  The interfaces between metal electrodes and liquid electrolytes are
prototypical in electrochemistry. That is why it is crucial to have a molecular
and dynamical understating of such interfaces for both electrical properties
and chemical reactivities under potential control. In this short review, we
will categorize different schemes for modelling electrified metal-electrolyte
interfaces used in molecular dynamics simulations. Our focus is on the
similarities between seemingly different methods and their conceptual
connections in terms of relevant electrochemical quantities. Therefore, it can
be used as a guideline for developing new methods and building modularized
computational protocols for simulating electrified interfaces.
