Abstract

The invention relates to a lithium battery production process, which relates to the technical field of batteries. The lithium battery production process comprises the following production process: preparing materials, producing a positive plate and a negative plate, baking a roll core, soaking the roll core in electrolyte, formatting, grading and assembling an aluminum shell, wherein in the roll core baking step, under a nitrogen environment, the baking temperature of the roll core is 50 to 55 DEG C, and the baking time is 6 to 12 h; in the step of soaking the roll core in the electrolyte, the roll core is soaked in the electrolyte, and the soaking time of the roll core is 1 to 2 h; and in a step of removing the electrolyte, the electrolyte incompletely absorbed by a pole piece diaphragm in the roll core is removed in a centrifugal manner or a vacuum manner. The lithium battery production process solves the technical problems of the existing lithium battery processing technology that the processing efficiency is relatively low, and the processing quality is relatively poor, and a technical effect of high processing efficiency and good processing quality of the lithium battery processing technology is achieved.

Description

technical field [0001] The invention relates to a lithium battery production process and relates to the technical field of batteries. Background technique [0002] Lithium-ion battery: It is a secondary battery (rechargeable battery) that mainly relies on lithium ions to move between the positive and negative electrodes to work. During the charging and discharging process, Li+ intercalates and deintercalates back and forth between the two electrodes: when charging, Li+ is deintercalated from the positive electrode, intercalated into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge. Batteries generally use materials containing lithium elements as electrodes, which are representatives of modern high-performance batteries. [0003] Lithium-based batteries are divided into lithium batteries and lithium-ion batteries. Lithium-ion batteries are used in mobile phones and laptops, commonly ...
