The rise of the concepts such as machine, the research of corresponding power supply device are also intimately got up.
Currently, the temporary unfolded battery in market, and only its performance of bent battery is also much not up to the expection of people,
Such as the solid state battery of Taiwan brightness energy, although can bend, multiplying power and cycle performance are lower；For another example Apple passes through
More batteries carry out in series and parallel, solving bending and the folding problem of battery, but baby battery preparation is difficult, high production cost, and
Battery consistency is required stringent；In addition to this, it is modified also by pole piece shape or structure, realizes the bendable of battery
Qu Xing；But the main body battery core of battery bending and folding property being not only forced in battery, but also by encapsulating material
It influences.
Therefore, it is necessary to seek the new technical solution of one kind to solve the above problems.
Summary of the invention
The purpose of this utility model is: providing a kind of battery with " flexible straw structure ".
In order to achieve the above purposes, the technical solution adopted by the utility model is:
One kind have " flexible straw structure " battery, this battery include folded package material and be located at fold
Battery core main body inside encapsulating material, the folded package material includes encapsulating material layer, and is located at encapsulating material layer surface
Flexible straw structural type groove, the groove be it is a plurality of, and be arranged in parallel between each other.
The encapsulating material layer is aluminum plastic film or PET film.
The groove is one such in triangular prism, quadrangular, pentagonal prism and hexagonal prisms on three-dimensional.
The groove is triangular in shape in the two-dimensional direction, rectangle, square, zigzag, waveform, trapezoidal and five sides
One of shape.
The edges and corners of the groove are chamfering.
Width between the groove is 1mm-20mm.
The battery core main body includes the electrode unit that one or more sequences stack, and the electrode unit includes in order
Positive plate, negative electrode tab and the electricity injected in the flexible insulating film and battery case among positive plate and negative electrode tab stacked
Solve liquid or gel electrolyte.
The flexible insulating film includes diaphragm and solid electrolyte membrane；The diaphragm is PP film, PE film, PP-PE film, nonwoven
Cloth, cellophane or the above-mentioned diaphragm after compound；The solid electrolyte membrane includes polymer-based solid state electrolyte
Film, inorganic solid electrolyte layer, Organic-inorganic composite electrolyte layer and above-mentioned solid electrolyte are combined with above-mentioned diaphragm
Flexible electrolyte film.
In the above-mentioned technical solutions, compared with prior art, achieved to have the technical effect that 1, " flexible straw
The foldable encapsulating material of structure " is by the machine preparation of punching hole, to realize the folding purpose of encapsulating material；2, above-mentioned foldable
After encapsulating material encapsulates battery, the bending performance and folding property of battery are all greatly improved；3, folded battery can answer
The products such as folding cell phone, preparation is simple, at low cost.

Fig. 3 is the structural schematic diagram that battery repeatedly folds.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments.
Embodiment one:
As described in Fig. 1 to 3, one kind of the utility model has the battery of " flexible straw structure ", this battery pack
Folded package material and the battery core main body positioned at folded package material internal are included, the folded package material includes encapsulating material
Layer, and positioned at the flexible straw structural type groove of encapsulating material layer surface, the groove is a plurality of, and between each other
It is arranged in parallel.
The encapsulating material layer is aluminum plastic film or PET film.
The groove is one such in triangular prism, quadrangular, pentagonal prism and hexagonal prisms on three-dimensional.
The groove is triangular in shape in the two-dimensional direction, rectangle, square, zigzag, waveform, trapezoidal and five sides
One of shape.
The edges and corners of the groove are chamfering.
Width between the groove is 1mm-20mm.
The battery core main body includes the electrode unit that one or more sequences stack, and the electrode unit includes in order
Positive plate, negative electrode tab and the electricity injected in the flexible insulating film and battery case among positive plate and negative electrode tab stacked
Solve liquid or gel electrolyte.
The flexible insulating film includes diaphragm and solid electrolyte membrane；The diaphragm is PP film, PE film, PP-PE film, nonwoven
Cloth, cellophane or the above-mentioned diaphragm after compound；The solid electrolyte membrane includes polymer-based solid state electrolyte
Film, inorganic solid electrolyte layer, Organic-inorganic composite electrolyte layer and above-mentioned solid electrolyte are combined with above-mentioned diaphragm
