abstract |
The present invention relates to a composition for forming a separator, a separator formed from the composition, and a battery using the same, and more particularly, to a separator having a heat resistance and strength suitable for the separator and a reduced air permeability. More particularly, the present invention provides a composition for forming a separation membrane including a plasticizer having a low viscosity and a method for manufacturing a separation membrane using the same, thereby manufacturing a separation membrane capable of improving not only air permeability but also porosity and battery stability. |
