“…Notably, ALD has emerged as a particularly promising technique for electrode surface modification, significantly reducing direct electrode/electrolyte contact, thereby minimizing side reactions and substantially prolonging the cycle life [ 40 ]. Aluminum oxide (Al 2 O 3 ) has emerged as the predominant coating material in numerous studies, owing to its extensive application in both academic research and industrial settings [ 42 , 43 ]. Therefore, the design of a 2D flake-like CuO structure combined with an ultrathin conformal Al 2 O 3 coating layer could be a promising strategy for achieving desirable sodium storage.…”

CuO is recognized as a promising anode material for sodium-ion batteries because of its impressive theoretical capacity of 674 mAh g−1, derived from its multiple electron transfer capabilities. However, its practical application is hindered by slow reaction kinetics and rapid capacity loss caused by side reactions during discharge/charge cycles. In this work, we introduce an innovative approach to fabricating large-area CuO and CuO@Al2O3 flakes through a combination of magnetron sputtering, thermal oxidation, and atomic layer deposition techniques. The resultant 2D CuO flakes demonstrate excellent electrochemical properties with a high initial reversible specific capacity of 487 mAh g−1 and good cycling stability, which are attributable to their unique architectures and superior structural durability. Furthermore, when these CuO flakes are coated with an ultrathin Al2O3 layer, the integration of the 2D structures with outer nanocoating leads to significantly enhanced electrochemical properties. Notably, even after 70 rate testing cycles, the CuO@Al2O3 materials maintain a high capacity of 525 mAh g−1 at a current density of 50 mA g−1. Remarkably, at a higher current density of 2000 mA g−1, these materials still achieve a capacity of 220 mAh g−1. Moreover, after 200 cycles at a current density of 200 mA g−1, a high charge capacity of 319 mAh g−1 is sustained. In addition, a full cell consisting of a CuO@Al2O3 anode and a NaNi1/3Fe1/3Mn1/3O2 cathode is investigated, showcasing remarkable cycling performance. Our findings underscore the potential of these innovative flake-like architectures as electrode materials in high-performance sodium-ion batteries, paving the way for advancements in energy storage technologies.

“…For this purpose, techniques such as atomic layer deposition (ALD), pulse laser deposition (PLD), thermal evaporation, or sputtering techniques can find use in the preparation of coatings for Li/Na ion batteries [12]. Among these techniques, ALD has proven capable of preparing ultrathin TiO 2 and Al 2 O 3 artificial SEI layers and increasing the cycling lifetime of Li ion batteries [13,14]. Other materials, such as metal diselenide and functional coatings based on these materials, have shown perspective utilized as an anode electrode for Li ion batteries [15] and stabilizing coatings for high-voltage lithium-ion battery cathodes [16].…”

With the increasing demand for low-cost and environmentally friendly energy, the application of rechargeable lithium-ion batteries (LIBs) as reliable energy storage devices in electric cars, portable electronic devices and space satellites is on the rise. Therefore, extensive and continuous research on new materials and fabrication methods is required to achieve the desired enhancement in their electrochemical performance. Battery active components, including the cathode, anode, electrolyte, and separator, play an important role in LIB functionality. The major problem of LIBs is the degradation of the electrolyte and electrode materials and their components during the charge‒discharge process. Atomic layer deposition (ALD) is considered a promising coating technology to deposit uniform, ultrathin films at the atomic level with controllable thickness and composition. Various metal films can be deposited on the surface of active electrodes and solid electrolyte materials to tailor and generate a protective layer at the electrode interface. In addition, synthesis of microbatteries and novel nanocomplexes of the cathode, anode, and solid-state electrolyte to enhance the battery performance can all be attained by ALD. Therefore, the ALD technique has great potential to revolutionize the future of the battery industry. This review article provides a comprehensive foundation of the current state of ALD in synthesizing and developing LIB active components. Additionally, new trends and future expectations for the further development of next-generation LIBs via ALD are reported. Graphical Abstract
