Aluminum foil for negative current collector of sodium ion battery

Номер: CN116278232A
Автор: CUI GUANGJIAN, DING XIAOLI, ZHANG SHANGLING, WANG JIAPENG
Принадлежит:

The invention discloses an aluminum foil for a negative current collector of a sodium ion battery, which is prepared by laminating a pretreated aluminum foil coating adhesive, and the pretreated aluminum foil comprises the following raw materials in percentage: 0.15-0.18% of Cu, 0.50-0.70% of Fe, 0.20-0.30% of Si, less than or equal to 0.01% of Mn, less than or equal to 0.01% of Mg, less than or equal to 0.03% of Ti and the balance of A and other inevitable impurity elements. The variety and content of components are limited, and intermediate annealing is carried out after rough rolling is completed, so that the internal stress defect generated by rolling is eliminated, and the uniformity of an alloy structure is effectively improved. After cast rolling, intermediate annealing and cold rolling, the dislocation density of the aluminum foil can be improved in cooperation with subsequent pass rolling, and therefore the problems that the aluminum foil of the lithium battery is prone to breakage ...
