Synthesis and characterization of a novel electrolyte based on bis[(perfluoroalkyl)sulfonyl]triimide trianion

Metal- and covalent-organic frameworks as solid-state electrolytes for metal-ion batteries

“…Such electrolytes still possess an advantageously high density of anionic hopping sites and the safety features of solid electrolytes, but obtaining higher metal cation transference numbers will likely be a challenge due to the large percentage of mobile anions. An interesting extension upon this work could involve soaking the COF in a polylithium salt [63][64][65][66][67]. This could yield the COF with equal equivalents of the polyanion immobilized within the channels, triaminoguanidinium groups within the framework itself and mobile Li + .…”

Electrochemical analysis of diffusion behavior and nucleation mechanism for neodymium complex in potassium bis(trifluoromethylsulfonyl)amide melts

“…2, SD curve (chain line) was also obtained from the voltammogram by SD method. 26 5 The value of W p ; the width of a derivative neopolarographic peak at half its height, and e p ; the 1 current semi-derivative at the peak of the derivative neopolarogram, were determined from the SD 2 curve. The diffusion coefficients were calculated using the following equations [15] that were 3 established in the case of the irreversible reaction: 4…”

Synthesis and Application of a Conjugated Polydianion‐Based Single‐Ion Conducting Polymer for High‐Performance Solid Lithium‐Ion Batteries

“…Importantly, Li/PEO‐LiPFSDI‐20/stainless‐steel cell is stable up to 6 V versus Li + /Li, which is higher than the 5.5 V for Li/PEO‐LiPFSI‐20 stainless‐steel cell . The high oxidation potential of imide salts with conjugated polydianion was also reflected in the study of a tri‐imide sodium salt by Nie . At high potential, the stability of electrolytes is determined by anions immobilized in the polymeric backbone for SLICPs.…”

“…[47] The high oxidation potential of imide salts with conjugated polydianion was also reflected in the study of a triimide sodium salt by Nie. [52] At high potential, the stability of electrolytes is determined by anions immobilized in the polymeric backbone for SLICPs. As only the anions at the interface of the electrodes can lose their negative charge, both PEO-LiPFSDI-20 and PEO-LiPFSI-20 electrolytes exhibit better electrochemical stability than PEO-LiTFSI-20.…”
