Separation membrane manufacturing method, separation membrane and battery using the same |
| abstract |
The present invention relates to a method for producing a polyolefin-based porous separation membrane, and the tensile strength and the heat shrinkage ratio are improved by adjusting the stretching ratio of the base film during the casting treatment and the stretching treatment during the production process of the separation membrane. The present invention relates to a method for manufacturing a separation membrane. The present invention also relates to a polyolefin-based porous separation membrane having excellent tensile strength and improved thermal shrinkage and puncture strength since the difference in tensile strength between the longitudinal direction and the transverse direction of the separation membrane is small. The present invention also relates to an electrochemical cell that uses the separation membrane to improve shape stability due to heat and tension. |
