Abstract

A potential cathode material for lithium ion batteries has been developed using a boron polyanion substituted lithium iron manganese phosphate, LiFe_0.4Mn_0.6(PO₄)_{1 - x}(BO₃)_x (x = 0 to 0.03). Without any external carbon source, the material has been synthesized by solid-state reaction using ball-mill and was subsequently characterized by X-ray diffraction, scanning electron microscopy, electron energy loss spectroscopy, X-ray photoelectron spectroscopy, cyclic voltammetry, and galvanostatic charge-discharge measurement. The LiFe_0.4Mn_0.6(PO₄)_{1 - x}(BO₃)_x samples show a single-phase crystalline nature with X-ray diffraction analysis, and enhanced discharge capacity at various C-rates as compared to that of pure LiFe_0.4Mn_0.6PO₄. Among several LiFe_0.4Mn_0.6(PO₄)_{1 - x}(BO₃)_x samples, LiFe_0.4Mn_0.6(PO₄)_0.995(BO₃)_0.005 demonstrated the best cycleability, exhibiting an initial discharge capacity of 159.4 mAh g^{- 1} at 0.1 C and 113 mAh g^{- 1} at 3 C. LiFe_0.4Mn_0.6(PO₄)_{1 - x}(BO₃)_x demonstrates enhanced electrochemical properties with excellent reversible cycling via boron polyanion substitution.
