Material-specific electric double layers: reviewing the theory to advance understanding of battery interfaces
Original language description
The interface is a key component in batteries, fundamentally influencing charge distribution, potential profiles, and particle transport behaviors. To describe these interfacial phenomena, various theoretical models have been developed, among which electric double layer (EDL) theory provides critical insights at the nanoscale. However, its application to battery electrode materials has often lacked material-specific distinctions, resulting in conceptual ambiguities. This review aims to systematically classify and compare EDL theories across different electrode materials. Specifically, we categorize electrode materials into high-/low-electron-conductivity electrode materials (HECEMs/LECEMs), reflecting their distinct EDL characteristics. HECEMs (e.g., Li metal) exhibit electron spillover and compact Helmholtz layers, whereas LECEMs (e.g., LiFePO4) form space-charge regions with potential-dependent electronic conductivity. We further analyze how variations in electrode material properties influence interfacial kinetics, beginning with a critical evaluation of classical Poisson-Boltzmann theory. Advanced theoretical approaches and experimental techniques are highlighted for their ability to reveal dynamic EDL restructuring during electrochemical cycling. Current challenges, such as modeling quantum effects at interfaces and the limitations of Operando tools, remain to be addressed. The review concludes by outlining the strategies for advanced EDL exploring, emphasizing material-specific interface design, the integration of quantum-corrected ion transport, and other quantum electronics models. By linking fundamental interfacial principles to electrochemical performance, to guide the development of stable, high-energy-density batteries.
