Referring to fig. 1, a flexible solar cell module includes a plurality of cell units 100, the cell units 100 having flexibility and having a bent middle portion, the plurality of cell units 100 being connected two by two; the battery cells 100 have inwardly curved surfaces, and there are at least two battery cells 100 connected to each other, with the inwardly curved surface of one and the inwardly curved surface of the other facing oppositely. Because the two adjacent battery units 100 are reversely connected, stress buffering is formed between the two connected battery units 100, so that the bending of each battery unit 100 is buffered, and the packaged flexible solar battery assembly is in a flat state. Because the stress is fully released when the flexible battery pack is packaged, the bending phenomenon is reduced, and the flexible battery pack is in a flat state, the reliability and the stability of the flexible battery pack are greatly improved.
Specifically, in two of the battery cells 100 connected to each other, the inwardly curved surface of one of the two is opposite to the inwardly curved surface of the other, and the inner walls of the two inwardly curved surfaces are connected to each other.
Specifically, the battery cell 100 includes a substrate 150 with a flexible battery chip or conductive buffer material disposed on the substrate 150. Of course, the battery cell 100 may take on different sizes, areas, or configurations; a conductive structure with opposite stress may also be used. The specific implementation manner may be adjusted according to the actual situation, and is not limited herein.
In certain embodiments, referring to fig. 1, a plurality of battery cells 100 are distributed in the lateral and longitudinal directions. The lateral and longitudinal connections allow a plurality of battery cells 100 to be connected as a large-area whole, thereby increasing the area of the flexible battery assembly available for electrical connection or power generation.
In some embodiments, referring to fig. 2, the battery cell 100 includes a positive electrode part 230 and a negative electrode part 250, and the positive electrode part 230 of one of the two adjacent battery cells 100 connected in the transverse direction is connected with the positive electrode part 230 of the other. The interconnection of the plurality of positive electrode portions 230 may increase the area of the positive electrode portions 230, thereby substantially increasing the area of the flexible battery assembly available for electrical connection or power generation. Meanwhile, because the front surface and the back surface are both provided with the batteries, both sides of the battery component can absorb sunlight to generate electricity.
Specifically, in the two battery cells 100 connected in the lateral direction, the two positive electrode portions 230 are pressed against each other.
In some embodiments, referring to fig. 4, the positive pole portion 230 is disposed on the curved inward surface and the negative pole portion 250 is disposed on a side away from the curved inward surface. The positive electrode portions 230 may be connected to each other such that the inner curved surfaces are connected to each other. Since the two battery cells 100 connected to each other are oriented in opposite directions, the positive electrode portions 230 are urged against each other, so that the connection of the positive electrode portions 230 is more stable.
In some embodiments, referring to fig. 3, the battery cell 100 includes a positive electrode part 230 and a negative electrode part 250, and the positive electrode part 230 of one of the two battery cells 100 and the negative electrode part 250 of the other are electrically connected in the longitudinal direction. The positive electrode part 230 and the negative electrode part 250 are connected to each other so that the plurality of battery cells 100 can be electrically conducted as a whole in the longitudinal direction, thereby allowing the interconnected battery cells 100 to have higher integrity. Meanwhile, because the front surface and the back surface are both provided with the batteries, both sides of the battery component can absorb sunlight to generate electricity.
Specifically, of the two battery cells 100 connected in the longitudinal direction, the positive electrode portion 230 of one is electrically connected to the negative electrode portion 250 of the other through a conductive member. The conductive member may be a wire or a conductive screw. The specific implementation manner may be adjusted according to the actual situation, and is not limited herein.
In some embodiments, referring to fig. 1, the first electrode 300 is connected to one side of the plurality of battery cells 100 in the longitudinal direction, and the second electrode 400 is connected to one side of the plurality of battery cells 100 in the lateral direction. The first electrode 300 and the second electrode 400 are respectively positioned at two sides of the transverse direction and the longitudinal direction, so that the length of the flexible battery assembly in the transverse direction or the longitudinal direction can be reduced, and the problem of easy breakage caused by overlong length is avoided.
The invention also provides a battery manufacturing method for packaging the flexible solar battery assembly of the embodiment, which comprises the following steps:
A. a plurality of battery cells 100 are alternately arranged in a positive and negative direction;
B. connecting the plurality of battery cells 100 two by two;
C. the plurality of battery cells 100 connected as a whole are electrically connected to the external first electrode 300 and the second electrode 400.
Because the two adjacent battery units 100 are reversely connected and the inner curved surfaces are opposite, stress buffering is formed between the two connected battery units 100, so that the bending of each battery unit 100 is buffered, and the packaged flexible solar battery assembly is in a flat state. Because the stress is fully released when the flexible battery pack is packaged, the bending phenomenon is reduced, and the flexible battery pack is in a flat state, the reliability and the stability of the flexible battery pack are greatly improved. In addition, the arrangement mode is different from the traditional mode of firstly connecting in series and then connecting in parallel, so that the flexible battery assembly does not have the disconnection phenomenon caused by the abnormity of a single battery under the condition of not needing a bypass diode, and has higher stability.
