A Soft-Solid Co-Crystalline Electrolyte Combining Advantages of Organics and Ceramics: Thermally, Electrochemically Stable, Highly Conductive (Adiponitrile)2LiPF6

“…In addition, model V also shows that the cocrystals at room temperature possess a liquid-like surface layer (Figure S8b) similar to other soft solid cocrystals 14 , and which is also seen from SEM analysis of this electrolyte (Figure S5 and S6). This nanoliquid surface behavior is a general characteristic of this class of electrolytes 11,12,14,47 . To determine the structure of the intergranular interface, model V8g (surface model) with eight nano-sized grains (1 grain = 5x5x5 unit cells) were simulated in a vacuum box of 30x30x30 nm 3 (Figure 3a).…”

“…Previous work in our group has focused on co-crystals of lithium (or sodium) salts with a coordinating ligand that has "soft" (polarizable), weakly electron-donating atoms, e.g. dimethyl formamide (DMF) with LiCl 11 or NaClO4 12 , isoquinoline with LiCl 13 , or adiponitrile (ADN) with NaClO4 14 , where the weaker binding promotes higher conductivity. Some of these cocrystals melt at moderate temperatures, 12,14 and can therefore be melt-cast, in contrast with inorganic electrolytes, where the grains need to be sintered at high pressures and temperatures.…”

Zinc Battery Driven by an Electro-Organic Reactor Cathode

“…This indicates the conversion of OA to glycolic acid. 13 and standard glycolic acid demonstrates chemical shifts at δ 59.23 (s, C) and 176.22 (s, C) (Figure 5c). The products from the battery cathode demonstrate chemical shifts at δ 59.16 (s, C) and 176.11 (s, C), suggesting the formation glycolic acid (Figure 5c).…”

An Electrochemical Neutralization Cell for Spontaneous Water Desalination

“…Recently, desalination was reported in metal ion batteries and supercapacitors during electric power generation. [19][20][21][22] Although this integrates an additional dimension to batteries that are otherwise confined to the domain of energy storage, [23][24][25][26][27][28][29][30][31] desalination requires irreversible consumption of the free energy of an active metallic anode. 32,33 A part of the electrical energy stored in the batteries due to the charging redox reactions is utilized for desalination during the discharge.…”
