Calculations are performed on the free energies for proton-promoted reactions of the lithium-ionbattery electrode material LiMn2O4 spinel in acid, as a function of lithium excess and lithium deficiency relative to stoichiometry. In particular, we consider the dissolution reaction proposed by Hunter (J. Solid State Chem., 1981, 39, 142), in which protons react with lithium manganate spinel to fo...

New energy industry including electric vehicles and large-scale energy storage in smart grids requires energy storage systems of good safety, high reliability, high energy density and low cost. Here a coated Li metal is used as anode for an aqueous rechargeable lithium battery (ARLB) combining LiMn2O4 as cathode and 0.5 mol l(-1) Li2SO4 aqueous solution as electrolyte. Due to the "cross-over" e...

Low-cost and efficient electrode materials play a key role in improving the performance of lithium-ion battery. In this paper, single-crystalline LiMn2O4 nanoparticles were synthesized through gel combustion method assisted by microwave followed calcination treatment. High-quality single-crystallinity characteristics precursor powder could be well retained after high-temperature (990 °C) solid-...
