Relationship between the electrochemical behavior and Li arrangement in Li(x)M(y)Mn(2-y)O4 (M = Co, Cr) with spinel structure.

The relationship between the electrochemical behavior and the arrangement of lithium/vacancies has been investigated with electrochemical Li removal in Li(x)M(y)Mn(2-y)O4 (x < or = 1.0, 0.0 < or = y < or = 0.
