0.015mm high-performance double-sided photocell foil and production method thereof

Abstract

The invention discloses 0.015mm high-performance double-sided photocell foil and a production method thereof, and belongs to the technical field of materials. Components of the 0.015mm high-performance double-sided photocell foil comprise, by mass percent, 0.1%-0.15% of Si, 0.38%-0.45% of Fe, 0.08%-0.1% of Cu, 0.01% of Mn, 0.03% of Zn, 0.015%-0.03% of Ti, 99.3% of Al and the balance other unavoidable components. The production method of the 0.015mm high-performance double-sided photocell foil comprises the following working procedures of cast rolling, cold rolling, aluminum foil blank rolling, rough rolling, intermediate rolling and finish rolling of 0.015 mm. The 0.015mm high-performance double-sided photocell foil is scientific in design and ingenious in thought, and the 0.015mm high-performance double-sided photocell foil with good quality is prepared by adjusting the proportion of the alloy components and process parameters in the production process.

Description

technical field [0001] The invention belongs to the field of material technology, and in particular relates to a 0.015mm high-performance double-sided photovoltaic foil and a production method thereof. Background technique [0002] The development of new energy vehicles is an important part of the low-carbon economy, which plays an important role in alleviating the contradiction between energy supply and demand, improving the environment, and promoting sustainable economic development. The power battery used in electric vehicles is a lithium battery, and the aluminum foil in the lithium battery exists as a current collector of the positive level. The battery aluminum foil is different from ordinary single and double zero foils. There are high requirements for performance, dyne value, surface quality, residual oil, etc. Hangzhou Wuxing Aluminum, as one of the earliest manufacturers of battery foil in China, has been committed to the process research and new product developmen...

AI Technical Summary

Problems solved by technology

[0007] The production of 0.015mm high-strength double-sided glossy aluminum foil, because of its high strength and elongation, there are many technical problems to be overcome in production, mainly: 0.015mm high-strength double-sided glossy aluminum foil, metal plastic deformation is very difficult, alloy It feels brittle and hard, it is difficult to produce finished products, the probability of strip breakage is high, and it is difficult to form a stable rolling process; the tensile strength is required to be above 250Mpa, and the elongation is above 4%, which has far exceeded the normal performance of aluminum foil products. Scope; quality requirements are strict, and no obvious plate shape defects are allowed; rolling processing is difficult, and the reduction rate has many passes, and the reduction rate of individual passes is low, the rolling force is increased, and the speed is fast, which makes the production The probability of surface chatter marks and plate shape defects increases during the process
