Battery aluminum foil and household aluminum foil have similarities and differences in many aspects.
Similarities
Material basis: Both household foil ma pepa pepa maa are made of high-purity aluminum materials. O le pepa alumini o loʻo i ai uiga faʻavae o le alumini, pei o le mamafa mama, ductility lelei, lelei eletise ma vevela conductivity, ma isi. Tete'e a'a: An oxide film can be naturally formed on the surface of aluminum foil, which can prevent further oxidation and corrosion of aluminum foil to a certain extent.
Different application fields: Battery aluminum foil: Mainly used for the positive electrode collector of lithium-ion batteries, it is one of the core components of lithium batteries. It is responsible for collecting the current generated by the active material of the battery in order to form a larger current output. Household aluminum foil: Widely used in daily life, e pei o le afifiina o meaai, kitchen utensils, ma isi. Its main function is to serve as a packaging material to prevent food from oxidation and deterioration, and as a cooking aid.
Different performance requirements: Battery aluminum foil: Compared with traditional aluminum foil, battery aluminum foil has higher requirements on performance indicators. It pursues the thinnest thickness, the highest strength, the highest dyne value, the smallest thickness difference, the best plate shape and the cleanest surface. These properties are crucial to the performance and service life of the battery. Household aluminum foil: The performance requirements are relatively low, and the main focus is on its corrosion resistance, ductility and processing performance.
Different production processes: Battery aluminum foil: The production process is complex, including casting, ta'avale malulu, intermediate annealing, foil rolling and other links. Each step is related to product quality, such as rolling force, rolling speed, annealing and other parameters will affect the consistency and yield of aluminum foil. Household aluminum foil: The production process is relatively simple, and the main focus is on its formability and processing performance.
Different thickness and specifications: Battery aluminum foil: The thickness usually ranges from 10 ia 50 microns, and the specific specifications vary depending on application requirements. Household aluminum foil: The thickness and specifications vary depending on the specific use, but it is generally thicker than battery aluminum foil.
Different chemical treatment: Battery aluminum foil: In order to improve its corrosion resistance and stability, plasma treatment and other technologies may be used to form a nano-level oxide layer on the surface. Household aluminum foil: E masani lava, no special chemical treatment is required, and the natural oxide film on its surface is sufficient to meet daily use needs.
Battery aluminum foil and household aluminum foil have similarities in material basis and corrosion resistance, but there are significant differences in application areas, performance requirements, production processes, thickness and specifications, and chemical treatment. These differences are mainly due to the different needs of the two in terms of function and use.
