Abstract

Rechargeable lithium-ion batteries have emerged as the dominant energy storage source due to their higher capacity, energy density and excellent cyclability. Graphitic materials are commonly utilized as the anode material for lithium-ion batteries. Silver nanoparticles incorporated vein graphite (SVG) materials were prepared for Li Ion Battery (LIB) applications. The graphite sample was purified by acid leaching, followed by modifying the surface with HNO3. The silver graphite composite material was synthesized using AgNO3 as the precursor and trisodium citrate as the reducing agent. Phase analysis revealed that the silver nanoparticles have been successfully incorporated into the surface of the modified graphite after chemical reduction and mechanical agitation. Half-cell testing was carried out using CR 2032 coin cells with silver vein graphite composite as the active material and 1 M LiPF6 (EC: DMC; vol. 1:1) as the electrolyte at the National Center for Advanced Battery Research in NIFS. Galvanostatic charge-discharge study of the cell with silver vein graphite composite showed an initial charge-discharge Coulombic efficiency of 88.3% and a promising discharge capacity of 373 mAh g-1 in the voltage range of 0.002 - 1.5V at C/10 rate. Overall, the electrochemical performance of our developed nanostructured silver particles incorporated vein graphite anode shows a noticeable improvement of the reversible capacity, Coulombic efficiency and cycling behaviour.
