Abstract

The invention discloses a preparation method, a product and an application of an additive for high-end flexible porous electrolytic copper foil. The additive for the high-end flexible porous electrolytic copper foil is prepared from raw materials as follows: PN, SSO3, SDS, DEAE, EHS, DPS, M and PAP (30%). An electrodeposition technology is adopted, an electrolyte direct-current electrodeposition technology is included, the additive is added and mixed in the electrolytic process; in the electrolytic process, an electrolyte has the copper content being 80-120 g/L and the sulfuric acid content being 90-130 g/L, the temperature is controlled to range from 45 DEG C to 60 DEG C, the additive is added to the electrolyte, the flow of the electrolyte ranges from 60 m<3>/H to 90 m<3>/H, and direct-current electrodeposition is performed under the condition that the current density ranges from 4,500 A/M<2> to 6,500 A/M<2>.

Description

technical field [0001] The invention relates to the technical field of electrolytic copper foil production and manufacturing, in particular to a preparation method, products and applications of additives for producing 6um high-end flexible porous electrolytic copper foil. Background technique [0002] In recent years, the development of electronic technology has accelerated the pace of updating various electronic products. At the same time, various high-end digital products and electronic instrument products have appeared. With the continuous improvement of lithium batteries, the requirements for lithium batteries as the main energy source will become higher and higher, mainly reflected in the safety performance, battery life, and volume compression of lithium batteries. [0003] The power storage capacity of the battery is directly related to the amount of active material coated on the current collector. The negative electrode current collector of the lithium battery mainly...
