The Effect of Buckling on the Interface Conductance in Flexible Lithium-Ion Batteries

Flexible batteries used in flexible applications including medical implants, wearable electronics, consumer electronics or roll-up displays are often subjected to bending and buckling during their operation life. It is imperative to investigate the impact of buckling on the performance of the flexible lithium ion battery (LIBs). In this study, flexible thin-film lithium ion batteries based on solid nanocomposite polymer electrolyte were fabricated. The interfacial impedance in fresh and cycled flexible LIBs was investigated in flat and buckled configurations using electrochemical impedance spectroscopy (EIS). It is demonstrated that with increasing value of curvatures, contact resistances between components can be reduced and contact conductance of LIBs can be enhanced.
