Effects of surface stress on lithium-ion diffusion kinetics in nanosphere electrodes of lithium-ion batteries
International Journal of Mechanical Sciences(2020)
摘要
•A chemo-mechanical model is established to study the size effect of nanosphere electrodes.•Surface stress-dependent diffusivity reduces with decreasing the size of electrodes ascribed to the strong effects of surface stress.•Surface stress has a significant impact on higher lithiation of nanoelectrodes on the near-surface region.
