“…This is mainly due to the unique structure of LFP/rGO-300 composite materials. As shown in Table S1, the Li-ion storage of the LFP/rGO-300 composite is better than or comparable to other LFP-based electrodes in previous literature reports [8,10,12,13,17,19,[54][55][56][57][58][59][60][61][62][63][64][65][66][67]. The layered rGO matrix and carbon coating ensure the high structural stability and electrical conductivity of the composite material.…”

Recently, the application of LiFePO4 (LFP) batteries in electric vehicles has attracted extensive attention from researchers. This work presents a composite of LFP particles trapped in reduced graphene oxide (rGO) nanosheets obtained through the high-temperature reduction strategy. The obtained LiFePO4/rGO composites indicate spherical morphology and uniform particles. As to the structure mode of the composite, LFP distributes in the interlayer structure of rGO, and the rGO evenly covers the surface of the particles. The LFP/rGO cathodes demonstrate a reversible specific capacity of 165 mA h g−1 and high coulombic efficiency at 0.2 C, excellent rate capacity (up to 10 C), outstanding long-term cycling stability (98%) after 1000 cycles at 5 C. The combined high electron conductivity of the layered rGO coating and uniform LFP particles contribute to the remarkable electrochemical performance of the LFP/rGO composite. The unique LFP/rGO cathode provides a potential application in high-power lithium-ion batteries.

“…To meet the growing demand of critical metals in LiFePO 4 and NCM, a series of metal-rich mining and metallurgical wastes have been used to fabricate these cathode materials. Steel slag [28], titanium dioxide slag [52], Fe-P waste slag [53], chelate slag [54], vanadium-bearing slag FeSO 4 •7H 2 O [55], waste slag [56,57], extracted vanadium residue [58], and lithium extraction slag [59] are favorable precursors for LiFePO 4 /NCM-based cathode materials. For instance, Yang et al developed a phosphoric acid mixture selective leaching technique to selectively remove impurity elements (e.g., Mn, Cu, and Ni) from lithium extraction slag, and the recovered FePO 4 (R-FePO 4 ) can be directly used as a battery-grade cathode material [59].…”

Developing cost-effective electroactive materials for advanced energy devices is vital for the sustainable development of electrochemical energy conversion/storage systems. To reduce the fabrication cost of electroactive materials (electrocatalysts and electrodes), growing attention has been paid to low-cost precursors. Recently, mining and metallurgical waste has been used to design electroactive materials, which shows great economic and environmental benefits. Herein, current achievements in the applications of mining and metallurgical waste-derived electroactive materials in sustainable energy conversion/storage fields (batteries, supercapacitors, fuel cells, and small-molecule electro-conversion) are comprehensively analyzed. The waste-to-materials conversion methods and materials’ structure–performance relationships are emphasized. In addition, perspectives related to the further development and applications of waste-derived high-performance electroactive materials are pointed out.
