Common single lithium cell core comprises positive and negative plate and positive and negative lug, the electric weight of output is limited, mostly in 3V～12V left and right, only can power to small-sized electronic product, if will, for just not enough on the large product of the driving electric weight demands such as electric bicycle, now need a plurality of battery cores to combine.Lithium battery has fever phenomenon in charge and discharge process, and when one group of lithium battery generation amount of heat that goes wrong, heat passes to lithium battery around, causes more lithium battery to go wrong.
Granted publication number discloses a kind of support of lithium battery group for the patent documentation of CN202977562U, this support is arranged in consumer unit, support comprises a body, body adopts flame-retarded plastic to make, body has several evenly distributed mounting grooves, between adjacent two mounting grooves in left and right, be connected, between adjacent two mounting grooves in front and back, have cell wall, the bottom of each mounting groove has through hole.Granted publication number for the patent documentation of CN20503048U discloses a kind of cylindrical lithium battery support, comprising: support body, on support body, be provided with a plurality of battery core holders, and battery core holder is for being equally spaced.This cylindrical lithium battery support is shaped support, and its part is one-shot forming, and support adopts the one-shot forming of polypropylene flame redardant PP material.Above-mentioned two disclosed documents are fixed lithium battery by support, and make to keep between lithium battery certain gap, this contributes to heat radiation, and when going wrong, lithium battery is not easy to conduct heat to other lithium batteries, but between lithium battery, leaving space can cause space availability ratio not high, battery pack volume is larger, and this does not meet the trend of present miniaturization development.
Utility model content
The utility model, for the problems referred to above, has proposed the heat insulation storage battery of a kind of grouping simple in structure, safe and reliable, that space availability ratio is high.
The technical scheme that the utility model is taked is as follows:
The heat insulation storage battery that divides into groups, comprises some groups of cells, and each is organized cell and arranges successively, between adjacent set cell, is provided with thermal isolation film.
Because use thermal isolation film, each is organized between cell and can not conduct heat, and the generation amount of heat even if certain group cell goes wrong, can not exert an influence to the cell of adjacent groups yet; Use thermal isolation film can also make close contact between cell, improved space availability ratio, effectively reduced the volume of storage battery.
As preferably, described thermal isolation film is that thickness is the polyamide film of 0.2～0.5mm.Polyamide film has good heat-proof quality and resistance to elevated temperatures.The also resistant to elevated temperatures film of other materials simultaneously.
As preferably, described thermal isolation film for separately independently several, correspondingly between adjacent set cell arranges one.
More preferred, described thermal isolation film is one, and roundabout organizes between cell around the home at each.
As preferably, a side of described thermal isolation film is covered with viscous material layer.Viscous material layer can make thermal isolation film and cell fix, and difficult drop-off guarantees that with this effect of heat insulation of respectively organizing between cell is reliable.
More preferred, the both sides of described thermal isolation film are covered with viscous material layer.Thermal isolation film can also play the effect of auxiliary securing unit battery, makes respectively to organize cell and is closely adjacent to.
As preferably, every group of cell comprises 2～10 cells, and is yi word pattern and arranges.
As preferably, each quantity of organizing cell equates and relatively aligns.
As preferably, each end face of organizing cell is welded with respectively with bottom surface the nickel strap being connected for circuit.This nickel strap can be connected with each other the electrode of cell.
As preferably, each cell that belongs to a group together is parallel with one another, series connection successively between adjacent set.Parallel connection can provide larger electric current, and tandem energy provides larger voltage, by connection in series-parallel, arranges in pairs or groups, and can obtain suitable voltage.
The beneficial effects of the utility model are: by thermal isolation film, can make respectively to organize between cell and can not conduct heat, the generation amount of heat even if certain group cell goes wrong, can not exert an influence to the cell of adjacent groups yet; By thermal isolation film, can also make close contact between cell, improve space availability ratio, effectively reduce the volume of storage battery.

Embodiment
As shown in Figure 1, a kind of heat insulation storage battery that divides into groups, comprises some groups of cells 1, and each is organized cell and arranges successively, is provided with thermal isolation film 3 between adjacent set cell.Every group of cell comprises 5 cells that cathode and anode directions is consistent, and is yi word pattern and arranges, and each quantity of organizing cell equates and relatively align, and each end face of organizing cell is welded with respectively with bottom surface the nickel strap 2 being connected for circuit.Nickel strap 2 is rectangle, and two long limits of nickel strap are connected with the spot welding of two adjacent groups cell respectively.The long limit of nickel strap makes connection parallel with one another between this group cell; The cathode and anode directions of two groups of cells that connect with two long side welds of nickel strap is arranged contrary, and one is positive one negative, with this, realizes being connected in series of two groups of cells.Each nickel strap also comprises an outward extending brace 4, and brace, for the voltage of the every Battery pack of test monitoring, can be realized the power supply of multiple voltage pattern by the connected mode of nickel strap.
The top of cell and bottom are respectively equipped with a thin plate with viscous layer, by these two thin plates, assist securing unit battery, and rectangle nickel strap also can be to fixedly playing a role between cell.
As shown in Figure 2, the polyamide film that thermal isolation film 3 is 0.3mm for thickness, thermal isolation film is comprised of one deck thermal insulation layer 5 and one deck viscous material layer 6.Thermal isolation film can also be comprised of two layers of viscous material layer and one deck thermal insulation layer, and now thermal insulation layer is in the centre of two-layer cohesive material.Viscous material layer can make thermal isolation film and cell fix, and difficult drop-off guarantees that with this effect of heat insulation of respectively organizing between cell is reliable.Thermal isolation film can also be the resistant to elevated temperatures film of other materials.
The present embodiment thermal isolation film 3 is several polyamide films independently separately, correspondingly between adjacent set cell arranges one.As shown in Figure 3, thermal isolation film can also be a polyamide film, and roundabout organizes between cell around the home at each.Thermal isolation film makes respectively to organize between cell can not conduct heat, and the generation amount of heat even if certain group cell goes wrong, can not exert an influence to the cell of adjacent groups yet; Use thermal isolation film can also make close contact between cell, improved space availability ratio, effectively reduced the volume of storage battery.
