In this project, we studied the effect that carbon coating with graphene has on the performance of Li2Fe0.5Mn0.5SiO4 cathode materials for lithium-ion batteries. We synthesized the Li2Fe0.5Mn0.5SiO4 cathode materials, tested the performance with coin-cell battery testing, and characterized the composites through SEM and XRD analysis. Results are promising, indicating improved discharge capacity of the batteries and exceptional current efficiency, making grapheme-coated Li2Fe0.5Mn0.5SiO4 cathode materials a significant advance in energy storage.
