Liquid crystalline lithium-ion electrolytes derived from biodegradable cyclodextrin

Abstract

A cyano-tetraethylene glycol functionalized amphiphilic cyclodextrin forms liquid crystalline self-assembly that shows promising ion conductivity (Li+).

In situpolymerization process: an essential design tool for lithium polymer batteries

“…Ultimately, a variety of PEs such as polymer composite electrolytes (PCEs), hybrid polymer electrolyte (HPEs), singleion conducting polymer electrolytes (SIC-PEs), reinforced polymer electrolyte, cross-linked polymer electrolytes, so forth, and so on are possible to be realized that can be either SPE or GPE depending on the processing steps and components involved (Figure 4). [192][193][194][195] Detailed classification of PEs and further discussion on their properties are available elsewhere. 65,66,172,[196][197][198][199] SPEs/DPEs: In a typical DPE, salt is dissolved solely by the host polymer matrix without any external liquid/liquid-like plasticizers (Figure 4 (1)).…”

Design rules for liquid crystalline electrolytes for enabling dendrite-free lithium metal batteries

“…We find the other ether and ester-based LC molecules (PubChem compound identifiers [CIDs] 170879 and 2058335) have similar stability, while, among the molecules considered, MBBA is the least stable due to the presence of the imine functional group. As shown here, the HOMO levels of these molecules can be manipulated by lowering the acceptor number of the end functional groups ( 91 liquid crystals (44). Engineering the cathode stability will be an important challenge to realize these LC electrolytes in a practical system.…”

“…LC electrolytes typically consist of an LC phase mixed with a conventional organic solvent and Li-containing electrolyte salt. Examples include a rod-like molecule having a mesogenic unit and an alkyl chain terminating in a carbonate moiety and Li bis(trifluoromethylsulfonyl)imide (LiTFSI) used by Sakuda et al (43) and amphiphilic β-cyclodextrins with LiTFSI proposed by Champagne et al (44).…”

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

“…It is expected that advancements in the understanding of magnesium chemistry will lead to the achievement of advanced SEI layers, similar to those formed in traditional LIBs [ 147 , 148 , 149 , 150 , 151 ]. To date, it is of crucial importance that the anode remains free from any solid passivation layer in order to allow reversible stripping/plating.…”

“…Consequently, hypothesize that both thermodynamic stability and diffusion rates of Mg i crystals growth of magnesium depositions [71,146]. It is expected that advancements in the understanding of magnesium lead to the achievement of advanced SEI layers, similar to those formed in t [147][148][149][150][151]. To date, it is of crucial importance that the anode remains free (e) 1.0 mA cm −2 and (f) 2.0 mA cm −2 .…”
