Description |
Novel category LiMnSnO4 compound was synthesized via. Urea assisted combustion (UAC) method at 800 �C and examined for possible
use as cathode material in lithium-ion batteries. The XRD (X-ray diffraction) results of LiMnSnO4 sample authenticate the orthorhombic
crystal structure with high degree of crystallinity. Presence of uniformly distributed nanometric grains (scanning electron
microscopy) with preferred local cation environment is evident from FT IR (Fourier transform infra red spectroscopic) and 7Li
NMR (nuclear magnetic resonance spectroscopy) studies. The charge–discharge behavior of Li/LiMnSnO4 cells demonstrated a specific
capacity of 113 mA h/g, with an excellent capacity retention (95%) and Ah efficiency (>99%). Besides, the internal resistance of the Li/
LiMnSnO4 cell after 30 cycles is negligibly small, thus demonstrating good electronic conductivity and cycling stability, required for any
lithium intercalating cathode material.
