The slow redox kinetics of polysulfides and the difficulties in decomposition Li2S during charge discharge processes are two serious obstacles to practical application lithium-sulfur batteries. Herein, we construct Fe-Co diatomic catalytic materials supported by hollow carbon spheres achieve high-efficiency catalysis for conversion simultaneously. Fe atom center is beneficial accelerate reaction process, Co favorable charging process. Theoretical calculations combined with experiments reveal...
High emission of carbon dioxide (CO
Lithium metal battery (LMB) technology is very attractive as it has the potential to offer energy densities greater than 1000 Wh L −1 . A thorough investigation of cell performance against various vehicle operational requirements required for successful deployment this in practical electric applications. For instance, there have been several reports on high reactivity Li with electrolyte leading continuous consumption LMB. Due these parasitic reactions, dries out and morphological changes...
A novel synergistic strategy to improve electrochemical performance of Li-rich cathode by co-doping magnesium and aluminium.
Lithium bis(fluorosulfonyl)imide (LiFSI) is a promising replacement for lithium hexafluorosphate due to its excellent properties. A solution the corrosion of aluminum (Al) current collectors by LiFSI at elevated temperatures essential. The mechanisms Al in LiFSI-based electrolyte 45 °C were studied with density functional theory calculations and spectroscopic investigations. It found that irregular, loose unprotected AlF3 materials caused dissolution co-generated Al(FSI)3 can exacerbate...
Inorganic/organic composite passivation film can significantly improve the corrosion resistance performance of hot-dip Al-Zn-coated steel. However, yellowing always leads to obvious degradation in resistance. Investigating mechanism and its impact on would provide a foundation for enhancing property. This study primarily focuses based copolymer N-vinylpyrrolidone N-vinylcaprolactam. It is found that oxidation semi-carbonization butyramide valeroamide generated by C–N bond cleavage at high...
Abstract The increasing interest in Li–O 2 battery arises from its unparalleled theoretical energy density. Nevertheless, the poor reversibility of cathode reaction and unstable characteristic Li anode hinder further application. To address these issues, a high‐performance sandwich‐structured quasisolid polymer electrolyte (QSPE) is designed to meet requirement both anode. For first time, lithiated Nafion ionomer (Li‐Nafion) introduced into cell separate “catholyte” “anolyte.” Redox mediator...

Li metal anodes are a critical battery technology due to their ability substantially increase the energy density of Li-based batteries. It is well known that pressure greatly impacts performance Li-metal anode. However, precisely how value and distribution affect unclear. Furthermore, solid-electrolyte interphase composition forms under varying distributions remains key parameter for practical lithium anodes. In this work, different were employed by using differently shaped oriented...
Li-rich cathodes have been in considerable attention for their high reversible capacity. However, they serious problems like poor cycling with intense capacity decay and voltage fading, which restrict access to practical applications. In this work, a facile efficient strategy is proposed alleviate these intrinsic issues high-efficiency electrolyte system. This special enables deliver superior integrated performance initial discharge of 301 mAh·g–1, outstanding stability retention 88% at 0.5...
For the existing microgrid line traveling wave protection method, head information of is hard to extract, which probably leads false action or non-action protection. This paper proposes a transient-state method that utilizes cosine similarity time domain voltage identify faults. By deriving expression transient at both ends line, conclusion can be summarized forward one end and backward other non-fault are same wave, while waves fault distinct. Based on this, discrimination achieved by using...
