There are many issues that need to be paid attention to during the production process of polymer lithium-ion batteries to ensure product quality and production safety. Here are some key considerations:
Material selection and proportioning: The production of polymer lithium-ion batteries involves a variety of materials, such as positive electrode materials, negative electrode materials, electrolytes and separators. Appropriate materials need to be selected and their proportions strictly controlled to ensure battery performance and safety.
Process control: During the production process, process parameters such as temperature, humidity, pressure and time need to be strictly controlled. Improper process control may result in reduced battery performance or safety hazards.
Equipment and environment: Production equipment requires regular maintenance and calibration to ensure its normal operation and accuracy. At the same time, the production environment also needs to be kept clean, dry and dust-free to avoid impurities affecting battery performance.
Safety measures: There may be safety risks such as fire and explosion during the production process of polymer lithium-ion batteries. Therefore, strict safety measures need to be taken, such as using explosion-proof equipment, conducting regular safety inspections, and formulating emergency plans.
Quality control and testing: Strict quality control and testing are required during the production process to ensure that battery performance meets standards. This includes testing of battery capacity, internal resistance, cycle life, etc.
Specifically, for a certain link in the production of polymer lithium-ion batteries, such as capacity division testing, it needs to be carried out in accordance with national standards. Generally, it is appropriate to use low-rate charging to avoid battery damage. In addition, it is also necessary to pay attention to the proportional relationship between the electrode surface and the compacted density of the electrode, the excess rate of the negative electrode, the formula process, and the appropriate amount of electrolyte and positive and negative electrodes.
During the entire production process, vacuuming operations need to be avoided, as this may lead to problems such as formula imbalance, reduced production efficiency, and slurry splashing. At the same time, it is also necessary to pay attention to the production process of the slurry to ensure the quality of the slurry.
