Case Study

Poly (vinyl chloride-co-vinyl acetate) for lithium-ion batteries

Sung, Hsi-yueh, Yung-yun Wang, and Chi-chao Wan. Journal of the Electrochemical Society 145.4 (1998): 1207.

Two methods can effectively alleviate the solvent leaching problem of pure poly(yinylchloride)(PVC) electrolytes, namely, replacing pure PVC homopolymer with poly(vinylchloride-co-vinyl acetate)(PVCA) copolymers and directly using good solvents of PVC or PVCA instead of using auxiliary carrier solvents. Based on solubility parameters, dielectric constants and other related parameters, N,N-dimethylformamide(DMF) and N-methyl pyrrolidionone(NMP) and ethylenecarbonate(EC) and/or propylenecarbonate(PC) were selected as cosolvents. The ambient temperature conductivity and electrochemical stability window of PVCA-NMP/EC-LiC1O4 were 1.2>(10'Scm' and 4.9V vs.Li/i0Scm' and 4.6V vs.Li/Lit, respectively. The corresponding performances of PVCADMF/EC/PC-LiC1O4 were measured to be 4.6V vs.Li/Lit, respectively. These noteworthy performances provide inspiration for the practical application of secondary lithium batteries.
PVC or PVCA was vacuum dried at 80 °C for 24 h. THF, DMF, and NMP were dried over molecular sieves for several days before use. Ethylene carbonate, propylene carbonate, and lithium perchlorate were used as received. First, lithium salts were dissolved in the EC/PC/DM For EC/PC/NMP mixture in a vial using a magnetic stirring bar. Second, PVCA powder was gradually added to the mixture under continuous stirring. Meanwhile, the mixed slurry was slowly heated to -100 °C. to promote the swelling of the polymer. The transparent, highly viscous melt is cast onto a glass plate. Finally, a polymer electrolyte with a translucent, elastic appearance is obtained after 1 or 2 days at room temperature. The entire preparation process is carried out in an environmentally controlled drying room. Sample Characterization - The electrolyte conductivity is measured by the impedance method by sandwiching a given sample between two stainless steel (SS304) barrier electrodes. The precise electrolyte thickness is determined by a rigid spacer of known thickness (<100p.m) around the sample. The measurements are performed using an analyzer. The applied frequency range is from 0.1 to 50kHz.

Novel polydimethylsiloxane (PDMS) and poly(vinylchloride-co-vinyl acetate) (PVCA) blend membranes for CO2 separation

Maiti, Jatindranath, et al. International Journal of Hydrogen Energy 41.13 (2016): 5776-5782.

Novel membranes of pure polydimethylsiloxane (PDMS) and poly(vinylchloride-co-vinyl acetate) (PVCA) and their blends in five ratios were synthesized and further characterized. Thermal and mechanical stability can be improved by increasing the concentration of PVCA. The seven prepared membranes were evaluated in permeation settings at two different temperatures (25°C and 75°C), and the results showed that the permeance of PDMS membranes at 75°C was higher than that at 25°C in the case of N2 and CH4, which may indicate that the pore size changes at higher temperatures, facilitating the diffusion of gases. The results indicate that the addition of PVCA in PDMS enhances the permeability and desirable selectivity of the membranes. Among them, PP-4 with a mixing ratio of 96:4 showed a maximum ideal selectivity of 21.1 for CO2 at 25°C and 10 psi and a maximum permeability of 5595 barr. But its thermal stability was slightly compromised. In contrast, PP-5 was more thermally stable than the other membranes. The results of this study showed that PDMS and PVCA are compatible and therefore conducive to the formation of a uniform and dense film structure.
First, a pure PDMS A solution was prepared by adding 4g of PDMS to 20 ml of ethyl acetate and stirring continuously for one hour. Then 4g of PDMS B was added with continuous stirring at 50°C for 2 hours. After that, PVCA was added to the PDMS solution. The first solution variant was 99% PDMS and 1% PVCA (dissolved in ethyl acetate) with continuous stirring at 60°C for 6 hours. All subsequent variants were prepared in the same manner, but with 1% increase in PVCA content, i.e., 98:2, 97:3, 96:4, 95:5. These casting solutions were left at room temperature for 24 h to remove the microbubbles formed therein and then cooled at room temperature.
