Investigation on the electrochemical performances of Li4Mn5O12 for battery applications

In this study, well-crystallized Li4Mn5O12 powder was synthesized by a self-propagating combustion method using citric acid as a reducing agent. Various conditions were studied in order to find the optimal conditions for the synthesis of pure Li4Mn5O12. The precursor obtained was then annealed at di...
