Inorganic Electrode Materials in High-Performance Energy Storage Devices

This Reprint focuses on the innovation, optimization, and application of inorganic electrode materials for high-performance energy storage, addressing key challenges in advanced energy storage technologies. It covers a diverse range of systems, including lithium–sulfur batteries, lithium-ion batteries, aqueous zinc-ion batteries, sodium-ion batteries, hybrid supercapacitors, and methanol-mediated water splitting. Featured research highlights cutting-edge strategies: structural engineering (hollow architectures, carbon nanofiber encapsulation, porous nanosheets), composition regulation (bimetallic synergistic effects, heteroatom doping, high-entropy alloying), and simplified scalable synthesis (EDTA-based synchronous carbonization–doping, two-step thermal annealing). The collected works report remarkable performance breakthroughs—such as long-cycle stability for sodium-ion battery anodes, high-rate capability for lithium-ion battery electrodes, and low overpotential for water-splitting catalysts—while elucidating critical structure–performance relationships. This Reprint serves as a concise, authoritative resource for researchers and engineers, facilitating knowledge exchange on inorganic electrode materials and accelerating the translation of fundamental research into practical, sustainable energy storage solutions.
