AI Customer ServiceMajor aspects of the multiphysics modeling of lithium-ion batteries are reviewed. The discharge and charge behaviors in lithium-ion batteries are summarized. The generation and the cross-scale transfer of stresses are discussed. Temperature effects on the battery behaviors are introduced.
At elevated temperatures, oxygen released from the cathode can react intensely with the electrolyte or anode, drastically raising the battery's temperature. The greater the amount of lithium retained in the anode (the higher the SOC), the greater the energy release upon reaction, and, consequently, the higher the risk of thermal runaway.
Generation and regeneration of the solid electrolyte interphase (SEI) and lithium planting are two of the most dominant side reactions in LiBs, the reaction rates of which are usually described using interfacial reaction kinetics [28, 29].
Similar to the effect of the SEI, the effects of lithium planting on battery performance can be divided into two areas. First, since there is also competition between the current of the generation of dead lithium and the current of the electrode intercalation reaction, this competition also leads to a decrease in battery power.
When discharging, the process is reversed: lithium ions migrate from the anode to the cathode and the cell voltage decreases. It is important to note that both the electrolyte and electrode materials operate optimally only within a specific potential range and that operation outside this range can cause interfacial reactions or material failure.
When the battery temperature reaches a certain threshold, the outer shell melts, effectively blocking the pores and ion transport. Lithium plating usually occurs in commercial LIB anodes and is one of the primary reasons for severe battery damage. Inhibiting Li metal plating is the way for practical implementation.
