Abstract
The invention is concerned with the soft packing battery pole ear structure, includes the aluminum strip, the characteristic is: folds the aluminum strip end and the non-aluminum strip end as whole, composites the thermal material at the folding point. The aluminum is the inner connection that can not erode, the non-aluminum strip, namely copper strip, nickel strip and stainless steel strip, is outer connection, that is not easy to break and easy to connect with outer line, is simple structure and with higher reliability.
Description
Technical field
The invention belongs to the lithium ion battery structure technical field, particularly relate to a kind of extreme ear structure of flexible-packed battery.
Background technology
The positive pole ear of flexible-packed batteries such as present known polymer battery is generally fine aluminium bar lug, and this fine aluminium bar lug itself fractures easily and is not easy and is connected with outer circuit, influences final battery quality.
Summary of the invention
The present invention provides a kind of simple in structure for solving problems of the prior art, and is solid and reliable, is not easy the extreme ear structure of flexible-packed battery that fractures and be connected with outer circuit easily.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: extreme ear structure of flexible-packed battery, comprise aluminum strip, be characterized in: described aluminum strip one end and non-aluminum metal bar one endlap are put, at stacked place composite hot melt material, described aluminum strip and described non-aluminum metal bar are connected as one.
The present invention can also adopt following technical measures to realize: described non-aluminum metal bar is copper bar or copper alloy bar or nickel bar or nickel alloy bar or stainless steel strip; Described hot melt material is any one or two kinds of above compounds in modified polypropene, modified poly ethylene, polyester, vinylacetate, terpene compound, rosin, the paraffin
The advantage that the present invention has with good effect is: because aluminum strip is connected as inside, corrosion phenomenon can not occur, non-aluminum metal bar such as copper bar, nickel bar, stainless steel strip connects outside, is not easy to fracture and is connected with outer circuit easily, and simple in structure, improved the reliability of final battery.
Description of drawings
Fig. 1 is a battery safety device against high-temperature and high-voltage structural representation of the present invention;
Label among the figure is respectively: 1, aluminum strip; 2, non-aluminum metal bar; 3, hot melt material.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
Embodiment 1:
See also Fig. 1, aluminum strip 1 one ends and non-aluminum metal bar 2 one endlaps are put form the composite metal bar together,, form compound lug at the outside of composite metal bar junction composite hot melt material 3.Non-aluminum metal bar can be copper bar, copper alloy bar, nickel bar, nickel alloy bar, stainless steel strip.Hot melt material can be one or more the compound in modified polypropene, modified poly ethylene, polyester, vinylacetate, terpene compound, rosin, the paraffin.
Operating principle of the present invention is, non-aluminum metal bars such as aluminum strip and copper bar, nickel bar, stainless steel strip formed the composite metal bar, at the outside, junction of composite metal bar composite hot melt glue material.Aluminum strip connects as inside, corrosion phenomenon can not occur, and non-aluminum metal bar such as copper bar, nickel bar, stainless steel strip connects outside, is not easy to fracture and is connected with outer circuit easily, has improved the reliability of final battery.
Claims (3)
