Figure 4. (A) This diagram delineates the procedural evolution of the surface topography and nitrogen incorporation within the carbon-encapsulated LiMn_0.8Fe_0.2PO₄/C composite, complemented by its attendant cycling performance data^[87].

Furthermore, the diagram also includes an evaluation of the rate capabilities at an ambient temperature of 25 °C, alongside the computed total density of states (TDOS) for a spectrum of materials, namely diamond, graphene, B/P-modified diamond, and B/P-modified graphene, each predicated on their distinct structural frameworks^[88].
