The invention relates to the technical field of new energy, and discloses a battery and a battery device.The battery comprises a shell assembly and a winding battery cell, the winding battery cell comprises a barrier layer, the barrier layer comprises a base film sub-layer and an adhesive sub-layer, and the barrier layer is bonded to the surface of an active substance layer corresponding to a bending part through the adhesive sub-layer; at least one end of the negative plate exceeds the positive plate, and the size of the exceeding part in the first direction is m; a through hole penetrates through the base film sub-layer along the thickness direction, and the air permeability of the barrier layer is n; the thickness of a single winding cell is q; m, n and q meet the relational expression that (q * m) / n is larger than or equal to 0.0045 and smaller than or equal to 1.65. According to the battery provided by the invention, (q * m) / n is controlled in an adaptive range, so that the coordination of the lithium embedding uniformity of the negative electrode, the ion transmission efficiency and the structural stability can be realized.

A disposable absorbent article having a transverse axis X and a longitudinal axis Y. The disposable absorbent article comprises a liquid-permeable surface layer, a liquid-impermeable bottom layer and an absorbent core, the disposable absorbent article further comprises a wing portion, the wing portion comprises at least one main wing panel, at least one first auxiliary wing panel and at least one second auxiliary wing panel, the first auxiliary fin extends along a first imaginary line and has a first angle of the first imaginary line relative to the transverse axis X. The second auxiliary fin extends along a second imaginary line and has a second angle of the second imaginary line relative to the transverse axis X. The first auxiliary wing piece and the second auxiliary wing piece which have a certain inclination degree relative to the transverse axis are arranged on the basis of the main wing piece and are used in cooperation with the fixing area, the upper portion, the middle portion and the lower portion are jointly positioned, the area of the wing portions fixed to the surface of the underpants is increased, the fixing effect of the wing portions is guaranteed, and the phenomena of displacement, wrinkling, turnover and the like of the sanitary towel are avoided. And the leakage-proof performance of the sanitary towel is further improved.

The invention belongs to the technical field of photovoltaic module production, and discloses hot pressing equipment and a photovoltaic module packaging production line. The hot pressing equipment comprises a supporting frame body, an assembly conveying mechanism arranged on the supporting frame body, at least four restoration mechanisms, an assembly adsorption supporting mechanism and at least four hot pressing mechanisms, and the assembly conveying mechanism is used for conveying photovoltaic assemblies in the conveying direction. The at least four restoration mechanisms are used for correcting the position of the photovoltaic module on the module transmission mechanism; the assembly adsorption supporting mechanism is used for adsorbing the photovoltaic assembly and lifting the photovoltaic assembly to a set height; the at least four hot-pressing mechanisms can be close to the photovoltaic module and hot-press the water-blocking adhesive tape around the photovoltaic module. The waterproof adhesive tape for the photovoltaic module is further hot-pressed after being pasted, and the problems that the waterproof adhesive tape is prone to falling off and poor in waterproof performance are solved.
