Abstract
The utility model discloses a kind of soft-package battery aluminium-to-nickel band glue lug sheet, belong to technical field of lithium ion.The utility model adopts following technical scheme to realize: lug body is stacked respective one end by aluminium flake, nickel sheet and forms, PTC is established between the contact-making surface of aluminium flake and nickel sheet, aluminium flake and nickel sheet lamination contact position wrap insulate layer, be stained with epoxy resin board and aluminium flake and nickel sheet be fixed as one outside insulating barrier.Epoxy resin board fixes aluminium flake and nickel sheet, prevents double layer of metal sheet and the stressed disengaging of PTC.Establish PTC in the middle of aluminium flake and nickel sheet, during soft-package battery discharge and recharge, electric current can pass through PTC part, and PTC is a kind of semiconductor resistor of temperature sensitivity, when exceeding certain temperature (Curie temperature), its resistance value along with the rising of temperature be increasing of step evolution.When battery runs into overcurrent, problems of excessive heat, the PTC on lug can play and avoid overcurrent and overheated effect, improves stability and the security performance of soft-package battery.
Description
Technical field
The utility model discloses a kind of soft-package battery aluminium-to-nickel band glue lug sheet, belong to technical field of lithium ion.
Background technology
Soft-package battery energy density is large, and production efficiency is high, and cost is low, and especially connection in series-parallel combination solder joint is few, and security performance is relative with stability better, is more and more widely used.Along with the expansion of lithium ion battery applications scope, people propose higher requirement to lithium ion battery, the especially guarantee of security performance aspect.Soft-package battery is in charge and discharge process, if in the situations such as inner sudden short circuit, lug place there will be overcurrent or overheated, and battery is damaged, and even produces potential safety hazard.Soft-package battery positive pole ear adopts aluminium-to-nickel band glue lug usually, and namely aluminium flake is by ultrasonic wave or be laser-welded in nickel sheet, and object is the ultra-sonic welded connection in series-parallel combination of soft-package battery of being more convenient for.If overcurrent protective device can be increased at soft-package battery anode ear aluminium-to-nickel place, stability and the security performance of battery just can be improved.
Summary of the invention
For the problems referred to above, the utility model provides a kind of soft-package battery aluminium-to-nickel band glue lug sheet, solves stability and the safety high of soft-package battery.
To achieve these goals, the utility model adopts following technical scheme to realize:
Lug body is stacked respective one end by aluminium flake, nickel sheet and forms, and establishes PTC between the contact-making surface of aluminium flake and nickel sheet, and aluminium flake and nickel sheet lamination contact position wrap insulate layer, be stained with epoxy resin board and aluminium flake and nickel sheet be fixed as one outside insulating barrier.
As preferably, the insulating barrier of aluminium flake and nickel sheet lamination contact position parcel extends to the middle part of aluminium flake, and insulating barrier is PP glue.
Epoxy resin board fixes aluminium flake and nickel sheet, prevents double layer of metal sheet and the stressed disengaging of PTC.Establish PTC in the middle of aluminium flake and nickel sheet, during soft-package battery discharge and recharge, electric current can pass through PTC part, and PTC is a kind of semiconductor resistor of temperature sensitivity, when exceeding certain temperature (Curie temperature), its resistance value along with the rising of temperature be increasing of step evolution.When battery runs into overcurrent, problems of excessive heat, the PTC on lug can play and avoid overcurrent and overheated effect, improves stability and the security performance of soft-package battery.
Accompanying drawing explanation
Fig. 1 is the utility model floor map;
Fig. 2 is the utility model lug generalized section;
Wherein: 1, aluminium flake, 2, nickel sheet, 3, PTC, 4, insulating barrier, 5, epoxy resin plate.
Embodiment
Also by reference to the accompanying drawings the technical solution of the utility model is further described below by embodiment.
As depicted in figs. 1 and 2, soft-package battery aluminium-to-nickel band glue lug sheet, this soft-package battery aluminium-to-nickel band glue lug sheet is made up of aluminium flake 1, nickel sheet 2, PTC3, insulating barrier 4 and epoxy resin board 5 five part.PTC is positioned at metal aluminium flake and metal nickel sheet junction, and insulating barrier about 4 is two-layer encases part aluminium flake and whole aluminium and nickel sheet metal junction, and aluminium and nickel metal connecting sheet junction skin are stained with upper and lower two-layer epoxy resin board.The connection of epoxy resin board fixing metal aluminium flake and metal nickel sheet, prevents double layer of metal sheet and the stressed disengaging of PTC.Insulating barrier selects PP glue.
Be provided with PTC in the middle of aluminium flake and nickel sheet, during soft-package battery discharge and recharge, electric current can pass through PTC part, and PTC can, temperature excessive at current surge shield to circuit time too high.During use, be connected in series in circuit, under normal circumstances, its resistance is very little, and loss is also very little, does not affect circuit and normally works; If but having overcurrent (as short circuit) to occur, its temperature raises, and its resistance sharply raises thereupon, reaches the effect of Limited Current, avoids damaging the components and parts in circuit.When after failture evacuation, the temperature of PTC device declines automatically, returns to low resistive state again, plays overcurrent, superheat protecting function, improves stability and the security performance of soft-package battery.
