Lithium-ion battery performance with iron phosphate/ graphite composite anodes: A synergistic approach for advanced energy storage solutions

In this study, a novel anode material for lithium-ion batteries is being developed to advance energy storage technology. The research focusses on integrating various percentages of FePO4, which is known for its high capacity when used as anode active material with traditional graphite to increase capacity of anode electrode. Through a variety of electrochemical and material characterization techniques, the produced anode electrodes have been thoroughly analyzed in order to assess the efficacy of the FePO4/Graphite-based new composite material. Electrochemical assessments show that a FePO4: Graphite = 5:95 wt% composite anode delivers the highest discharge capacity of 435 mAh g-1 with Coulombic efficiency of 95 %; it maintains a discharge capacity of 384 mAh g-1 after 200 cycles at 70 mA g-1, with superior capacity retention and rate performance of 309.4 mAh g-1 at 700 mA g-1 compared to the graphite anode. These results highlight the potential of the FePO4/ Graphite composite as an anode material in improving the performance of lithium-ion batteries, making it a viable option for future energy storage solutions.
