Special Issue Information

Dear Colleagues,

All-solid-state batteries (ASSBs) have attracted intensive research interest and show promising potential as the next-generation of energy storage devices for electric vehicles (EVs). Compared to conventional liquid-based batteries, using solid-state electrolytes (SSEs) in ASSBs offers high energy densities without compromising safety, therefore providing great opportunities to meet the growing demands of long-range EVs. However, the development of ASSBs is at the initial stage and faces significant challenges, such as low ion conductivity of SSEs, chemical/electrochemical unstable toward cathode and anode materials, and big gaps for large-scale indusial production. Therefore, in-depth mechanism studies are essential to realizing high-performance ASSBs. Advanced characterization techniques provide insights into the battery materials’ working/failure mechanisms and therefore give valuable guidance to the design of future ASSBs. Therefore, this Special Issue aims to cover the latest research progress on the advanced characterizations applied in ASSBs. All article types permitted by Batteries are welcome.

Potential topics include, but are not limited to, the following:

  • Mechanism studies on solid-state electrolytes;
  • Failure analysis on cathode and anode interfaces;
  • New characterization techniques in solid-state batteries;
  • Calculation, machine learning, and artificial intelligence in battery research.

Abstract
Metal halide solid-state electrolytes (SSEs) (Li-M-X system, typically Li3MX6 and Li2MX4; M is metal or rare-earth element, X is halogen) exhibit significant potential in all solid-state batteries (ASSB) due to wide stability windows (0.36–6.71 V vs. Li/Li [...] Read more.
Metal halide solid-state electrolytes (SSEs) (Li-M-X system, typically Li3MX6 and Li2MX4; M is metal or rare-earth element, X is halogen) exhibit significant potential in all solid-state batteries (ASSB) due to wide stability windows (0.36–6.71 V vs. Li/Li+), excellent compatibility with cathodes, and a water-mediated facile synthesis route for large-scale fabrication. Understanding the dynamics of Li+ transportation and the influence of the host lattice is the prerequisite for developing advanced Metal halide SSEs. Neutron powder diffraction (NPD), as the most cutting-edge technology, could essentially reflect the nuclear density map to determine the whole crystal structure. Through NPD, the Li+ distribution and occupation are clearly revealed for transport pathway analysis, and the influence of the host ion lattice on Li+ migration could be discussed. In this review, we stress NPD utilization in metal halide SSEs systems in terms of defect chemistry, phase transition, cation/anion disorder effects, dual halogen, lattice dynamics/polarizability, and in situ analysis of phase evolution. The irreplaceable role of NPD technology in designing metal halide SSEs with enhanced properties is stressed, and a perspective on future developments of NPD in metal halide SSEs is also presented.
