Synthesis Conditions and Oxygen Stoichiometry Effects on Li Insertion into the Spinel LiMn2 O 4

Using a new electrolyte composition, which is stable against oxidation up to 5 V, the full electrochemical deintercalation of lithium from the spinel is studied. The origin of two new reversible oxidation‐reduction peaks near 4.5 and 4.9 V are examined. The capacity associated with these peaks depen... View More
