Electrochemical Characteristics of Spinel Phase LiMn2 O 4‐Based Cathode Materials Prepared by the Pechini Process: Influence of Firing Temperature and Dopants

This is the authors' abstract. We don't add key points for this paper.

In the past ten years, ‐based spinels have been extensively studied as positive electrode materials for lithium‐ion batteries. Our 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 ‐based cathode materials. It also has been shown that different firing temperatures and the selective doping of both produce materials with different electrochemical characteristics that merit further exploration.
