Plastic crystal polymer electrolytes containing boron based anion acceptors for room temperature all-solid-state sodium-ion batteries

Block copolymer electrolyte with adjustable functional units for solid polymer lithium metal battery

“…As seen in Fig. S3, different from the high crystallinity of PEO [52], there is only a broad peak of PH-BCPE, indicating the amorphous structure, which is beneficial for the Li + migration [53]. Furthermore, the interfacial compatibility between PH-BCPE and electrodes could also be enhanced by the amorphous structure, which is important for the practical applications of LMBs.…”

A Review of Modification Methods of Solid Electrolytes for All‐Solid‐State Sodium‐Ion Batteries

“…For example, to improve the overall performance, plastic crystal polymer electrolyte (PCPE) supported by nonwovens containing anion‐trapping boron moieties (B‐PCPE) is used for ASSIBs, which was prepared by in situ growth of PCE and boron‐containing cross‐linker inside nonwoven support via UV‐curing technique. [ 74 ] The B‐PCPE simultaneously revealed an excellent RT ionic conductivity of 3.6 × 10 −4 S cm −1 , a high sodium‐ion transference number (≈0.62), and superior tensile strength (28.2 MPa). Evidently, PCPE‐impregnated composite NaNi 1/3 Fe 1/3 Mn 1/3 O 2 (c‐NFM) cathode and hard carbon (c‐HC) anode was designed by in situ growth technique.…”

Development on Solid Polymer Electrolytes for Electrochemical Devices

“…This electrolyte having B -(boron anion) acceptor was prepared via a UV-assisted curing method, using 2-hydroxy-2-methyl-1-phenyl-1-propanone as photoinitiator. This electrolyte demonstrated superior properties in terms of ambient conductivity (3.60 × 10 −4 S cm −1 ), tensile strength (28.2 MPa) and Na + transference number of (t Na+ = 0.62) [196]. Promising results were also obtained after applying the electrolyte in Na-ion batteries (initial capacity of ~105 mAh g −1 at 0.1 C and retaining 80% capacity after 120 cycles) [196].…”

“…Plastic crystal SN has also been employed as a polymer matrix in electrolyte, besides serving as a plasticizer and ionizer for both Li-and Na-based salts [131,196]. In order to improve the transference number of Na + , Chen et al [196] synthesized boroncontaining 2-hydroxyethyl methacrylate (B-HEMA) before incorporating it into SN-based polymer electrolyte that had non-woven polypropylene-cellulose composite framework and NaClO 4 salt. This electrolyte having B -(boron anion) acceptor was prepared via a UV-assisted curing method, using 2-hydroxy-2-methyl-1-phenyl-1-propanone as photoinitiator.…”
