Abstract:

The processes of lithium redistribution in the structure of cubic Li 4Ti5O12 spinel, caused by both chromium doping and thermal activation, have been investigated by nuclear magnetic resonance. It is shown that Li ions migrate from tetra- to octahedral crystallographic positions with an increase in temperature. This process becomes more pronounced at temperatures above 400 K. In contrast, the fraction of tetrahedrally coordinated Li increases as a result of doping with chromium. © 2009 Allerton Press, Inc.
