Abstract Mechanical failure due to lithium-ion diffusion is one of the main obstacles to fulfill the potential of the
electrode materials. Various fracture patterns in different electrode structures are observed in practice,
which may have a profound impact on the performance and the service life of electrodes during operation.
However, the mechanisms are largely unclear and still lack systematic understanding. Here we propose a
coupled chemo-mechanical model based on peridynamics [1] and use it to study the dynamic fracturepattern formation in electrode materials and solid electrolytes during lithiation/delithiation cycles. We
found in hollow core-shell nanowires that geometric parameters such as the… More >
