Abstract
The utility model relates to a soft packaging lithium ion battery polar ear with a short circuit protecting function, which comprises a conducting bar, hot melt material and PTC, wherein the conducting bar is arranged outside the hot melt material which is directly compounded to a switching off position of the PTC; the hot melt material is any one or more than two compounds of modified polypropylene, modified polyethylene, vinyl acetate, a terpene compound, rosin and paraffin wax. Because the melt material is directly compounded to the switching off position of the PTC, when a battery occurs an external short circuit, the PTC in the polar ear can switch off the output of the battery without occupying the inner space and the outer space of the battery to ensure the safety of the battery and convenient operation. The utility model can be used for various soft packaging lithium ion batteries.
Description
Technical field
The utility model belongs to the lithium ion battery structure technical field, particularly relates to a kind of soft package lithium ion cell polar ear with short-circuit protection function.
Background technology
Present known battery is made up of metal conductive strips and hot melt material with lug, and itself does not possess the short-circuit protection function to battery.The external short-circuit protection function device of battery can be realized protection, but will take the space outerpace of battery, and operation inconvenience.Chinese patent application number is that 03223363.9 safety-type polymer secondary lithium battery discloses the inside that PTC is positioned at lithium ion battery, and one lead-in wire directly or by lead is connected with the collector of the moon/anode of battery, and another goes between and draws with battery external that lead is connected or the direct lead of drawing as battery.Though this patent has played short-circuit protection function, taken the inner space of battery, and operation inconvenience.
The utility model content
The utility model provides a kind of saving battery interior or exterior space for solving the problem that exists in the known technology, and the easy to operate soft package lithium ion cell polar ear with short-circuit protection function.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Soft package lithium ion cell polar ear with short-circuit protection function comprises bus, hot melt material and PTC, is characterized in: described bus is located at the outside of described hot melt material, and described hot melt material directly is compound on the shutoff position of described PTC.
The utility model can also adopt following technical measures to realize:
Have the soft package lithium ion cell polar ear of short-circuit protection function, be characterized in: described hot melt material is any or the wherein two or more compound in modified polypropene, modified poly ethylene, vinylacetate, terpene compound, rosin, the paraffin.
Have the soft package lithium ion cell polar ear of short-circuit protection function, be characterized in: described bus material be in gold, silver, copper, aluminium, the nickel metal material any.
Have the soft package lithium ion cell polar ear of short-circuit protection function, be characterized in: described bus material is a material with carbon element.
Have the soft package lithium ion cell polar ear of short-circuit protection function, be characterized in: described bus material is a conducting polymer materials.
Advantage and the good effect that the utlity model has are: because hot melt material is compound on the shutoff position of PTC, the PTC of lug inside can turn-off and not take space, battery inside and outside with the output of battery when battery generation external short circuit, guaranteed the fail safe of battery, and easy to operate.
Description of drawings
Fig. 1 is the structural representation that the utlity model has the soft package lithium ion cell polar ear of short-circuit protection function.
Label among the figure is respectively: the 1-bus, and the 2-hot melt material, the 3-bus, 4-PTC turn-offs the position.
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: see also Fig. 1, hot melt material 2 directly is compound on the shutoff position 4 of PTC, bus 1,3 is stayed the outside of hot melt material 2.Hot melt material 2 can be any one or two kinds of above compounds in modified polypropene, modified poly ethylene, vinylacetate, terpene compound, rosin, the paraffin.
Operating principle of the present utility model is that the PTC of lug inside can turn-off the output of battery when battery generation external short circuit, because PTC is in lug inside, so do not take space, battery inside and outside and easy to operate.
Claims (5)
