Abstract
In this chapter we shall be concerned with diffusion of ions and electrons in a concentration or activity gradient and with their transport in an electric field. These two processes are often superimposed in which case it is more appropriate to speak of transport in an electrochemical potential gradient. The expressions to be derived are valid for the fluxes of each of the various types of ions and electrons separately. From these expressions the equations for cases in which the transport of various types of particles is interconnected can also be derived; an example is to be found in Chap. 8. Our discussion can be divided into a) a phenomenological treatment in which the transport processes are described in terms of experimentally measurable quantities such as diffusion coefficients, mobilities, partial conductivities or Onsager coefficients, and b) a statistical treatment in which the quantities involved in the phenomenological treatment are related to atomistic quantities.
