Synthesis of nanoarchitectured LiNi0.5Mn0.5O2 spheres for high-performance rechargeable lithium-ion batteries via an in situ conversion route
Abstract
LiNi0.5Mn0.5O2 nanoarchitectured spheres (NA-LiNi0.5Mn0.5O2) have been synthesized via an in situ conversion route derived from the use of γ-MnO2 hollow nanostructured spheres. The complete conversion of the γ-MnO2 precursor to layered α-NaFeO2-type NA-LiNi0.5Mn0.5O2 has been confirmed by
