Description
Technical field
The present invention relates to battery preparation technology field, more particularly to a kind of cylindrical battery of disjunctor.
Background technology
Cylindrical battery middle-size and small-size at present, for its internal structure, both positive and negative polarity distance is consistent and spacing is small, internal
Polarization is few, so the cycle life and uniformity of battery are all very good, it is also to produce dynamicization degree highest battery manufacture at present
Method, low production cost, the Tesla for having wide development space, the U.S. is used in cylindrical battery above electric automobile, achieves
Compared with ten-strike, in security control, heat management aspect is better than other shapes of battery to cylindrical battery, but is presently used on electric automobile
Cylindrical battery is majority with 18650,21700, also there is a small amount of 26800 battery, if diameter is excessive, internal heat dissipating is more difficult,
So as to influence cycle life, security performance and other various performances of battery, but diameter is too small, and battery capacity is small, in battery pack
The quantity of batteries in parallel connection is excessive during conjunction, welding difficulty increase, reliability reduction, so the feelings that can not increase in cylindrical battery diameter
Under condition, improve capacity and have very important significance.
The content of the invention
The invention solves the problems that the problem that above-mentioned prior art is present, there is provided a kind of cylindrical battery of disjunctor, cylinder is improved
The automaticity of type battery manufacture, reduces heating during discharge and recharge, improves security performance, is conducive to improving the property of assembled battery
Energy.
The present invention solves the technical scheme that its technical problem is used：The cylindrical battery of this disjunctor, including battery container,
Battery container is connected in parallel integrally including several Cylinder Shells, is interconnected and equipped with electrolyte between cylindrical shell,
Core is respectively provided with inside each cylindrical shell, the positive plate of core is connected with each self-corresponding cylindrical shell bottom respectively, rolled up
The negative plate of core is emitted with lid and is connected, and lid is emitted and is installed on metal connecting sheet by insulated enclosure circle, and metal connecting sheet sealing is installed
On Cylinder Shell, connection is integrated between adjacent metal connecting sheet, each lid emits and is located at each Cylinder Shell respectively
Center, adjacent cover is connected with conductive metal band between emitting, conductive metal band is externally provided with insulating barrier, the core inside cylindrical shell
In parallel connection.The structure can improve the automaticity of cylindrical battery manufacture, reduce cell in assembled battery
Connection number, and heating when reducing discharge and recharge, due to electrolyte inside UNICOM, it is possible to reduce each core in disjunctor battery
Coherence request, is conducive to improving the performance of assembled battery, cycle life and power-performance is improved, due to electrolyte inside and volume
The quantity of core increases, i.e., amount of substance increases, and internal space also increases, if a core short circuit, temperature will not rise it is too high,
Air pressure will not also be significantly increased, and cause the possibility of blast to reduce, so it is also the security performance for improving cylindrical battery
Manufacture method.
In order to further perfect, the number of Cylinder Shell is 2 to 8.
Further perfect, Cylinder Shell external diameter is 50mm-150mm for the height of 14mm-32mm Cylinder Shells.
Further perfect, the anode ear number that each core is drawn is 1 or 2, and negative electrode lug number is 1 or 2.
Further perfect, cylindrical shell is aluminum hull.
Further perfect, metal connecting sheet is aluminum metal film.
Further perfect, conductive metal band is nickel strap or steel band.
The invention has the advantages that：Electrolyte is connection in disjunctor battery of the present invention, and the core outermost of monomer is same
It is negative or positive electrode, can touches together, the cylindrical battery lug of such disjunctor can be welded disposably respectively, disposable laser envelope
Mouthful, improve automaticity, if a monomer of inside be short-circuited, after battery disjunctor, inner space slightly has increase, interior
The electrolyte and core in portion increase, i.e., inner material increases, a core short circuit, temperature and air pressure will not be made to increase very high, together
Sample lid emits increasing number, and also reducing lid and emitting to fail causes the possibility of blast, so the possibility of battery explosion is greatly decreased,
When carrying out battery combination, the connector and contact resistance of both positive and negative polarity can be greatly decreased, reduce the heating of battery pack, 2-8 even
The cell of body can be as a battery, during such battery combination, and the number of cell is reduced, and also reduces assembled battery
Battery consistency is depended on unduly, so as to greatly improve the life-span of assembled battery.
