Structure and electrochemical hydrogen storage properties of spinel ferritesSm_xZn_1−xFe₂O₄alloys (x = 0,x = 0.2,x = 0.4, andx = 0.6) forNi‐MHaccumulator applications

Abstract

In this article, we examine the effects of Sm substitution by Zn on the structures and electrochemical characteristics of Sm x Zn 1Àx Fe 2 O 4 alloys prepared by sol-gel technique. The structural properties of the electrodes are studied by X-ray diffraction and scanning electron microscope (SEM). The structural properties of these alloy are well
