Traditional modelling frameworks require approximations such as simplified surface models and an implicit description or neglect of electrolyte effects. A significant area for improvement is the treatment of the solid–liquid interface, where an explicit description of the electrolyte under realistic constant potential conditions remains the ultimate goal.

The dynamic evolution in AZIBs' response to applied bias potentials makes it difficult to accurately observe the behavior with current techniques in a non-vacuum environment. In response, theoretical simulations have been widely conducted to investigate the mechanisms of reactions occurring in the AZIBs. These theoretical simulations can considerably improve the understanding of the fundamental mechanisms, and further guide the AZIBs development.
