Special Issue Information

Dear Colleagues,

The electrode/electrolyte interface is the forefront where chemical and electrochemical reactions occur within battery systems. Although tremendous efforts have been invested in advancing knowledge, the electrode/electrolyte interface, including the solid/electrolyte interface (SEI) and cathode/electrolyte interface (CEI), is still poorly understood, mainly due to its complex composition and nanometer-scale structure as well as a lack of suitable probing techniques.

The interfacial properties (e.g., chemical composition, structure, and physicochemical properties) and the interfacial electrochemical dynamics are crucial, as they dictate a series of macroscopic performances of batteries, including dis/charge capacity, rate performance, operation stability, and safety. Understanding the interfacial properties and interfacial electrochemical behaviors, and developing optimization strategies, are thus paramount, as they could promote an in-depth and comprehensive understanding and, more importantly, accelerate the design and development of advanced batteries with superior performance.

This Special Issue focuses on understanding the electrode/electrolyte interfacial properties and interfacial dynamics as well as developing optimization strategies in various battery systems.

Topics of interest include, but are not limited to:

  • advanced interfacial characterization
  • solid/solid or solid/liquid interface
  • interfacial chemistry, structure, or physicochemical properties
  • interfacial dynamics and kinetics
  • theoretical calculations and modeling

Potential battery systems include but are not limited to:

  • Li/Na/K/Mg/Zn ion and metal batteries
  • metal–sulfur batteries
  • metal–air batteries
  • solid-state batteries
  • polymer batteries
  • aqueous batteries
  • redox flow batteries

Irreversible phase transition caused capacity fading has been considered as an obstacle for rechargeable batteries. An in-depth investigation of the irreversible phase transition is critical for understanding the reaction mechanism and developing advanced batteries. In this work, taking vanadium oxide and its alkali ion-stabilized intercalation compounds (A-V-O, A = Li, Na, K) as prototypes, utilizing operando characterizations, we discovered coupled discontinuous (interlayer)-continuous (intralayer) transitions in the stabilized multielectron intercalation cathodes. The highly ordered crystal of vanadium pentoxide irreversibly transfers to a disordered/amorphous structure after the first cycle, whereas A-V-O enables reversible discontinuous lattice transitions at the interlayer pathway for facilitating lithium diffusion. Among the A-V-O family, K-V-O, with the highest capacity retention, shows a coupled discontinuous-continuous transition, which exhibits a continuous transition and the minimum volume change at the V-O intralayer during lithium intercalation/deintercalation. These coupled discontinuous-continuous lattice transitions were captured for the first time in cathode materials. It implies that the suitable ion intercalation induced continuous intralayer transition inhibits the irreversible ion intercalation and phase transition. Full article
