<![CDATA[ Rechargeable batteries consist of electrode, separator, and electrolyte. Separator used as medium transfer ions and to prevent electrical short circuits in battery cells. Commonly used a solid separator (polyethylene, celgard) and a liquid electrolytes. Recently poly(vinylidene fluoride) (PVdF) were developed into a based gel polymer electrolytes and as separator at once. The advantage of PVdF has a high porosity and more stable against hard chemical also high temperature. The aim of this research to investigate the effect of non-solvent to characteristic membranes. In order to produce better outcome add 7% polyvinylpyrrolidone (PVP) as a pore forming agent and 10% nonoclay as filler. Phase-inversion is a common methode to form a microporous membranes. This methode was prepared by dissolving Nanoclay and PVP in solvent for 2 hours, and then add the PVdF/PVdF-HFP with stirring at 60°C. After 4 hours, casting in a glass and immersed in non-solvent. N,N-Dimethylformamide (DMF) is used as solvent, while for non-solvent are variated: aquadest, N-Methyl Pyrollidone (NMP) 10%, Natrium Clorida (NaCl) 10%. The membranes were characterized by porosity test, electrolytes uptake test, and Fourier Transform Infrared (FTIR). The best result using aquadest as non-solvent provide 60% electrolyte uptake, and with non-solvent NaCl give porosity 80%]]>
