摘要:以阴极副反应析出的氢气泡为动态模板,在由60 g/L CuSO4ꞏ5H2O、90 g/L 硫酸、60 ~ 90 g/L 聚乙二醇(PEG)和0 ~ 40 mg/L NaBr 组成的电解液中电沉积30 s,制备了锂离子电池用三维多孔铜薄膜。研究了电流密度、镀液温度以及添加剂NaBr 和PEG的用量对制备铜薄膜孔径和孔壁质量的影响。结果表明,电流密度在3 ~ 5 A/dm2 范围内才能制得三维多孔结构,增大溴离子浓度和升高镀液温度都可扩大孔径,孔壁结构也会变得更加致密。

Effects of process parameters on microstructure of porous copper film prepared using hydrogen bubble dynamic template // ZHANG Yan, LI Li*, ZHAO Yu-gang, YANG Xiang-kui, XU Shu-min, LIU Yun, CUI Cheng

Abstract: Three-dimensional porous copper films used for lithium-ion batteries were prepared by electrodeposition for 30 s in an electrolyte comprising CuSO4ꞏ5H2O 60 g/L, H2SO4 90 g/L, polyethylene glycol (PEG) 60-90 g/L, and NaBr 0-40 mg/L with hydrogen bubbles released from the side reaction at cathode as dynamitic template. The effects of current density, bath temperature, and contents of additives including NaBr and PEG on the pore size and pore wall properties of copper film were studied. It is shown that three-dimensional porous structure can only be obtained in the current density range of 3-5 A/dm2. The increase of bromine ion concentration and bath temperature increases the size of pores, and makes the pore walls become more compact.

Keywords: porous copper film; acid copper electroplating; hydrogen evolution; templating method; morphology
