The production process of carbon battery involves multiple links, each of which has its key points of quality control, and the corresponding detection technology is also crucial.
First of all, the inspection of raw materials is the basis. For raw materials such as carbon rods, zinc cylinders, electrolytes and various additives, their purity, physical properties, etc. must be strictly tested. For example, the conductivity of carbon rods, the thickness and uniformity of zinc cylinders directly affect the performance of batteries. Through professional component analysis instruments and physical performance testing equipment, ensure that the raw materials meet the quality requirements and eliminate battery quality defects caused by raw material problems.
In the electrode production link, the key lies in controlling the molding quality of the electrode and the coating uniformity of the active material. The dimensional accuracy, surface flatness, and content and distribution of the active material of the electrode will affect the reaction efficiency and capacity of the battery. Use high-precision molds and automated coating equipment, combined with optical microscopes, X-ray fluorescence spectrometers and other detection methods to conduct random inspections of electrodes to ensure stable electrode quality.
The preparation of electrolyte requires precise control of concentration and component ratio. Excessive errors may cause abnormal chemical reactions inside the battery and affect discharge performance. Use high-precision measuring instruments and chemical analysis methods, such as titration method to detect pH, to ensure that the electrolyte is accurately prepared.
In the process of carbon battery assembly, the assembly accuracy and sealing of each component are key. Improper assembly may cause short circuit or leakage. Through automated assembly production lines and strict process specifications, combined with air tightness testers, insulation resistance testers and other equipment, the assembled batteries are fully tested to ensure assembly quality.
The formation process is an important step in activating the battery. The current, voltage and time parameters of the formation must be controlled. These parameters affect the initial performance and service life of the battery. Use a professional electrochemical workstation to monitor the current and voltage curves during the formation process, and judge whether the formation effect meets the standards based on the standards.
The appearance inspection of the battery should not be ignored. Check whether the battery shell is scratched or deformed, and whether the label is clear and complete. Through manual visual inspection combined with automated appearance inspection equipment, select products with qualified appearance.
Finally, the finished carbon battery is subjected to comprehensive performance tests, including capacity test, discharge curve test, self-discharge rate test, etc. We use professional battery testing systems to simulate different usage scenarios to ensure that carbon batteries meet quality standards in all performance indicators. Only carbon batteries that have passed strict testing can enter the market and provide consumers with reliable power supply.
