Abstract
The utility model provides an assembled battery with a plurality of wound cells, which comprises electrodes and electrolyte. The assembled battery is characterized by further including a battery wound cell support and a battery outer casing, a battery wound cell containing portion is arranged inside the battery wound cell support adopting a honeycomb structure, electrode holes, a liquid filling hole and a pressure relief valve are arranged on the battery outer casing, and the electrodes penetrates through the electrode holes. The assembled battery with a plurality of wound cells can structurally support large-ratio discharging of the battery cells and is particularly suitable for use as a high-power battery. Additionally, the wound cells can be arranged inside the assembled battery with a plurality of wound cells, thereby a single battery with large capacity can be prepared.
Description
Technical field
The utility model relates to battery, especially lithium rechargeable battery.
Background technology
Electrokinetic cell refers generally to have the battery of higher capacity and certain output power density, and the driving power and the hybrid power power supply class battery that can be used as means of transportations such as motor vehicle use.The part electrokinetic cell also can be used as energy storage battery usually through design improvement, comprises the variable load accumulated cell apparatus of electrical network.Also can be used as the stand-by power supply of operating office etc. in addition.
In recent years, lithium rechargeable battery has represented the rosy prospect as the electrokinetic cell in future.The preparation of cylinder type lithium ion secondary battery has wherein had the technology of comparative maturity at present.But, the cylinder type lithium ion secondary battery that uses as power battery pack, in the electrode lead-out mode more common a kind of be on positive/negative plate, to weld a lug respectively, lug links to each other with external electrode more then, therefore, when electric current flows out battery internal resistance higher, the specific power of battery is less than normal.
The utility model content
As mentioned above, the tradition monovolume uses spot-welding technology around electric core battery often lug being welded to the battery external electrode, and this spot-welding technology makes monovolume around the lug of electric core with the joint face between the electrode is little, resistance big and be difficult to guarantee the hundred-percent power that is welded into.
For solving the problems of the technologies described above, the utility model provides a kind of multireel core assembled battery, and it comprises electrode, electrolyte, it is characterized in that, also comprises: the battery roll core support, adopt cellular structure, in establish the battery roll core accommodation section; Battery case has electrode hole, liquid injection hole, relief valve on the battery case, electrode passes from described electrode hole.
Above-mentioned battery roll core accommodation section is the through hole that diameter is not less than the battery roll core diameter.
Also be provided with the fire retardant filler opening on the above-mentioned battery roll core support.Described fire retardant filler opening is and the same hole radially of the through hole that holds battery roll core.
Above-mentioned battery also comprises collector, and described battery roll core is electrically connected.Collector also connects external electrode simultaneously.
Be electrically connected the solder technology that can adopt routine between the multireel core assembled battery that the utility model provides, volume core lug and lug or collector, and avoid adopting traditional monovolume around the employed spot-welding technology of electric core battery.Therefore, the multireel core assembled battery structure that the utility model provides can be supported the big multiplying power discharging of electric core, is particularly suitable for doing high-power battery and uses.
In addition, the multireel core assembled battery that the utility model provides can built-in a plurality of volume cores, therefore can prepare jumbo cell.
If the battery roll core support is provided with the fire retardant filler opening, built-in fire retardant can be effectively fire-retardant when battery such as blasts at security incident, avoids the generation of bigger security incident.

Embodiment
Below with reference to above-mentioned accompanying drawing, embodiment of the present utility model is elaborated.
Battery roll core support 1 shown in accompanying drawing 1,2 comprises the through hole 2 that holds battery roll core, and and through hole 2 same fire retardant accommodation holes 3 radially.
Accompanying drawing 3 is the battery roll core support of the battery roll core 4 of having packed into.
Accompanying drawing 4 is for having installed the battery roll core support of collector 5.Described collector 5 has also connected electrode 6.
The battery roll core support pack into battery roll core, install in the battery case 7 of inserting again behind the collector as shown in Figure 5, promptly be assembled into multireel core assembled battery as shown in Figure 6.Electrode hole 8, liquid injection hole 9, relief valve 10 are arranged on the battery case, and electrode 68 passes from described electrode hole.
Devices such as the liquid injection hole that needs to use in the utility model, relief valve all can adopt commercialization or the public design of knowing.
It should be noted that; any tangible displacement and conversion to components and parts related in the scheme required for protection in the utility model and scheme all should be treated as disclosed or be included within the claimed scope of the utility model by the utility model.
