摘　　要：铝/铜异种金属的连接是研发和制造高能量密度、高效率、长寿命新能源锂离子电池的关键流程。但是铝和铜的热物理性能差异大且易形成脆性金属间化合物,固相焊接如超声波焊接被认为是适用于两者高质量焊接的方法之一。随着超声波焊接技术的不断发展,关于铝/铜异种金属超声波焊接的研究逐步由操作的可行性向铝/铜焊接接头的性能研究改变。为进一步分析铝/铜焊接接头性能的影响因素,基于超声波焊接机理,从界面显微组织、金属间化合物、接头强度等方面对铝/铜超声波焊接的研究现状进行了综述,总结了不同焊接参数对超声波焊接的影响,指出了超声波焊接的现有不足,并对其发展前景进行了展望。Al/Cu heterogeneous metal connection is the key process of developing and manufacturing new energy lithium-ion batteries with high energy density,high efficiency and long life.However,the thermophysical properties of aluminum and copper differ greatly and brittle intermetallic compounds are easily formed,so solid phase welding,such as ultrasonic welding,is considered to be one of the methods suitable for high-quality welding of aluminum and copper.With the rapid development of ultrasonic welding technology,the research on the ultrasonic welding of Al/Cu dissimilar metals has gradually changed from the feasibility of operation to the performance of Al/Cu welded joints.In order to further analyze the influencing factors on the properties of Al/Cu welded joints,based on the ultrasonic welding mechanism,the research status of Al/Cu ultrasonic welding was reviewed from the aspects of interface microstructure,intermetallic compounds,joint strength,etc.The effects of different welding parameters on the ultrasonic welding were summarized,the existing shortcomings of ultrasonic welding were pointed out,and its development prospects were reviewed.
