Fracture is an overwhelming issue in electrodes of intrinsically large deformation associated with Li reactions (Liu et al., 2012, Lee et al., 2015). The formation of extensive cracks in the early state of the electrochemical reactions causes catastrophic failure of batteries.
Three typical types of electrode-level fractures, namely, the fracture of an active layer, the interfacial delamination, and the fracture of metallic foils in electrodes (including the current collector and the lithium metal electrode), have been discussed.
Prediction of elevated cracking due to enlarged cycling voltage windows. Cracking shown to occur as a function of electrode thickness. Increasing damage as the rate of discharge is increased. Fracture of lithium-ion battery electrodes is found to contribute to capacity fade and reduce the lifespan of a battery.
Long-term durability is a major obstacle limiting the widespread use of lithium-ion batteries in heavy-duty applications and others demanding extended lifetime. As one of the root causes of the degradation of battery performance, the electrode failure mechanisms are still unknown.
An electrode in a lithium-ion battery commonly includes a metallic current collector whose one side or both sides are connected with active layers, with the lithium metal electrode being the exception (see Subsection 4.2 ).
