Abstract: LiMn2O4 nanomaterials was synthesized by sol gel technique and calcined at 8000C temperature for different heat treatment time. The crystal structure and phase identification was done by X-Ray diffraction study; XRD revealed that the crystallite size decreased with increasing annealing time. Morphological, elemental analyses were carried out by FE-SEM and EDS showed the grain size in the range of 100-130 nm. XPS spectra confirmed Mn valency in +4 and +3 states. Dielectric study exhibited available free charge carriers at low frequencies within the material. Cyclic Voltammetry results showed that the sample annealed at 10h has improvement in Li+ intercalation and de-intercalation.
