Influence of additives in a PVDF-based solid polymer electrolyte on conductivity and Li-ion battery performance

Abstract

The transformation of PVDF from α-phase to β-phase makes PVDF more polar and decreases the crystallinity of PVDF.

The Effect of Different Mixed Organic Solvents on the Properties of p(OPal-MMA) Gel Electrolyte Membrane for Lithium Ion Batteries

“…In order to explore the practical application performance of GPEs in LIBs, the galvanostatic charge and discharge tests of Li/GPEs/LiFePO4 cells were investigated and the initial profiles at 0.1 C rate were shown in Figure 6a. A typical charge-discharge potential plateau of LiFePO4 appeared clearly at around 3.4~3.5 V, which was consistent with its typical electrochemical behavior previously reported [39][40][41], indicated a reversible cycling process. Remarkably, the GPE prepared from S2-4 membrane delivered an initial charge capacity of 167 mAh/g ( Figure 7a); it was close to the theoretical specific capacity (170 mAh/g).…”

Optical properties and ionic conductivity studies of an 8 MeV electron beam irradiated poly(vinylidene fluoride-co-hexafluoropropylene)/LiClO4electrolyte film for opto-electronic applications

“…Hence, the electrochemical stability of the polymer electrolytes can be improved with increasing EB dose. 51,52 From Fig. 12, it is clear that the increased peak currents and potential peak separation (redox peak) for the increased EB dose suggests a fast electron transfer at the interface of the irradiated electrolyte 53,54 which is very good for potential applications, especially in Li-ion rechargeable battery applications.…”

Dielectric polarization and relaxation processes of the lithium-ion conducting PEO/PVDF blend matrix-based electrolytes: effect of TiO2 nanofiller

“…Therefore, the blends of PEO with several polymers of better thermophysical properties are largely considered for the preparation of promising SPE, NSPE, PSPE, and PNSPE materials [14, 17-21, 26, 31, 32, 36, 43]. The semicrystalline polar poly(vinylidene fluoride) (PVDF) matrix has relatively appreciable physicochemical and electroactive properties [44] and therefore it is considered in several researches for the development of advanced SPE materials [45][46][47]. Numerous studies on the blend matrices of PEO/PVDF have realized some favourable properties in regards to their suitability as a host matrix for the SPEs and therefore this polymer blend matrix is used for the preparation of a variety of SPEs [13-15, 35, 36, 48] and also electrolyte membranes [16,49,50] suitable for all-solidstate ion-conducting devices.…”
