Sandwich-structural ionogel electrolyte with core–shell ionic-conducting nanocomposites for stable Li metal battery

Study of Capacitive Behavior and its Inter-Relationship with Electrolyte Solution Concentration in Hybrid Ionogels

“…At higher concentration of electrolyte solution (40 vol%), the ionogel achieved a much lower thermal stability (343 °C), which could be due to the high electrolyte content. Thus, the optimum thermal stability is achieved by IG-30, which is 358 °C, that is higher than 300 °C reported by He et al 24 Such high thermal stability has confirmed the applicability of ionogel in high temperature environment 25 and lithium ion batteries. 26 The DTG curve also confirmed that the ionogel exhibits high decomposition temperature, demonstrating that the ionogel has an excellent thermal stability.…”

Efficient Bifunctional NiFe-LDH@Co9S8 Nanoflower Electrocatalysts Anchored with Pt Nanocrystal for Flexible Quasi-solid Rechargeable Zinc Air Battery

“…40,41 Organic ionic liquid (IL), as additive, was widely used in the hydrogel to form an organohydrogel to prevent water evaporation. 42,43 Therefore, we designed a hydrogel composed of sodium polyacrylate (PANa), carboxymethyl cellulose (CMC) as polymer skeleton, and 1-ethyl-3methylimidazolium chloride (EMImCl), acetamide as IL, which absorbed the water from air to alleviate water loss. The PANa-CMC-IL hydrogel exhibited a higher ionic conductivity (136.4 mS cm −1 ) than that of that of PANa (87.8 mS cm −1 ) and PANa-CMC hydrogel (94.4 mS cm −1 ) based on the Nyquist plot of the three types of hydrogel (Figure 6b).…”

“…The most remarkable thing was that the hydrogel could maintain the electrolytes when FZABs were folded. In general, the optimized hydrogel electrolytes for hydrogels should meet the following three conditions: (1) high ionic conductivity; (2) high water uptake and strong water retention; and (3) stability with alkane. , Organic ionic liquid (IL), as additive, was widely used in the hydrogel to form an organohydrogel to prevent water evaporation. , Therefore, we designed a hydrogel composed of sodium polyacrylate (PANa), carboxymethyl cellulose (CMC) as polymer skeleton, and 1-ethyl-3-methylimidazolium chloride (EMImCl), acetamide as IL, which absorbed the water from air to alleviate water loss. The PANa-CMC-IL hydrogel exhibited a higher ionic conductivity (136.4 mS cm –1 ) than that of that of PANa (87.8 mS cm –1 ) and PANa-CMC hydrogel (94.4 mS cm –1 ) based on the Nyquist plot of the three types of hydrogel (Figure b).…”

Recent advances in designing solid-state electrolytes to reduce the working temperature of lithium batteries

“…Many researchers use the strategy of multi-layer structure to design electrolytes to meet the needs of different electrodes. 154 For example, the excellent flexibility of PEO can make it fully contact with the cathode, and its decomposition products on the lithium cathode can passivate this electrode. 155,156 On the other hand, polyacrylonitrile (PAN) has good resistance to high pressure and high temperature, and its butyronitrile group has a strong interaction with Li + , which makes the lithium salt more soluble and improves ionic conductivity.…”
