The utility model is applicable to the technical field of lithium ion batteries, and provides a battery cell and a lithium ion battery. The adhesive tape is adhered to the side edge and / or the bottom of the battery cell body; the adhesive tape is provided with a hollow area penetrating through the adhesive tape. The hollow area is arranged on the adhesive tape, so that the hollow area can form a channel for the battery cell body to absorb free electrolyte while uniform stress and good shaping of the battery cell body are ensured, and the shaping effect of the battery cell and the battery performance can be effectively ensured.

This invention provides a method for fabricating precast box girder tracks for highways, belonging to the field of track fabrication technology. The method includes the following steps: S1: Concrete preparation, where screened cement, crushed stone, and sand are mixed according to a concrete mix design to obtain castable concrete; S2: Steel frame preparation, where steel bars and prestressed steel strands are combined after ensuring the materials are qualified to obtain a precast steel frame; S3: Concrete pouring, where the concrete pouring equipment includes a steel frame conveying mechanism for positioning and conveying the steel frame, a pouring mold for placing the steel frame for positioning and pouring, a demolding mechanism for quickly demolding the formed precast beam, and a moving pouring mechanism for uniform pouring; S4: Demolding and curing, where the precast beam is cured using curing equipment, ensuring that after the concrete pouring is completed and the slurry has settled, it is covered and watered for curing as soon as possible; S5: Finishing work. This invention facilitates rapid demolding of precast beams, achieving efficient demolding.
