Abstract
An electrochemical impedance spectroscopy study of Ni/MH batteries is repor ted. The surface structure change of MH electrodes during activation and ch arge/discharge cyclings of a Ni/MH battery is discussed by fitting EIS data to an equivalent circuit. The effect of surface treatment of hydrogen stor age alloys on the electrochemical parameters of the electrodes is also repo rted. (C) 1999 Published by Elsevier Science S.A, All rights reserved.
