The paper summarizes results of substantiating, selecting, developing, manufacturing and testing of oxidic multicomponent surface compositions with the perovskite structure on porous titanium matrixes proposed for use in anodes of low-temperature electrochemical systems with a liquid electrolyte. Electrochemical activity of 88 oxide layers was evaluated as a function of composition, concentration and temperature of the carbonate electrolyte, elementary content of oxidic composition, and physical/chemical characteristics of the crystal structure. It was shown that the electrode process can be controlled by changing components of the electrolyte or complexity of the multicomponent oxidic surface compositions.

Revitalizing interphase in all-solid-state Li metal batteries by electrophile reduction.

All-solid-state lithium metal batteries promise high levels of safety and energy density, but their practical realization is limited by low Li reversibility, limited cell loading and demand for high-temperature and high-pressure operation, stemming from solid-state electrolyte (SSE) low-voltage reduction and high-voltage decomposition, and from lithium dendrite growth. Here we concurrently address these challenges by reporting that a family of reductive electrophiles gain electrons and cations from metal-nucleophile materials (here a Li sulfide SSE) upon contact to undergo electrochemical reduction and form interphase layers (named solid reductive-electrophile interphase) on material surfaces. The solid reductive-electrophile interphase is electron blocking and lithiophobic, prevents SSE reduction, suppresses Li dendrites and supports high-voltage cathodes.

Recently, photo-assisted electrocatalysis as an emerging catalytic approach that combines the technologies of photocatalysis and electrocatalysis has attracted great interest among researchers. Under this circumstance, the NiFe-LDH compounded with PbS based (PbS@NFHS) heterojunction with both photoactive and electrocatalytic properties was constructed for the first time through an ambient etching route and a subsequent low-temperature hydrothermal method. The as-prepared catalyst displayed a novel hierarchical 3D open structure based on nanosheets, which offered numerous electrochemically active sites, facilitated the swift diffusion of ions and enhanced both electrical conductivity and catalytic stability, thus significantly improving the catalytic performance.

Silicon (Si) is recognized as a promising anode material for lithium-ion batteries (LIBs). However, the significant volume expansion during lithiation poses a make-or-break challenge for the commercial adoption of silicon as an anode. The solutions to mitigate the challenge often depend on processes that can increase costs for the LIB.

Room-temperature sodium-sulfur (RT Na-S) batteries, known for their high-energy density, low cost and environmental friendliness, have attracted much attention. However, the development of RT Na-S batteries has encountered a number of challenges, including low conductivity and large volume changes of sulfur during the charge-discharge cycles. In this study, TiO nanoparticles modified porous carbon hosts for sulfur in RT Na-S batteries were prepared by a simple and efficient spray drying method combined with solution immersion.

Carbon coating on SiO surface is crucial for enhancing initial Coulombic efficiency (ICE) and cycling performance in batteries, while also buffering volume expansion. Despite its market prevalence, the effects of the carbon layer's quality and structure on the electrochemical properties of SiO remain underexplored. This study compares carbon layers produced via gas-phase and solid-phase coating methods, introducing an innovative technique that sequentially uses two gases to develop a low-impedance hybrid carbon structure.
