Technical field
The present invention relates to technical field of lithium batteries, the lithium battery structure that particularly has lead-out wire improves.
Background technology
Have the class that lead-out wire formula lithium battery is a lithium battery, so lithium/thinly chloride battery also comprises the structure of lead-out wire formula.Lithium/thinly chloride battery is that negative pole, thionyl chloride are positive active material and electrolyte with the lithium metal, is the lithium battery of reaction carriers with carbon.Accompanying drawing the 1, the 2nd, the basic structure of existing lithium/thinly chloride battery.It comprises battery container 1 and is sleeved on battery container interior lithium sheet 2, limit film 3, carbon bag 4 successively.Be provided with epiphragma 5 at the Kou Yanchu of battery container 1, epiphragma is provided with cap assembly.Cap assembly comprises block body 6, is arranged on seal 7 and anodal deriving structure on the block body.Anodal deriving structure comprises collector 8 parts lead-out wire 11 parts of inserting in the anodal carbon bag outer with extending to battery container.Realize insulation by glass capsulation 10 between anodal deriving structure and the block body 6.
Hermetic unit in above-mentioned its anodal deriving structure of this class lithium battery and collector 8 parts and the lead-out wire 11 that extends to outside the battery container are integrative-structures, and there are many defectives in the anodal deriving structure of this integral type:
When 1, producing, after cap assembly is made, then to form the lithium battery semi-finished product to the carbon bag that the collector in the cap assembly partly inserts in the battery container, need then to be immersed in the electrolyte, in battery, inject electrolyte making lithium battery semi-finished product integral body.Owing to be that cell integrated immersion comes fluid injection, can cause lead-out wire 11 partial oxidations and the difficult tin of going up.For this reason, need manually clean or strike off the oxide layer on the lead-out wire, make the production process complexity, manufacturing cost height, and the hidden danger of short circuit when existing operation.
2, owing to the anodal deriving structure of existing this integral type, lead-out wire is long to be extended in outside the battery container, deposits, transports and add to bend easily man-hour, be out of shape, and might make that also the glass capsulation place is loosening or produce damage, causes battery hermetization bad.
3 moreover the anodal deriving structure of the integral type made of this employing commaterial, be difficult to make simultaneously collector partly to have good catchment effect, good sealing property is arranged and can make lead-out wire that tin performance in the good welding is arranged with the glass capsulation place.
Summary of the invention
Technical problem to be solved by this invention provides a kind of lead-type anode post lithium battery that can have tin performance in good catchment effect, excellent sealing performance and the good welding simultaneously.
For solving the problems of the technologies described above, a kind of lead-type anode post lithium battery of the present invention, comprise battery container, be set with the lithium sheet in the battery container successively, the limit film, the carbon bag, the Kou Yanchu of described battery container is provided with epiphragma, epiphragma is provided with the block body, be connected with anodal deriving structure on the block body, this positive pole deriving structure has comprised the collector of afflux effect, positive terminal, lead-out wire, described collector, positive terminal and lead-out wire are parts independently separately, positive terminal one end joins with the collector that is positioned at battery container, and the block body that the other end is welded on the battery container is connected with lead-out wire.
The positive terminal of anodal deriving structure is the T font, and positive terminal upper end major part fits tightly with the lead-out wire that is inverted T-shaped and links into an integrated entity by welding manner, and positive terminal lower end microcephaly and collector upper end fit tightly and link into an integrated entity.The collector main body is J-shaped, is inverted assembling, and collector upper end crotch and positive terminal lower end weld together, and collector lower end cross section is middle word shape.
The collector of anodal deriving structure can have multiple structure type in the technical solution of the present invention, and the collector main body is 1 font, and the collector upper end welds together with the positive terminal lower end, and collector lower end cross section is middle word shape; Collector can also be that main body is zigzag, and the collector upper end welds together with the positive terminal lower end, and collector lower end cross section is middle word shape.
The technique scheme collector can the choice set fluidity can be made by good pure nickel and alloy thereof, and positive terminal adopts the 4J28 alloy to make, and lead-out wire is selected strong zinc-plated, the gold-plated or silver-plated coating alloy of tin ability etc. for use, and this lead-out wire good toughness is frangibility not also.
The present invention has following remarkable result compared to existing technology:
Lead-type anode post lithium battery of the present invention, its be positioned at inside battery collector, to extend to this external positive terminal of battery cap and lead-out wire be parts independently separately, can select for use the material of corresponding best performance to make.And the anodal deriving structure of integral type can only adopt a kind of material to make.The material of the anodal deriving structure of existing processing mainly is the 4J28 alloy, although this material has good sealing property with glass, its catchment effect is just poor, and supreme tin ability, also flexible simultaneously frangibility; And adopt the anodal deriving structure that the unified FeNi50 of employing alloy is processed into to exist tin not strong, the defective that sealing property is not strong.
The split type anodal deriving structure that the present invention proposes, collector can be made by good nickel and nickel alloy by the choice set fluidity, be processed into flat-shaped structure simultaneously, not only increase the electric current fan-out capability of battery, but also occur buckling phenomenon can avoid collector to insert the carbon bag time.Positive terminal adopts the 4J28 can be better and glass capsulation, and lead-out wire is then conveniently selected the strong zinc-plated alloy of tin ability for use, and this lead-out wire good toughness is frangibility not also.This split-type structural can make collector partly have good catchment effect, good sealing property be arranged and can make lead-out wire that tin performance in the good welding is arranged with the glass capsulation place simultaneously.
