Synthesis, application and industrialization of LiFSI: A review and perspective

Design Criteria of Dilute Ether Electrolytes toward Reversible and Fast Intercalation Chemistry of Graphite Anode in Li-Ion Batteries

“…Second, the frontier orbital is on FSI – rather than DOL by using LiFSI instead of LiTFSI. Third, S–F bond cleavage is facile, and FSI – undergoes more complete reduction compared to TFSI – . , Besides, the potential of SEI formation should be higher than the potential where the cointercalation takes place. To probe the formation process, we collected potentiostatic intermittent titration technique (PITT) data (Figure S24), in which a higher reduction potential is seen in CIP-dominated 1 M LiFSI DOL compared to the SSIP-dominated 1 M LiFSI DME. , In 1 M LiFSI DOL, when the fresh cell was held at 1.18 V, a peak suggestive of SEI nucleation and growth by FSI – reduction was observed .…”

Recent status, key strategies and challenging perspectives of fast-charging graphite anodes for lithium-ion batteries

“…Owing to their elevated ionic conductivity and Energy & Environmental Science Review reduced fluorine content, LiFSI-based electrolytes are regarded as a potential alternative to conventional LiPF 6 -based electrolytes, and have attracted great interest particularly in the field of fast-charging batteries. [235][236][237] This provides an important reference for the selection of electrolytes with high conductivity for fast-charging graphite anodes.…”

Oxygen-deficient TiO2−x interlayer enabling Li-rich Mn-based layered oxide cathodes with enhanced reversible capacity and cyclability

“…Lithium-ion batteries (LIBs) have gained increasing attention as efficient and clean energy storage devices to reduce the carbon dioxide emissions from fossil fuels, restraining environmental pollution, 1 and thus the related LIB industry has developed rapidly. 2,3 To date, LIBs have been widely applied in portable electronic devices, power tools, medical devices, smart watches, satellites, drones, marine vehicles, electric vehicles and utilityscale storage. However, the expanding applications of LIBs has also increased the battery requirements including higher energy density, longer life, lower cost, and safer features.…”
