Summary: Poly(triazine imide) photocatalysts prepared via molten salt methods show promise as polymer semiconductors with one-step excitation capacity for overall water splitting. This study focuses on understanding the molecular conjugation, nucleation, and crystallization processes of PTI crystals to enable controllable structure design. The research reveals that the heptazine-based precursor depolymerizes to triazine monomers within molten salts, and the KCl cubes act as leading cores that guide the directional stacking of PTI molecular units to form aggregated crystals. By tailoring the crystallization fronts, PTI crystals with improved dispersibility and enhanced photocatalytic performance are obtained, advancing the understanding and development of ordered condensation of polymer crystals.

Summary: A novel bifunctional electrolyte additive, NFSI, was developed to greatly improve the cyclability and safety of lithium metal batteries. NFSI preferentially reacts with the lithium anode to form a stable solid electrolyte interphase (SEI) film, inhibiting electrolyte consumption and lithium dendrite growth. Additionally, NFSI is preferentially oxidized to form a conductive thin film layer. Li||Li cells containing 0.1 M NFSI exhibit excellent cycle stability and Li||Cu cells show high Coulombic efficiency.

Summary: In this study, the use of fluorinated sulfonamide as a solvent and the incorporation of lithium (fluorosulfonyl)(n-nonafluorobutanesulfonyl)imide as a co-salt and/or electrolyte additive were proposed to achieve safer and high-performing rechargeable lithium metal batteries. The sulfonamide-based electrolytes exhibited excellent flame-retardant abilities and good ionic conductivity. The addition of lithium (fluorosulfonyl)(n-nonafluorobutanesulfonyl)imide effectively suppressed side reactions at the cathode compartment, stabilizing the lithium cobalt oxide cathode. This study is expected to provide insights into the working mechanism of lithium (fluorosulfonyl)(n-nonafluorobutanesulfonyl)imide in sulfonamide-based electrolytes and promote the development of high-energy and safer rechargeable lithium metal batteries.

Summary: Polymeric solid-state electrolytes composed of lithium hydroxide (LiOH) and branched-poly(ethyleneimine) (bPEI) were used to fabricate lithium polymer supercapacitors (LPSCs) with stable charging/discharging characteristics. The highest energy density of LPSCs was obtained with LiOH = 90 mol% due to the highest ion conductivity. The optimized LPSCs with bPEI:LiOH solid-state electrolytes (LiOH = 90 mol%) retained approximately 85% of their capacity after 700 cycles.

Summary: Despite the significant improvement in the performance of all-solid-state batteries in recent decades, the lack of understanding of their working mechanism remains a hindrance in many studies and in enhancing the properties and performance of solid polymer electrolytes (SPE). Molecular dynamics simulations were conducted to investigate the solvation structure in concentrated poly (ethylene carbonate) (PEC) electrolytes and to enhance their ionic conduction. The competitive effect induced by the interactions between Li cations and TFSI anions was found to replace the main coordination of C=O groups in PEC chains and enhance segmental motion. The calculations of total coordination number in the electrolytes indicated that the release of Li cations from the coordinating bonds would increase the transport number with the increase in salt concentration.

Summary: The low concentration electrolyte with the addition of LiFSI and potentiostatic reduction pre-treatment at a low potential shows improved electrochemical performance. The reduction of LiFSI facilitates the formation of a LiF-rich cathode-electrolyte interphase (CEI) on the cathode surface, enhancing the cycle stability of the cathode. Compared to traditional electrolyte engineering strategies, this method requires lower reaction energy and potential. It provides an effective way to improve the performance of low concentration electrolytes by constructing a LiF-rich CEI.
