Abstract
A mathematical analysis of the diffusion process is carried out to examine the validity of the classical treatment when the diffusion coefficient depe nds on the concentration. Investigations concerning the analysis of interca lation processes by transient electrochemical techniques are examined. A di gital simulation programme is used to obtain an accurate description of the transport mechanism. Examples of lithium intercalation in a Nb2O5 matrix a re given. (C) 2000 Elsevier Science Ltd.
