Special Issue Information

Dear Colleagues,

As the global demand for efficient and sustainable energy storage systems escalates, coatings and interface engineering are becoming pivotal in achieving high performance, long-term stability, and safe operation. This Special Issue invites original research and comprehensive reviews on the design, synthesis, characterization, and application of advanced coatings and engineered interfaces for next-generation energy storage systems—including but not limited to lithium-ion and emerging battery chemistries, supercapacitors, metal–air/metal–sulfur systems, and solid-state storage technologies. Key topics encompass novel coating materials for electrodes and separators, surface treatments for enhancing ionic/electronic transport, interface stabilization under cyclic/thermal stress, functional nanocomposite films, in situ/operando characterization of coatings in energy storage contexts, and scalability toward industrial application. By bringing together interdisciplinary contributions from surface science, materials engineering, electrochemistry, and device integration, this collection aims to accelerate the translation of coating-enabled solutions into practical energy storage devices, thereby addressing critical challenges in energy efficiency, durability, and sustainability.

With the wide application of lithium-ion batteries (LIBs), many spent LIBs will face the problem of recycling and treatment in the future. The recycling of valuable substances from battery materials is particularly important. In this paper, the spent LiNi0.5Co0.2Mn0.3O2 (S-NCM523) cathode material from used LIBs was regenerated by using the eutectic lithium salt of Li2CO3/LiOH. The lithium element lost by S-NCM523 was supplemented through solid–liquid contact with the molten lithium salt, restoring the layered structure at high temperatures. The successful repair of the regenerated material was verified by various characterization methods, including the elimination of the rock salt phase and the lower Li+/Ni2+ disorder. This research shows that the regenerated cathode material still has a high specific discharge capacity of 146.8 mAh/g after 100 cycles, with a capacity retention rate of 96.0%. The excellent electrochemical performance of the regenerated material demonstrates the feasibility of directly regenerating spent NCM using the molten salt method. Full article
