The definitive version is published in Materials Research Express, vol. 4(7): https://doi.org/10.1088/2053-1591/aa7829Manganese-doped lithium iron phosphate (LFMP) integrated with reduced graphene oxide (RGO) has been prepared via microwave-assisted synthesis and investigated as lithium-ion energy storage system in aqueous Li2SO4 electrolyte. The doping of the LFP was achieved with a low-cost commercial electrolytic manganese oxide (EMD) precursor using a microwave-assisted solvothermal technique. When compared to the undoped counterpart (LFP/RGO), obtained under similar experimental conditions, the LFMP/RGO nanohybrid showed an improved electrochemical performance. The LFMP/RGO gave a maximum areal capacitance of ca. 39.48 mF cm−2, power density of 70.3 mW cm−2 and energy density of 8 mWh cm−2 compared to the values for the pristine complex (LFP/RGO); ca. 16.85 mF cm−2, 54.4 mW cm−2 and 4.8 mWh cm−2. In addition, when the two types of electrochemical storage systems were subjected to voltage-holding (floating) experiment for 50 h, LFMP/RGO maintained 98% capacitance retention while LFP/G maintained 94% capacitance retention. The findings in this work prove that Mn-doping is capable of enhancing the electrochemical performance of the LFP material for energy storage.enLithium iron phosphateReduced graphene oxideAqueous batteriesElectrochemistryArticleRossouw, C.
