Therefore, the effector forces, such as Von Mises, within the particle gradually decrease. According to the calculation of Equation (22), the electrode diffusion stress reaches the maximum at the end of discharge, so rupture is most likely to occur at the surface of the negative-electrode active particle.
Additionally, anode failure of lithium-ion battery could also be caused by the formation of lithium dendrite. During the processes of charge and discharge, lithium dendrites gradually accumulate on the anode due to the uneven deposition. The persistent growth of the lithium dendrite is likely to cause the separator penetration [ 72 ].
The reaction of the anode with the electrolyte results in the formation of compounds on the anode surface, such as ROCO 2 Li and CO 2 OLi. Meanwhile, the formation of SEI layer causes the loss of the lithium ion, which decreases the reversible capacity and the Coulombic efficiency of the anode material.
The anode failure restricts the electrochemical performance and cycle life. Therefore, it is of great importance to investigate the failure mechanism of the anode material. Herein, we summarized the recent advances of different anode failure mechanisms attained by using various methods ( Table 2 ).
In order to increase the accuracy of the model, the effect of the thermal expansion of the battery on the expansion displacement of the battery is added by intercalation replacement, and the concentration-dependent volume change is used in the graphite electrode to improve the accuracy of the model .
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.
