However, the widespread application of ultra-high nickel-layered cathodes still suffers limitation by structural instability and poor rate performance. Herein, a crystal-face-induced strategy is proposed to enhance rate and cycling performances of the electrode by constructing rapid Li<sup>+</sup> diffusion channel and reducing internal grain boundaries of secondary particles. The crystal-face-induced strategy facilitates the growth of {010} lattice plane. Highly exposed {010} planes provide wide-open and unobstructed channels for Li<sup>+</sup> deintercalation/intercalation, enhances the electrode diffusion kinetics, and thus improves the electrode rate performance. In addition, this strategy promotes the primary particle growth, reduces the grain boundaries of secondary particles and mitigates the electrode/electrolyte interface side reactions, enhancing the structural stability and cycling life of the electrode. Accordingly, the modified sample achieved a reversible specific capacity of 198.3 mAh g<sup>−1</sup> at 1 C (1 C = 180 mA g<sup>−1</sup>) and maintained a capacity retention rate of 88.5 % after 100 cycles, higher than that of the original sample (73.6 %, 146 mAh g<sup>−1</sup>). At the high rate of 5 C, it can maintain a high specific capacity of 178 mAh g<sup>−1</sup> (capacity retention rate of 99 %) after 150 cycles.

Herein, a synergistic strategy of surface-induced spinel structure and F doping is provided to improve the structural stability. The surface spinel structure helps to reduce the structural collapse caused by electrolyte corrosion on the cathode and effectively inhibits voltage decay resulted from structural evolution. The stronger Mn-F bonds are formed by F doping to inhibit migration of transition metal (TM) and induce the uniform deposition of LiF to form the thinner and more stable CEI on the cathode. Accordingly, the designed cathode (LMNO-NF) shows remarkable cycling performance with the capacity retention of 86.68 % and voltage retention of 96.6 % for 200 cycles at 1C, higher than pristine material (68.76 % and 85.75 %).

The paper presents an overview of the present state of coal gangue production and utilization, and investigates the environmental impact caused by the practice of stacking coal gangue. We emphasize the current research status of gangue in various high-value application fields, including environmental materials, agricultural production, construction materials, recovery and extraction of valuable elements, and energy generation. It highlights the significance of pre-treatment methods like activation, modification, and innocuousness for the comprehensive utilization of gangue. Additionally, we briefly introduce and discusses the future directions of research and development in this area. Nevertheless, with regard to the environmental impact of secondary contamination and the efficiency of gangue utilization, there remain numerous obstacles and unresolved matters that merit further investigation.
