In the past ten years, LiMn{sub 2}O{sub 4}-based spinels have been extensively studied as positive electrode materials for lithium-ion batteries. Ongoing investigations have shown that the Pechini process, a low temperature synthetic method that often yields inorganic oxides of excellent phase purity and well-controlled stoichiometry, is very effective for preparing LiMn{sub 2}O{sub 4}-based cathode materials. It also has been shown that different firing temperatures and the selective doping of LiMn{sub 2}O{sub 4} both produce materials with different electrochemical characteristics that merit further exploration.
