Rethinking battery degradation in presence of surface effects: mechanical versus electrochemical peformance mediated by charging condition

no code implementations • 22 Feb 2021 • Amrita Sengupta, Jeevanjyoti Chakraborty

Surface stresses, in nano-sized anode particles undergoing chemomechanical interactions, have a relaxing effect on the diffusion-induced stresses thus improving the mechanical endurance of the particles, whereas, the compressive effect of surface stresses degrades the electrochemical performance.
