The embodiment of the utility model provides a battery monomer, a battery device and a power utilization device, and belongs to the technical field of batteries. A battery cell including: a housing; a pole mounted on the housing; the electrode assembly is arranged in the shell, the distance between the folded position of a tab of the electrode assembly and the first side of the shell in the thickness direction is larger than the distance between the folded position of the tab and the second side of the shell, and the folded part of the tab is folded towards the first side; the support is arranged between the shell and the electrode assembly and forms an opening used for leading out the tab, the distance between the opening and the first side is larger than the distance between the opening and the second side, and the folded part of the tab extends out of the opening to be electrically connected with the pole. Through the common offset design of the folding position of the tab and the opening of the bracket, a larger folding space is provided for the tab, the risk of tab breakage is reduced, the bending times of the folding part can be reduced, the risk that the tab is broken from a stress concentration part after long-term use is reduced, and the performance and the reliability of the battery monomer are improved.

The utility model provides a kind of track type warehouse shelves, including warehouse shelves main body and ball bearing seat, and multiple groups of reinforcing angle steel are installed in the left and right ends of warehouse shelves main body inside by bolt, multiple reinforcing angle steel between horizontal welding has multiple horizontal fixed plates, multiple rectangular barrel grooves are opened in the upper end of multiple horizontal fixed plates, and strip sliding slot is opened in the left and right ends of multiple rectangular barrel grooves inside, ball bearing seat is provided with multiple groups, this design solves the problem that original track type warehouse shelves push out mechanism component occupies larger space, only a small amount of goods storage can be carried out, cannot be used for a large amount of goods storage, and the practicability is lower, the utility model uses array thread transmission structure, can realize the removal of shelf placement board, it is convenient to store or take goods, and simple operation, it will not occupy larger storage space, cooperate with magnetic attraction locking structure, effectively prevent shelf placement board from shaking and other adverse phenomena.
