Abstract:
Atomic-layer materials (ALMs) provide a promising platform for electrochemical energy storage because their atomically thin structures and interfaces enable control over ion adsorption, charge transfer, diffusion pathways, and interfacial stability. In this review, ALMs include both intrinsic two-dimensional (2D) materials and atomic-layer-engineered functional coatings and interphases produced by atomic layer deposition (ALD), molecular layer deposition (MLD), or related approaches. This work connects atomic-scale design variables, including atomic-scale structural parameters, with device-level performance, degradation, and manufacturability. Their sustainability in batteries and supercapacitors (SCs) will be the main focus. Particular attention is given to how these variables regulate interfacial electrochemical phenomena, metal-ion deposition, and mechanical stability. Artificial intelligence (AI) and machine learning (ML) are discussed as ALM-specific tools for screening and optimizing ALD/MLD coating chemistry and deposition conditions. Although ALMs offer advantages in laboratory results, practical deployment remains limited by techno-economic bottlenecks or industrial scalability barriers for 2D material processing and device integration. Near-term commercialization is promising for high-leverage interfacial-modification functions in batteries and integrated micro-energy-storage devices. This review also provides a manufacturing framework for discussing the development of durable, scalable, and AI-enabled ALM-based energy-storage technologies.
