double-layer current

https://doi.org/10.1351/goldbook.D01847
The non-
faradaic current
associated with the charging of the
electrical double layer
at an electrode-solution
interface
, given by: iDL=d(σ A)dt where σ =
surface charge density
of the double layer, A = area of the electrode-solution
interface
and t = time. Capital letters should be used as subscripts to avoid the possibility of confusing this symbol with that for the
limiting diffusion current
.
