Advances in understanding and regulation of sulfur conversion processes in metal–sulfur batteries

Abstract

Lithium-sulfur batteries (LSBs) have attracted intensive attention as a promising next-generation energy storage system, due to the high energy density and low cost of sulfur cathodes. Despite the substantial progress...

Recent advances in proton exchange membrane water electrolysis

“…Artificial intelligence (AI), DFT, and high-throughput screening technologies are helpful to examine, analyze and interpret experimental results. High-throughput computational/experimental databases coupled with AI can predict virtual materials with ideal properties to satisfy specific requirements in electrochemical systems such as metal–sulfur batteries, 278 calcium rechargeable batteries, 279 and catalysts. 280 As such, material exploration can be significantly accelerated.…”

Two birds with one stone: engineering siloxane-based electrolytes for high-performance lithium–sulfur polyacrylonitrile batteries

“…31 As a result, Li‖SPAN full cells delivered remarkable cyclic stability with impressive CEs close to 100% in conventional carbonate electrolytes due to the solid-solid conversion mechanism with negligible polysulde dissolution. 32,33 However, it is noteworthy that the excessive use of Li articially prolongs battery lifespan. The poor Li reversibility (<95%) and severe Li dendrite growth in conventional carbonate electrolytes lead to potential safety hazards, which should not be ignored (Fig.…”

Visualizing the Interfacial Chemistry in Multivalent Metal Anodes by Transmission Electron Microscopy

“…For example, X‐ray diffraction (XRD) is employed to detect the crystallographic information, while the chemical compositions are revealed by X‐ray photoelectron spectrometry (XPS), nuclear magnetic resonance (NMR), Fourier transform infrared spectroscopy (FTIR) and Raman spectroscopy. [ 12 ‐– 14 ] However, these characterization techniques mainly reported the averaged data instead of the local structural information. In addition, SEI or interphase layers are metastable and sensitive to air and electron/laser beams during ex situ characterizations.…”
