Frequency dependent conduction characteristics of mechanochemically synthesized NaSn2F5

Mechanochemistry: opportunities for new and cleaner synthesis

“…[108] Similarly, a series of chlorides KMCl 3 (M = Ti, Cr, Mn, Fe, Co, Ni, Cu and Zn) has been prepared [109] and direct combination of CaF 2 and LaF 3 produced Ca 1-x La x F 2+x . [110] There has also been interest in mechanochemically synthesized halides as fast ion conductors, including NaSn 2 F 5 , [111] RbPbF 3 , [112] and Pb 1-x Sn x F 2 . [113] The range of methods used in the synthesis of LaOF demonstrates a number of possible routes to the mechanochemical introduction fluorine; LaOF has been made by ball milling La 2 O 3 with either PTFE, [114] poly(vinyldene fluoride) [115] or with LaF 3 .…”

Influence of silver ion reduction on electrical modulus parameters of solid polymer electrolyte based on chitosan-silver triflate electrolyte membrane

“…The formation of loss peaks is clearly observed in Figure 4. It is obvious that at lower frequencies M″ exhibits low value, which might be due to the large value of capacitance associated with the electrode polarization effect [26]; as a result of accumulation of a large amount of charge carriers at the electrode/solid polymer electrolyte interface. However, at high frequencies well-defined peaks are observed.…”

Spatial confinement – rapid 2D F−diffusion in micro- and nanocrystalline RbSn2F5

“…52 Within this family RbSn 2 F 5 offers the highest ion conductivity 53 followed by KSn 2 F 5 and NaSn 2 F 5 . 54,55 Up to now it has only been prepared by solid-state reaction 52 or hydrothermal synthesis in aqueous solution as first reported by Donaldson and O'Donoghue in 1964. 56 In 1987 the structure of KSn 2 F 5 , to which RbSn 2 F 5 is isomorphous, was resolved as being trigonal, i.e., crystallizing with the space group P% 3.…”
