Recasting the double layer: The implicit assumption that electrochemical double layers are governed only by ion/electrode charge separation may be short‐sighted and lead to a fundamental misunderstanding of the phenomenological response. This is shown in a study performed on ions confined in nanoporous carbon with pores smaller than the size of an ion surrounded by a solvation shell (see picture; TEA + =tetraethylammonium, AN=acetonitrile).
