Abstract: The disclosure relates to the field of batteries and specifically provides a battery pack including a box body, a cell stack, an adhesive blocking portion, and at least two adhesive structures. The box body has an installation space. The cell stack includes a plurality of soft-pack cells and is arranged in the installation space. The adhesive structures are arranged in the installation space and directly connected between the cell stack and the box body. The adhesive blocking portion is arranged between the at least two adhesive structures to isolate the at least two adhesive structures. In the battery pack, the adhesive structures may be used to provide more comprehensive support for the cell stack, and mutual interference between different adhesive structures may be prevented.

Abstract: The disclosure relates to the field of batteries, and specifically provides a battery pack and an electric vehicle. The battery pack has a casing including a lower case base plate and a beam structure, a cell stack formed by stacking multiple pouch cells in the casing, an electrode tabs extending from an end of the pouch battery cell toward the beam structure along a length direction of the pouch battery cell, a thermally conductive structural adhesive disposed between the battery cell stack and the lower case base plate, and a foaming adhesive filling a space between the electrode tabs and the beam structure. The solution can construct a pouch CTP battery pack based on the pouch cells, which has a good protective effect on the battery cell stack formed by stacking pouch battery cells and is easy to assemble, so as to improve the overall stability of the battery pack.

Abstract: Disclosed is a battery pack, including a casing, one or more battery cell stacks, and an electrode fixing component. The battery cell stack is formed by stacking a plurality of pouch battery cells along the thickness direction of the pouch battery cells. The electrode fixing component includes bus bars and a bus bar bracket supporting the bus bars. The bus bar bracket is cooperatively connected with a fixing structure on the casing, and the bus bars are cooperatively connected with an electrode of the battery cell stack.

Abstract: The disclosure relates to the technical field of batteries and specifically provides a battery pack and an electric vehicle. The battery pack includes a box body having a lower casing bottom plate, a cell stack formed by stacking a plurality of soft-pack cells, a thermally conductive structural adhesive arranged between the cell stack and the lower casing bottom plate, side plates arranged at both ends of the cell stack in a stacking direction and adhered to main body surfaces of the soft-pack cells at both ends, and fixture fitting portions arranged on surfaces of the side plates opposite to the soft-pack cells. In the solution, a soft-pack cell to pack (CTP) battery pack is constructed based on the soft-pack cells, the cell stack formed by stacking the soft-pack cells can be well protected, and assembly can be easily performed.

Abstract: The present invention discloses a method for isolating placental trophoblast cells from cervical exfoliated cells of a pregnant woman. Based on a specific antigen or combination expressed on the surface or inside of specific trophoblast cells, the designed microfluidic sorting chip or flow cytometer is used in the method to perform cell sorting of a cell suspension of a placental trophoblast sample, thus obtaining isolated and purified placental trophoblast cells. Compared with conventional methods, the method of the present invention has the advantages of non-invasively obtaining specimens and good specificity. Moreover, the method causes low risk of infection and abortion, allows earlier sampling time and can achieve the synchronous labeling of a plurality of antigens as well as identification and sorting of characteristic fluorescence signals; and the method has greatly improved accuracy and higher reliability and broader coverage area of detection results.
