Theoretical prediction of equivalent stiffness of anode and cathode coatings in lithium-ion batteries

Anode and cathode in flexible lithium-ion batteries (LIBS) are built by coating aluminum and coppersubstrates, respectively. These coatings have two parts, matrix, and nanoparticles. Adding nano-particles to the matrixchange the overall stiffness of the matrix. Understanding the nanocomposite coating behavior in bending can helpresearchers to predict LIBS’s failure mechanisms. The present research investigates the equivalent stiffness ofnanocomposite coating via developing a code in MATLAB with four different homogenization methods. Results showthat the modified differential scheme is the best approach to predict the equivalent stiffness of nanocomposite coatingwith high nanoparticle volume fractions in comparison with other methods.
