Cs. Cha et al., POLYPYRIDINE COMPLEXES OF IRON USED AS REDOX SHUTTLES FOR OVERCHARGE PROTECTION OF SECONDARY LITHIUM BATTERIES, Journal of power sources, 54(2), 1995, pp. 255-258
The 2,2'-bipyridyl and 1,10-phenanthroline complexes of iron, which sh
ow oxidation potential similar to 0.7 V more positive than that of fer
rocene, were studied for their possible use as redox shuttles for the
overcharge protection of secondary lithium batteries. The shuttle volt
age was found to be around 3.8-3.9 V. The electrochemical stability of
these complexes at the electrodes of lithium batteries was also inves
tigated.
