Compatibility and thermal stability studies on plasticized PVC/PMMA blend polymer electrolytes complexed with different lithium salts

Abstract

The lithium salt (x) (X= LiAsF6, LiPF6, LiN(C2F5SO2)2 , LiN(CF3SO2)2, LiBF4) was complexed with a host of poly(vinyl chloride) (PVC)/ poly(methyl methacrylate) (PMMA) blend polymer and plasticized with a combination of ethylene carbonate (EC) and propylene carbonate(PC). The polymer electrolyte films were prepared for constant PVC/PMMA blend ratio. The electrochemical stability and thermal stability of the solid polymer electrolytes were reported. The role of PMMA to the phenomena occurring at the interface between the electrolyte and the lithium metal electrode was explored

PREPARATION AND FTIR STUDIES OF PMMA/PVC POLYMER BLENDS, PVC-g-PMMA GRAFT COPOLYMERS AND EVALUATING GRAFT CONTENT

“…It has been found that plasticized PMMA could be used as gel electrolytes for lithium batteries [3,4]. The possibility  Presented at the Conference: "3 rd International Workshop CPM2018" of using plasticized PMMA-based polymer blends as gel electrolytes have been also explored [5][6][7][8][9]. Among them, poly(vinyl chloride) (PVC) is more often used for improving the poor mechanical properties of PMMA gel when using with high level of plasticizers.…”

“…The plasticized PMMA/PVC blends have been receipted much attention because they are promised materials for polymeric electrolyte application. Some studies have showed that the miscibility of PMMA/PVC blends depends on molecular weights and proportion of each component [8][9][10][11][12][13][14], Therefore, using of a compatibilizer can further improve properties of the PMMA/PVC blends. Recently, Li et al [11] have synthesized poly(methyl methacrylategraft -polyvinylchloride) (PMMA-g-PVC) for blending with PMMA in order to prepare dual-phase polymer electrolytes, in which PMMA grafted content was evaluated by proton nuclear resonance spectroscopy with the value of 6.1 weight percent (wt.%).…”

Preparation and properties of biodegradable polymer-layered silicate nanocomposite electrolytes for zinc based batteries

“…For practical applications, a polymer electrolyte ought to be thermally stable in order to guarantee the performance of the device and its safe operation even at elevated temperatures [26]. It is important that the polymer electrolyte should be stable atleast upto 150 C. The observed TGA profiles of pure PCL, optimized polymer-salt complex (Pz25) and the best conducting PLSNE sample M15 are shown in Fig.…”
