Deep eutectic solvents (DESs) are increasingly recognized as viable environmentally friendly alternatives to traditional organic because of their low toxicity and exceptional dissolving capabilities. In this research, 12 DESs were synthesized systematically integrated with ultrasonic-assisted extraction (UAE) extract flavonoids from Scutellaria Radix. Comprehensive screening revealed that the optimal DES outperformed conventional (water 70 % ethanol) in efficiency. Through statistical...

Abstract Fluorosulfonimide lithium salts have been widely used as conductors in solid polymer electrolytes for Li‐ion batteries (LIBs). However, low conductivity and poor compatibility with the host (usually polyethylene oxide, PEO) remain challenges design of these salts. In this paper, we synthesized a highly Li + ‐conductive salt containing poly(perfluoroalkylsulfonyl)diimide (PFSDI − ) dianion first time. LiPFSDI represents example single Li‐ion‐conducting (SLICP) conjugated sulfonimide...
