Enhancement of LiFePO4 (LFP) electrochemical performance through the insertion of coconut shell-derived rGO-like carbon as cathode of Li-ion battery

Effect of Heteroatom Doping on Electrochemical Properties of Olivine LiFePO4 Cathodes for High-Performance Lithium-Ion Batteries

“…The ionic radii of Mn 2+ , Nb 5+ , Mg 2+ , and F − are 0.83 Å, 0.64 Å, 0.72 Å, and 1.33 Å, respectively, compared to O 2− (1.4 Å) and Fe 2+ (0.74 Å). Therefore, Nb 5+ , Mg 2+ , and Mn 2+ can substitute Fe 2+ for diffusion into the octahedral interstices on the LFP surface lattice, while Fˉ can easily replace O 2− in the LFP lattice [ 28 , 29 ]. Furthermore, Tables S1 and S2 exhibit the lattice parameters obtained by structural refinement in Figure 3 .…”

Synthesis of rGO-like materials from local agricultural wastes by microwave treatment followed by pyrolysis

“…Several routs have been utilized to produce rGO/rGO-like materials and composites. For example, routes like CVD [15], hammers method [16], modified hammer's method [17], single step reforming [18], and sol-gel technique with mechanical ultracentrifugation [19], have been reported for such synthesis. Despite the advantages of these routes for production of rGO-like materials, little work has been done for synthesis of rGO like materials using microwave followed by calcination step.…”
