The assembled large vertical energy storage battery may be disposed within a container, for example. The large vertical energy storage battery can be used for injecting liquid at a use place. Electrolyte enters the side injection cavity 1403 through the injection port 9 and the injection pipe 11, and the electrolyte entering the side injection cavity 1403 does not flow into the front side cavity 1401 and the rear side cavity 1402, but enters the plug-in part 201 through the injection opening 204 of the cell holder, so that the cell 3 accommodated in the plug-in part 201 is infiltrated, the electrolyte entering the upper plug-in part also flows downwards, and part of the electrolyte entering the plug-in part 201 also enters the side discharge cavity 1404 through the discharge opening 205 of the cell holder until the electrolyte is fully filled in the side injection cavity 1403, the inside of the plug-in part and the side discharge cavity 1404 and each cell is completely infiltrated. The electrolyte stored in the side injection cavity 1403 and the side discharge cavity 1404 can make the battery in a rich state so as to timely supplement the electrolyte consumed in the electrochemical reaction process to the battery cell, thereby improving the service performance of the battery. During the liquid exchange process, the electrolyte in the side discharge cavity 1404 is pumped out through the discharge pipe 12 by the pumping device from the discharge port 10, and the electrolyte in the plug-in portion 201, the cell, and the side injection cavity 1403 enters the side discharge cavity 1404 under the action of the pumping force until the discharge pipe 12 pumps out all the electrolyte in the side discharge cavity 1404, the plug-in portion 201, the cell, and the side injection cavity 1403. Then, cleaning agent can be injected into the large vertical energy storage battery and discharged, and finally new electrolyte is injected. Since the bus plates (or there are also welded portions) placed in the front and rear cavities 1401 and 1402 do not contact the electrolyte, corrosion of the bus plates due to immersion in the electrolyte can be prevented, and failure of electrical connection of the bus plates and tab groups due to oxidation corrosion of the interface can be avoided.
