- 为制备出同时具备抗拉性能、延伸性能及光滑镀层的双面光锂电池电解铜箔,本文开展了对镀液添加剂配方的研发和添加剂组合的设计,利用现场工艺进行生产实验,研究表征了不同配方条件下制备的铜箔的形貌及结构,并测试分析了铜箔的粗糙度、光泽度、抗拉强度等物理性能。结果表明,当选择添加剂组合为胶原蛋白 - 聚二硫二丙烷磺酸钠( SPS ) - 聚乙二醇( PEG ) - 羟乙基纤维素( HEC ),添加剂浓度为胶原蛋白 1.5 mg/L 、 SPS 1 mg/L 、 PEG 1 mg/L 、 HEC 2 mg/L 时,制备的铜箔的物理性能最佳,抗拉强度 ≥ 340 MPa ,延伸率 ≥ 9.0% 。
- Abstract:
- : In order to prepare double-sided electrolytic copper foil for lithium battery with tensile and extensibility properties and smooth coating at the same time , the research and development of additive formula and additive combination were carried out in this paper. Production experiments were conducted using on-site processes to study and characterize the morphology and structure of copper foils prepared under different formula conditions , and physical properties such as roughness , glossiness , and tensile strength of copper foils were tested and analyzed. The results showed that when the additive combination was selected as collagen protein-bis- ( sodium sulfopropyl ) -disulfide ( SPS ), polyethylene glycol ( PEG ), hydroxyethyl cellulose ( HEC ), and the additive concentration was collagen 1.5 mg/L , SPS 1 mg/L , PEG 1 mg/L and HEC 2 mg/L , the physical properties of the prepared copper foil are the best , with tensile strength ≥ 340 MPa and elongation ≥ 9.0%.
