Technical field
The utility model relates to the lithium ion battery field, relates in particular to a kind of multipole post battery cap that is suitable for the multi-pole lug lithium ion battery welding.
Background technology
Characteristics such as lithium ion battery is little because of its volume, energy density is high, memoryless, pollution-free are widely used in fields such as portable electric appts, electric tool, electric automobile, energy storage.Usually lithium ion battery is made up of several parts such as external cell housing, utmost point group, electrolyte and battery caps.The structure member of battery is that structure and the character of the key factor that influences battery performance, particularly battery cap makes a big impact to sealing, internal resistance and the fail safe of battery.Lithium ion battery cover is made up of parts such as cover plate, lug solder terminal, pad, burst disk, and lithium ion battery cover commonly used at present has only single pole, is difficult to satisfy some specific demand.
The utility model content
The purpose of the utility model provides the battery cap that is suitable for multipole ear and the use of partitioned organization lithium ion battery that a kind of sealing is good, insulating properties is good, and battery cap can be that circle also can be square.
A kind of lithium ion battery is with multipole post battery cap, comprise cover plate and fixing on the cover board and with the positive terminal and/or the negative terminal of cover plate mutually insulated, described positive terminal or negative terminal are at least two, and mutually insulated between each pole.
Can only be provided with positive terminal on the cover plate, or only be provided with negative terminal, also can be provided with positive terminal and negative terminal simultaneously.
When only being provided with positive terminal, positive terminal is at least two;
When only being provided with negative terminal, negative terminal is at least two;
When being provided with positive terminal and negative terminal simultaneously, and do not require that positive terminal and negative terminal all are at least two, so long as positive terminal is at least two, perhaps negative terminal be at least two all passable.
Described cover plate is a disc, and its central area is provided with burst disk.All poles evenly distribute on the circumferencial direction of cover plate.
Described cover plate can also be a rectangle, and all poles can be the matrix form arrangements or be " one " word arrangement that cover plate is provided with burst disk.
Described pole runs through cover plate, isolates each other through insulation spacer in the contact site of pole and cover plate and seals.
Pole can adopt the metal rivet that the conductivity that runs through cover plate is good, be easy to weld; Aluminium rivet for example; Behind the pole installation forming; Two terminations of pole have bulge, are provided with the Upper gasket of electric conducting material between the bulge on pole top and the cover plate end face, and an end of this Upper gasket is bent to form the afterbody that is used to connect external circuit.
Described afterbody is perpendicular to the end face of cover plate.
Be provided with lower gasket between the bulge of pole bottom and the cover plate bottom surface.
Upper and lower pad can adopt steel matter or steel nickel plating material that certain mechanical strength is arranged.Upper gasket has leader (afterbody) and is bent into can be convenient to external circuit with the vertical angle of cover plate and be connected.
Be structure as a whole with the corresponding insulation spacer of each pole.Insulation spacer can generally can adopt corrosion-resistant, resilient macromolecular material through the method moulding of injection moulding between pole and cover plate, both guaranteed the insulating properties between pole and cover plate and the pole, can guarantee the sealing at pole place again.
Described positive terminal and negative terminal are 2～10.Concrete quantity can be decided according to the quantity of battery utmost point group middle rank ear.
The utility model lithium ion battery is with the advantage of multipole post battery cap; A plurality of poles distribute on same cover plate; Be suitable for the welding of multipole ear,, be convenient to the reaction of inside battery diverse location is monitored and analyzed the pole piece of inside battery diverse location guiding external circuit.The partition management that also is suitable for high capacity cell internal capacity unit, the fail safe that improves high capacity cell is widely used in simulated battery and the high capacity lithium ion battery of partition type of the multipole ear of electrochemical research.
