resulting in a low ionic conductivity. To enhance the ionic conductivity of the membrane, many polymer electrolyte membranes (copolymers, block copolymers and random copolymers) are widely studied as a promising membrane applied in LIB because they act not only as an ionic conductor but also as a membrane [8; 9; 10; 11; 12]. Among these polymer electrolyte membrane, poly(methyl methacrylate) (PMMA), a kind of gel polymer electrolyte (GPE) matrix, has been considered as a promising membrane candidate, owing to its high electrolyte uptake and good compatibility with electrode materials [13]. Although PMMA as the matrix of GPE has been studied extensively, there are still some problems including low ionic conductivity and poor mechanical integrity etc., which greatly limit its development in LIB. Various nano particles such as SiO\({}_{2}\), TiO\({}_{2}\) and clay have been used for modifier in the PMMA matrix membrane in order to enhance the properties of PMMA [13; 14; 15]. Palgyorskite (Pal) is a kind of fibrous magnesium aluminosilicate clay. Pal has many distinctive advantages as a modifier, including appropriate interlayer charge, large specific surface area, high aspect ratio and high cation-exchange capacity. [PERSON] et al. [16] found that the Pal can enhance prominently thermal stability and mechanical property of PMMA after Pal was modified by 2,4-tolylene diisocyanate. In the previous study [17], a inorganic-organic hybrid polymer (poly(organic Pal-co-methyl methacrylate), p(OPal-MMA)) was prepared from MMA and organic Pal. The polymer has many net shaped microporous structures and the ionic conductivity of the hybrid polymer-based GPE was \(2.94\times 10^{-3}\) S/cm. However, during experiments, we found that the preparation technologies of the gel polymer membrane using different organic solvents also affect electrochemical characters. Thus, in this study, the preparation technology of GPE is reported especially by phase inversion method using different mixing solvents. On the other hand, many studies have been focused on preparation of the PMMA membrane using different membrane forming methods, such as Bellcore technique [18], solvent casting [19; 20], electrospun [7; 21] and phase inversion [22; 23]. The Bellcore technique has always been utilized in preparing porous polymer membranes with high ionic conductivity at room temperature [18]. However, the extraction process consumes a great deal of organic solvent, largely raising production costs.
