulator.
In conjunction with the accompanying drawings embodiment of the present utility model has been carried out exemplary description above, obviously the utility model is not limited thereto, and the various remodeling that carry out in the utility model scope all do not exceed protection range of the present utility model.
