بیٹری ایلومینیم ورق ایک اہم نئی توانائی کا مواد ہے۔, مختلف بیٹری مصنوعات جیسے لتیم بیٹریوں میں وسیع پیمانے پر استعمال کیا جاتا ہے۔, نکل ہائیڈروجن بیٹریاں, اور نکل کیڈیمیم بیٹریاں. یہ نہ صرف بڑے پیمانے پر استعمال ہوتا ہے۔, لیکن بیٹریوں کی کارکردگی پر بھی اہم اثر پڑتا ہے۔. Let’s introduce the technical parameters of battery aluminum foil in detail.
1. موٹائی: The thickness of battery aluminum foil is usually between 12um-50um. Different battery types have different requirements for thickness. مثال کے طور پر, nickel-hydrogen batteries are mostly around 20um. Lithium batteries are usually around 15um. 2. چوڑائی: The width of battery aluminum foil also varies according to different battery types, generally between 100mm-1000mm. 3. طاقت: The strength of battery aluminum foil refers to its tensile strength and tensile modulus. عام طور پر بولنا, the tensile strength of battery aluminum foil is above 150MPa, and the tensile modulus is above 90GPa. 4. Surface condition: The surface of battery aluminum foil is required to be flat, without obvious scratches, oxidation and pollution defects to ensure good welding performance and battery performance.
Battery aluminum foil is mainly made of high-purity aluminum, and its chemical composition mainly includes aluminum (AI) and a small amount of impurity elements. In general, the aluminum content of battery aluminum foil is above 99.7%, and the content of impurity elements such as silicon, لوہا, copper, وغیرہ. needs to be controlled at an extremely low level.
The surface treatment of بیٹری ایلومینیم ورق has an important influence on its final performance, mainly including oxide film treatment, coating treatment and rolling treatment
1. Oxide film treatment: The oxide film of battery aluminum foil is its surface protective layer, which can improve its corrosion resistance. عام طور پر, صفائی, pickling, oxidation and other treatment processes are used to form a uniform oxide film.
2. Coating treatment: In order to improve the conductivity and welding performance of battery aluminum foil, coating treatment is usually performed on its surface. Conductive coating or welding coating is generally used to meet different requirements.
3. Rolling treatment: After rolling treatment, battery aluminum foil can obtain a certain surface roughness and flatness to ensure the molding and welding performance of its final product.
4. Application scope of battery aluminum foil.As a key battery material, battery aluminum foil is widely used in various battery products such as lithium batteries, نکل ہائیڈروجن بیٹریاں, اور نکل کیڈیمیم بیٹریاں. It is not only used for positive and negative electrode foils of batteries, but also for battery current collectors and packaging materials.
5. Quality control of battery aluminum foil
As an important material for batteries, quality control of battery aluminum foil is crucial. During the production process, it is necessary to strictly control the thickness, چوڑائی, surface condition, chemical composition and surface treatment parameters to ensure the performance and stability of the final product. Strict quality inspection and control are required to ensure that the quality of battery aluminum foil meets customer requirements.
As an important material for batteries, the technical parameters of battery aluminum foil have an important impact on the performance and stability of batteries. Manufacturers need to have a deep understanding of the requirements of different types of batteries for the performance of battery aluminum foil, continuously optimize the process, improve product quality, and meet market demand.
