An ionic liquid crystal-based solid polymer electrolyte with desirable ion-conducting channels for superior performance ambient-temperature lithium batteries

Abstract

Almost all the traditional ionic liquids lack liquid crystal properties.

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)).…”

Li7La3Zr2O12 Garnet Solid Polymer Electrolyte for Highly Stable All-Solid-State Batteries

“…Moreover, the PEO offers several additional advantages, such as excellent electrochemical stability, ease of fabrication, low cost and improved safety (Jiang et al, 2018 ). However, ionic conductivities of typical linear PEO-based SPEs at room temperature are normally low (≤10 −6 S cm −1 ) owing to the high crystallinity of the EO (Wang et al, 2018 ). To enhance ionic conductivities, strategies including the use of block copolymer electrolytes (Pelz et al, 2018 ), cross-linked polymer electrolytes (Sakakibara et al, 2019 ), interpenetrating network polymer electrolytes (Tong et al, 2018 ), and composite polymer electrolytes (Liu et al, 2017 ; Yao et al, 2019 ) have been proposed.…”

Gel-polymer electrolytes based on polyurethane ionomers for lithium power sources

“…[28][29][30] To increase the ionic conductivity, it was proposed to plasticize SPE with organic solutions of a lithium salt and ionic liquids. [31][32][33][34][35][36][37][38][39] Retention of lithium ions solutions by a polymer matrix leads to the formation of polymer gel electrolytes (GPE), 40 which simplify the technology of manufacturing various electrochemical devices with effective electrode-electrolyte contacts. [24][25][26][27][28] At this moment, polymer matrices based on polyethylene oxide (PEO), [41][42][43][44][45] polycarbonate (PC), 46,47 polyacrylonitrile (PAN), 48 poly(methyl methacrylate) (PMMA) 49,50 and polyvinylidene uoride (PVDF) 51 are well studied.…”
