LIQUID INJECTION METHOD OF BATTERY, LIQUID INJECTION APPARATUS FOR BATTERY, AND BATTERY

摘要

PPROBLEM TO BE SOLVED: To provide a liquid injection method of a battery by which, electrolyte can be quickly injected into the battery, and to provide an liquid injection apparatus for the battery, and a battery. PSOLUTION: For the liquid injection method using the liquid injection apparatus for the battery, equipped with a desiccator (container) 1 housing a secondary battery 20 in its inside, a pump 3 for pressurizing and depressurizing the inside of the desiccator 1, and an electrolyte tank 2 containing the electrolyte to be injected into the secondary battery 20, injecting the electrolyte in a desiccator 1 by dropping the electrolyte liquid through a nozzle 7 formed to the upper part of the battery in the desiccator 1, the desiccator 1 is depressurized by the pump 3 to generate a pressure difference between the desiccator and the atmospheric air, and the electrolyte in the liquid tank 2 is injected into the secondary battery 20 by making the electrolyte liquid drop through the nozzle 7 by using the pressure difference, afterwards, the pressure in the desiccator 1 is changed by using the pump 3 to remove the bubbles in the secondary battery 20.
