SEPARATOR FOR ELECTROCHEMICAL DEVICES AND METHOD FOR MANUFACTURING SAME SEPARATOR
20250149735 · 2025-05-08 ·

A method for manufacturing a separator for an electrochemical device including a silicon-based negative electrode is provided. The method includes a step of forming a freestanding porous separator by simultaneously electrospinning a first spinning solution containing a polymer binder and a second spinning solution containing inorganic particles, wherein a flow rate of the second spinning solution is allowed to be greater than that of the first spinning solution such that a separator having compression resistance against expansion of the silicon-based negative electrode during charging and discharging is manufactured.
