Journal ArticleDOI
The Spinel Phase of LiMn2 O 4 as a Cathode in Secondary Lithium Cells
TL;DR: In this paper, the electrochemical properties of spinel and spinel cells were studied for different conditions of sample preparation and different degrees of cation substitution, and it was shown that replacing Mn with cations of valence 2 (Ni, Zn) or 3 (Fe) reduces the amount of Mn+3 and correspondingly reduces the capacity of the cells at 4.1 V, but does not affect their cycling performance.
