Abstract

A potential cathode material for lithium ion batteries has been developed using a boron polyanion substituted lithium iron manganese phosphate, LiFe<inf>0.4</inf>Mn<inf>0.6</inf>(PO<inf>4</inf>)<inf>1 - x</inf>(BO<inf>3</inf>)<inf>x</inf> (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<inf>0.4</inf>Mn<inf>0.6</inf>(PO<inf>4</inf>)<inf>1 - x</inf>(BO<inf>3</inf>)<inf>x</inf> 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<inf>0.4</inf>Mn<inf>0.6</inf>PO<inf>4</inf>. Among several LiFe<inf>0.4</inf>Mn<inf>0.6</inf>(PO<inf>4</inf>)<inf>1 - x</inf>(BO<inf>3</inf>)<inf>x</inf> samples, LiFe<inf>0.4</inf>Mn<inf>0.6</inf>(PO<inf>4</inf>)<inf>0.995</inf>(BO<inf>3</inf>)<inf>0.005</inf> demonstrated the best cycleability, exhibiting an initial discharge capacity of 159.4 mAh g<sup>- 1</sup> at 0.1 C and 113 mAh g<sup>- 1</sup> at 3 C. LiFe<inf>0.4</inf>Mn<inf>0.6</inf>(PO<inf>4</inf>)<inf>1 - x</inf>(BO<inf>3</inf>)<inf>x</inf> demonstrates enhanced electrochemical properties with excellent reversible cycling via boron polyanion substitution.
