“…Ren et al proposed a mechanism of competitive coordination of [Tf 2 N] – to dramatically increase the current density of Mg plating/stripping. In addition to the use of conventional ionic liquids, a zwitterionic liquid, 1-butyl-3-methylimidazol-2-ylidene borane, was initially investigated by Tröger-Müller and Liedel as the electrolyte system, performing higher reversibility and stability than the isostructural [BMIM][Tf 2 N] ([BMIM] + = 1-butyl-3-methyl-imidazolium). Furthermore, Gao and co-workers , extended their concept from a previous study, achieving reversible Mg plating/stripping with alkoxy functionalized ILs, and demonstrated a remarkable Ca/V 2 O 5 cell using (Ca[BH 4 ] 2 ) 0.05 ([N 07 ][Tf 2 N]) 0.95 , where the alkoxy-functionalized ammonium cation ([N 07 ] + = N , N , N -tri-(2-(2-methoxyethoxy)ethyl)- N -(2-methoxyethyl)ammonium) was revealed that effectively optimizes the calcium coordination sphere for the high reversibility.…”

Ionic liquids (ILs) consisting entirely of ions exhibit many fascinating and tunable properties, making them promising functional materials for a large number of energy-related applications. For example, ILs have been employed as electrolytes for electrochemical energy storage and conversion, as heat transfer fluids and phase-change materials for thermal energy transfer and storage, as solvents and/or catalysts for CO2 capture, CO2 conversion, biomass treatment and biofuel extraction, and as high-energy propellants for aerospace applications. This paper provides an extensive overview on the various energy applications of ILs and offers some thinking and viewpoints on the current challenges and emerging opportunities in each area. The basic fundamentals (structures and properties) of ILs are first introduced. Then, motivations and successful applications of ILs in the energy field are concisely outlined. Later, a detailed review of recent representative works in each area is provided. For each application, the role of ILs and their associated benefits are elaborated. Research trends and insights into the selection of ILs to achieve improved performance are analyzed as well. Challenges and future opportunities are pointed out before the paper is concluded.

“…To circumvent this issue, a protecting group may be introduced after synthesis, for example upon formation of an N‐heterocyclic carbene (NHC) borane in an easy way . The resulting zwitterions indeed show superior reductive stability and have recently been described as the solvent component in the electrolyte of magnesium batteries . Applying this approach of forming an NHC borane to truly sustainable imidazolium ionic liquids may consequently also lead to the use of sustainable imidazolium‐type ionic liquids in electrolytes for magnesium‐ion batteries.…”

Sustainable sources of energy have been identified as a possible way out of today's oil dependency and are being rapidly developed. In contrast, storage of energy to a large extent still relies on heavy metals in batteries. Especially when built from biomass‐derived organics, organic batteries are promising alternatives and pave the way towards truly sustainable energy storage. First described in 2008, research on biomass‐derived electrodes has been taken up by a multitude of researchers worldwide. Nowadays, in principle, electrodes in batteries could be composed of all kinds of carbonized and noncarbonized biomass: On one hand, all kinds of (waste) biomass may be carbonized and used in anodes of lithium‐ or sodium‐ion batteries, cathodes in metal–sulfur or metal–oxygen batteries, or as conductive additives. On the other hand, a plethora of biomolecules, such as quinones, flavins, or carboxylates, contain redox‐active groups that can be used as redox‐active components in electrodes with very little chemical modification. Biomass‐based binders can replace toxic halogenated commercial binders to enable a truly sustainable future of energy storage devices. Besides the electrodes, electrolytes and separators may also be synthesized from biomass. In this Review, recent research progress in this rapidly emerging field is summarized with a focus on potentially fully biowaste‐derived batteries.

“…However, they still face many challenges, such as high prices, a scarcity of resources, and safety issues. It is predicted that LIBs might not be able to meet the needs of road transport electrification in the near future . Rechargeable magnesium batteries (RMBs), as a sustainable energy storage system, have recently attracted attention as a beyond lithium battery owing to the low price of magnesium, potential stability in air, high theoretical volumetric capacity (∼3833 vs 2062 mAh cm –3 for Li) and the low reduction potential (−2.4 V vs SHE). , Despite these positive features, there are two major challenges that need to be overcome before realizing practical RMBs.…”

With a low cost and high volumetric capacity, rechargeable magnesium batteries (RMBs) have emerged as promising candidates for post-lithium ion batteries. The kinetically sluggish Mg 2+ insertion/ extraction in the host lattice and the anode/electrolyte incompatibility render the battery irreversible in some instances and restrict the commercial applications. In this work, we replace the conventional electrolyte with a dual layer of liquid and polymer electrolyte onto the cathode and anode, respectively, and investigate the structural, electrical, and electrochemical properties. It exhibits a remarkable Mg-ion conductivity up to 4.62 × 10 −4 S cm −1 at 55 °C, a high transfer number (t Mg 2+ = 0.74), low overpotential, and relatively stable Mg stripping and plating during the initial cycles. Furthermore, this work uses an unconventional electrode, BaTiO 3 (BTO), to demonstrate the performance of Mg batteries and track the structural and electrochemical changes. The quasi-solid-state Mg batteries fabricated with premagnesiation and thermally treated BTO cathode materials show good electrochemical performance. The approaches herein may provide new directions for exploiting high-performance Mg batteries through the perovskite structure cathode and functional dual electrolyte.
