Description

Bipolar horizontal battery capable of preventing liquid and gas channeling Technical Field The invention relates to the technical field of storage batteries, in particular to a bipolar horizontal battery capable of preventing liquid and gas from flowing out. Background Batteries are widely used in various fields in the current society. The types of batteries are also varied depending on the application. Among them, a horizontal battery, which is one type of stacked battery, is generally used as a large-capacity battery because it can include a plurality of battery cells, and is applicable to starting of automobiles, ships, construction machines, airplanes, locomotives, etc., and is also applicable to various fields such as energy storage, backup power, forklifts, etc. The conventional horizontal battery manufacturing process is to manufacture a battery core (a plurality of single battery clusters formed by stacking and fixing a bipolar plate, a positive single plate, a negative electrode plate, a diaphragm and the like) and a battery shell (also called a battery groove) of a horizontal battery respectively, then to mount the battery core in the battery shell and fix the battery shell in a combined manner, then to mount a top cover on the top of the battery shell, to seal the joint of the top cover and the battery shell, and finally to inject electrolyte into the battery shell, thereby forming a complete battery. However, the horizontal battery manufactured by the above process has at least the following disadvantages: Sealing between the individual battery cells of the battery cells is not easily accomplished. Since the individual cells of the battery need to be connected in series, they must be connected by means of conductors (e.g. wires) or by welding, but at the same time do not allow the passage of electrolyte between the individual cells. Therefore, it is generally necessary to design a specific structure to achieve sealing between the battery cells, preventing the occurrence of blow-by or blow-by between the battery cells. The mounting and fixing structure between the battery cell and the battery case is complicated, and a special structure for fitting with each other needs to be designed therebetween to ensure that the battery cell and the battery case are firmly fitted and fixed together, and positive and negative terminals can be led out from the battery cell to the outside of the battery case. The design of such mating structures increases the overall manufacturing cost of the battery and increases the complexity of the process, steps, and the like, as additional steps are required to assemble the battery cells and the battery case.
