Ionic liquids (ILs) have emerged as a novel class of chemical compounds for the development of advanced (multi)functional materials with outstanding potential in applications of several areas due to their unique properties and functionalities. The combination of ILs with polymers, in a composite, allows for developing smart materials, which synergistically combine the features of specific polymers and ILs. Moreover, ILs can be extensively modified by the incorporation of functional groups with specific properties into the cation, anion, or both. Thus, it is possible to tune the IL, the polymer, or both to obtain a broad spectrum of multifunctional composites and address the specific requirements of many applications. This work focusses on advanced materials and strategies concerning ILs and polymers for the development of smart IL/polymer‐based materials for applications including responsive and sensitive sensors, actuators, environment, batteries, fuel cells, and biomedical applications.

“…In particular, IL have been used for the development of SPE based on 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide, [EMIM][TFSI], 1-butyl-3-methylim-idazolium bis(trifuoromethanesulfonyl)imide, [BMIM][TFSI], 1-ethyl-3-methylimidazo-lium tetrafluoroborate, [EMIM][BF 4 ], 3-methy-1-propylimi-dazolium bis(trifluoromethysulfony) imide, [PMIM][TFSI], N- n -butyl- N -methylpyrrolidinium bis(trifluoromethanesulfonyl)imide, [Pyr14][TFSI], among others. These ILs have been used to increases the ionic conductivity of SPEs, based on its high conductivity, being, as an example, to 10 –3 S cm –1 at 80 °C values for N- n -butyl- N -methylpyrrolidinium bis(trifluoromethanesulfonyl)imide, [Pyr14][TFSI] .…”

Materials sustainability is becoming increasingly relevant in every developed technology and, consequently, environmentally friendly solid polymer electrolytes (SPEs) based on gellan gum and different quantities of ionic liquid (IL) 1-ethyl-3-methyl-imidazolium-thiocyanate [Emim][SCN] have been prepared and applied in electrochromic devices (ECDs). The addition of the IL does not affect the crystalline phase of gellan gum, and the samples show a compact morphology, surface uniformity, no phase separation, and good distribution of the IL within the carrageenan matrix. The developed SPE are thermally stable up to ∼100 °C and show suitable mechanical properties. The most concentrated sample (39 wt % IL content) reaches a maximum ionic conductivity value of 6.0 × 10–3 S cm–1 and 1.8 × 10–2 S cm–1 at 30 and 90 °C, respectively. The electrochromic device (ECD) was fabricated with poly(3,4-ethylenedioxythiophene) polystyrenesulfonate (PEDOT:PSS) as working electrode and the developed SPE was compared with an aqueous 0.1 M KNO3 solution. The electrochromic performance of the electrolyte was assessed in terms of spectroelectrochemistry, demonstrating a fully flexible ECD operating at voltages below 1.0 V. This novel electrolyte opens the door to the preparation of high performance sustainable ECD.

“…It is, therefore, clear that, in order to reach a correct integration of renewables, a way to store energy when in excess and to use it when needed is necessary [ 35 , 36 , 37 , 38 , 39 ]. Still referring to the “duck curve”, a significant step forward in terms of efficiency and reduction of CO 2 emissions would be made if the excess of photovoltaic electricity produced in the middle of the day was stored and used after the sunset, concurring to satisfy the high demand of the evening and avoiding the over-generation risks [ 40 , 41 , 42 , 43 , 44 ]. This is what is highlighted in the graph shown in Figure 1 B.…”

An Overview on Anodes for Magnesium Batteries: Challenges towards a Promising Storage Solution for Renewables

et al. 2021

View full text Add to dashboard Cite

Magnesium-based batteries represent one of the successfully emerging electrochemical energy storage chemistries, mainly due to the high theoretical volumetric capacity of metallic magnesium (i.e., 3833 mAh cm−3 vs. 2046 mAh cm−3 for lithium), its low reduction potential (−2.37 V vs. SHE), abundance in the Earth’s crust (104 times higher than that of lithium) and dendrite-free behaviour when used as an anode during cycling. However, Mg deposition and dissolution processes in polar organic electrolytes lead to the formation of a passivation film bearing an insulating effect towards Mg2+ ions. Several strategies to overcome this drawback have been recently proposed, keeping as a main goal that of reducing the formation of such passivation layers and improving the magnesium-related kinetics. This manuscript offers a literature analysis on this topic, starting with a rapid overview on magnesium batteries as a feasible strategy for storing electricity coming from renewables, and then addressing the most relevant outcomes in the field of anodic materials (i.e., metallic magnesium, bismuth-, titanium- and tin-based electrodes, biphasic alloys, nanostructured metal oxides, boron clusters, graphene-based electrodes, etc.).
