Quantitative investigation of the influence of electrode morphology in the electro-chemo-mechanical response of li-ion batteries

Lithium ion batteries are promising energy storage devices for next generation electric and hybrid vehicles. To achieve high performances and overcome electrochemical deficiencies, significant effort has been made in novel electrode designs and materials. Structural features, such as the morphology of the electrodes, are crucial aspects, too. In this study, we investigate numerically the influence of electrodes architecture, in terms of the electro-chemo-mechanical response of a battery cell with homogeneous electrodes and conventional liquid electrolyte. Simulations predict a suitable design of the electrodes, which leads to major increments of the battery efficiency.
