Electrode Charge Transport Equations
Ohm’s law describes the transport of charge in the electrode’s current collectors and feeders:
In the porous electrode domains the following expression is used:
where
ε
denote the porosity of the electrode and
exm
is an empirical parameter that describes the correction factor for the effective transport properties.
Current conservation is described by
. Here
Q
s
is the sum of all current contributions.
