Special Issue Information

Dear Colleagues,

Solid electrolyte interphase (SEI) is key to the durability of lithium-based batteries and is also relevant for multi-valent batteries beyond lithium-ion. Its stability is of paramount significance in ensuring the efficient operation of batteries, especially in demanding environments such as those encountered in electric vehicles and high-capacity stationary storage systems. An unstable SEI can lead to rapid battery degradation, capacity loss, and potential safety concerns. Thus, enhancing our understanding and knowledge of the SEI stability can revolutionize the battery domain.

In this Special Issue of Batteries, ‘Advancements in Electrode–Electrolyte Interface: From Lithium-Ion to Multi-Valent Batteries’, our primary focus will be on the stability of the SEI. We aim to delve deep into the factors affecting its stability, methods to characterize it, and innovative solutions to enhance it.

We are particularly interested in contributions that address the following:

  • Explore the chemical and physical formation mechanisms of SEI and their impact on its stability;
  • Understand the effects of different electrolyte compositions, additives, and solvents on SEI stability;
  • Investigate the influence of battery operation conditions, such as temperature, state of charge, and charge/discharge rates on SEI evolution and stability;
  • Develop state-of-the-art characterization techniques to monitor SEI growth, thickness, and composition both in situ and ex situ;
  • Propose novel strategies, materials, or formulations to enhance SEI stability and reduce its impedance growth;
  • Understand and mitigate the side reactions leading to SEI instability and consequential lithium-ion battery capacity loss;
  • Link SEI stability with the overall safety, thermal behavior, and potential hazards in multi-valent and lithium-ion cells.

Topics of interest include but are not limited to the following:

  • Advanced spectroscopic and microscopic techniques for SEI characterization;
  • The role of electrolyte additives in SEI stability;
  • Computational and theoretical studies on SEI formation and evolution;
  • Impact of SEI instability on overall battery degradation and failure mechanisms;
  • Innovations in SEI protective coatings and barrier layers;
  • Electrochemical techniques to evaluate SEI properties and its influence on battery performance;
  • Correlation between SEI stability and lithium plating in fast charging conditions;
  • SEI's role in preventing or aggravating dendritic growth;
  • Influence of SEI on solid-state lithium batteries and next-generation chemistries.

We believe that by highlighting the intricacies of the solid electrolyte interphase and its stability, this Special Issue will act as a beacon for researchers, academicians, and industry experts, propelling them towards the development of more reliable, long-lasting, and safer multi-valent and lithium-ion batteries.

This study explores the potential of titanium disulfide (TiS2) as an active material for aqueous calcium-ion batteries (CIBs). We investigate the electrochemical redox reactions of calcium ions within TiS2 and assess its suitability for use in aqueous CIBs. Additionally, we examine the impact of varying electrolyte concentrations, ranging from 1.0 to 8.0 mol dm−3, on TiS2 electrode reactions. Our findings reveal that TiS2 exhibits distinct charge–discharge behaviors in various aqueous calcium-ion electrolytes. Notably, at higher electrolyte concentrations, TiS2 effectively suppresses the hydrogen generation reaction caused by water decomposition. In situ X-ray diffraction analysis confirms the intercalation of Ca2+ ions between the TiS2 layers during charging, which is a groundbreaking discovery, signifying TiS2’s applicability in aqueous CIBs. X-ray photoelectron spectroscopy analysis further supports the formation of a solid electrolyte interphase (SEI) on the TiS2 electrode surface, contributing to the suppression of electrolyte decomposition reactions. Furthermore, we investigate the influence of anions in the electrolyte on charge–discharge behavior. Our findings suggest that the choice of anion coordinated with Ca2+ ions affects the SEI formation and cycling performance. Understanding the role of anions in SEI formation is crucial for optimizing aqueous CIBs. In conclusion, this research underscores TiS2’s potential as an active material for aqueous calcium-ion batteries and emphasizes the importance of the electrolyte composition in influencing SEI formation and battery performance, contributing to sustainable and efficient energy storage technologies.
