Dynamic process of ion injection into nickel oxide him in both KOH and LiCl
O4-PC electrolyte were studied using electrochemical measurement. Cottrell
and Butler-Volmer current-time relations were applied to obtain ion diffusi
on coefficient D and exchange current I-ex by fitting the experimental data
. Results showed that the him displays complex transport behavior which dep
ends on the deposition rate of the film, the environment and sequence of he
at treatment, the adopted electrolyte. The change of the number of the oxyg
en and nickel vacancies are suggested to be responsible for the phenomena.
