Abstract
The invention relates to a Li battery preparing method, pasting an adhesive tape on a Li tape as cathode, and then preparing the finished Li battery product by normal producing processes, where the adhesive tape can be of polyamine, polyethylene or other inert material and can be a stripe in shape or of other geometrical shape, and the number of adhesive tapes can be one or plural; the discharge consistency of the prepared Li battery has a larger improvement and simultaneously the process is simple and the production cost is low. And the Li utilization ratio can be increased by about 10%.
Description
Technical field:
The present invention relates to the preparation method of lithium battery.
Background technology:
In the production of existing lithium primary battery, generally metal lithium bands as battery cathode, the battery of Sheng Chaning has usually been found to occur in the battery discharge procedure lithium band and has been ruptured between therefrom like this, thereby causes occurring the phenomenon that a large amount of lithium metals can not complete reaction.Therefore the battery of producing always has a certain proportion of discharge capacity of the cell lower.
Summary of the invention:
The purpose of this utility model is: a kind of method that improves lithium battery lithium metal utilance is provided.
Using metal lithium bands to paste an adhesive tape on as the metal lithium bands of battery cathode, prepare the lithium battery finished product by normal production programme more afterwards.
The adhesive tape material can be polyamide or polyethylene or other inert material.
Adhesive tape can be bar shaped, also can be other geometry.
Adhesive tape can be one, also can be many.
The consistency of battery discharge improves a lot behind use the present invention, technology is simple simultaneously, production cost is low, synergy is obvious, can also prevent the phenomenon of lithium battery discharge later stage lithium sheet fracture, it is about 10% that the battery average size improves, and that is to say that the utilance of lithium metal in the lithium battery can improve about 10%.
Description of drawings:
Accompanying drawing 1 is that the master that the lithium band adds adhesive tape in the embodiment of the invention looks schematic diagram;
Accompanying drawing 2 is lithium battery discharge curves of the embodiment of the invention;
Accompanying drawing 3 is not use lithium battery discharge curve of the present invention.
Execution mode:
As Fig. 1: stick the adhesive tape (2) of the wide 2mm of one deck, thick 0.02mm in negative electrode lithium band (1) center of CR123A battery, adhesive tape (2) material can be polyamide or polyethylene or other inert material.And then lithium band (1) is used for producing.The battery that such lithium band (1) is produced is when discharge, because lithium band (1) center has sub-fraction lithium band (1) to be covered by adhesive tape (2), can not regular picture, therefore lithium band (1) hits exactly and still has very little a part of lithium band (1) unreacted to finish when battery discharge finishes, has so just played the effect of Ampereconductors.
Fig. 2, Fig. 3 add adhesive tape (2) and the lithium battery discharge curve comparison diagram that does not add adhesive tape (2) on negative electrode lithium band (1), this shows its distinct effect in front and back, the method can also prevent the phenomenon of lithium battery discharge later stage lithium sheet fracture simultaneously, thereby has improved the utilance of lithium metal.
Claims (4)
1, a kind of method that improves lithium battery lithium metal utilance is characterized in that: using metal lithium bands to paste an adhesive tape on as the metal lithium bands of battery cathode, prepare the lithium battery finished product by normal production programme more afterwards.
2, a kind of method that improves lithium battery lithium metal utilance as claimed in claim 1 is characterized in that: the adhesive tape material can be polyamide or polyethylene or other inert material.
3, a kind of method that improves lithium battery lithium metal utilance as claimed in claim 1, it is characterized in that: adhesive tape can be bar shaped, also can be other geometry.
4, a kind of method that improves lithium battery lithium metal utilance as claimed in claim 1, it is characterized in that: adhesive tape can be one, also can be many.
