Stress Analysis of Coated Thin Foils in Flexible Batteries under Static Bending Load: A Finite Element Approach

Thin foils are used in diverse industries, including aerospace, electronics, and other sensitive sectors. The electronics industry’s rapid advancements and the growing need for portable devices have created a vital opportunity for innovative battery technology. The crucial role of thin foils in flexible battery design has led to significant research interest. This study examines stress distribution in thin foils and their coatings during static bending, focusing on how these materials respond to significant deformation under load at the cathode and anode. The simulation of a full battery pack under static bending loads was conducted using finite element techniques, enabling a comprehensive examination of stress distribution within the layers of bendable batteries. The study reveals that the onset of damage in the battery layers is highly influential in determining the mechanical efficacy of the battery system.
