LiMnxFe1–xPO4 (LMFP, 0 < x < 1) suffers from low electronic conductivity and Mn dissolution. Reduced graphene oxide (rGO) improves electronic conductivity and acts as a sacrificial oxygen source, enabling conformal CEI formation via oxidation of surface functional groups, thereby enhancing interfacial stability and cycling performance of LMFP electrodes.
