LiMn2O4 nanoparticles as cathode in aqueous lithium-ion battery

The aqueous lithium–ion batteries using LiMn₂O₄ as cathode materials are considered to be one of the most promising stationary power sources for large-scale energy storage devices. In the present work, LiMn₂O₄ nanoparticles were successfully synthesized by using sol-gel method, and the morphology of particles was characterized by SEM. We made three electrodes of this active material with PVDF binder and different conductive agents and another electrode of this active material with PTFE binder and Vulcan as a conductor. Electrochemical performances were tested in 5 M LiNO₃ aqueous electrolyte, and comparisons between these electrodes were accomplished.
