AI-generated summary of the article: This research investigates how repeated bending affects the mechanical integrity and electrochemical performance of ultrathin lithium-ion pouch cells, a crucial aspect for developing reliable flexible electronics. By examining three different capacity pouch cells under horizontal and vertical bending, the study identifies several failure modes, including crack propagation, particle detachment, and separator damage, which are influenced by electrode size and shape, cell component configuration, and bending orientation. The findings reveal that capacity retention after flexing is best when the bending axis aligns with the cell's longest dimension and highlight the importance of material properties and cell design in mitigating mechanical failures that lead to electrochemical degradation. Ultimately, this work provides valuable insights for designing more dependable flexible lithium-ion batteries.
