The production process of the lithium battery comprises an aging process, wherein the aging process is generally carried out after formation, the battery is baked at high temperature to accelerate battery aging, the aging of the lithium battery can accelerate the completion of chemical side reactions in the battery and fully infiltrate electrolyte, and simultaneously, the positive electrode, the negative electrode and trace active ingredients in the electrolyte are inactivated after certain reactions, so that the stability of the overall performance of the lithium battery is improved, the consistency of the finished battery is improved, and the cycle service life of the finished battery is prolonged.

The soft package lithium battery is a lithium battery using an aluminum-plastic packaging film as a packaging material, and the assembly process comprises the following steps: the method comprises the steps of aluminum plastic film forming → liquid injection, pre-sealing → standing, formation → aging → air extraction, secondary sealing forming → capacity test and battery self-discharge rate detection, wherein the liquid injection is to inject sufficient electrolyte into an aluminum plastic packaging film air bag with a sealed top side to fully soak the pole pieces. However, a large amount of electrolyte is concentrated between the flexible-package battery core and the aluminum-plastic packaging film, which causes poor appearance such as liquid expansion of the flexible-package battery, and the excessive electrolyte is not absorbed by the battery core, and is easily extracted and volatilized in a vacuum environment in an extraction molding process (extracting gas generated in the formation process) after liquid injection and formation, thereby wasting the electrolyte and increasing the manufacturing cost. Therefore, the aging process after the formation process and before the air extraction forming process directly affects the absorption capacity of the battery cell in the soft-package lithium battery on the electrolyte, thereby affecting the manufacturing cost and the cycle service life of the lithium battery.
