battery

Abstract

The invention discloses a storage battery. The storage battery is used for supplying power to an electric appliance component. The electric appliance component is provided with at least two wires and comprises a shell provided with a containing space, a positive electrode board and a negative electrode board which are located inside the containing space, a partition plate, a plurality of electrolytes and two polar columns, wherein the positive electrode board and the negative electrode board are provided with a plurality of grid frames and a plurality of active materials respectively, the grid frames are arranged at intervals, the active materials are stuck to the multiple grid frames, the partition plate is contained inside the containing space and located between the positive electrode board and the negative electrode board, the electrolytes are located inside the containing space and gaps inside the containing space are filled with the electrolytes; each grid frame is composed of a plurality of connecting strips, each connecting strip is provided with at least one hole or at least one protrusion or at least one hole and at least one protrusion, the active materials are stuck to the holes and the protrusions, the contact area between the active materials and the connecting strips is increased, and the phenomenon of disengagement is avoided.

Description

【Technical field】 [0001] The invention relates to a storage battery, in particular to a storage battery with a pole plate of an expanded grid. 【Background technique】 [0002] The storage batteries in the industry are all equipped with pole plates, and the pole plates are composed of positive plates and negative plates. When the positive plates and negative plates are expanded grids, the expanded grids are filled with slurry materials containing active material particles, so that Forming the positive plate and the negative plate, since the surface of the expanded grid is stamped and smooth, the active material particles and the expanded grid often fall off during the combination process, that is, the retention force is relatively small. [0003] Therefore, it is necessary to design a good storage battery to overcome the above problems. 【Content of invention】 [0004] Aiming at the problems faced by the background technology, the object of the present invention is to provid...
