Separator For Electrochemical Devices And Method For Manufacturing Same Separator
Abstract: The present invention relates to a method for manufacturing a separator for an electrochemical device comprising a silicon-based negative electrode, the method comprising a step of forming a free-standing porous separator by simultaneously electrospinning a first spinning solution comprising a polymer binder and a second spinning solution comprising inorganic particles, in which, by making the flow rate of the second spinning solution greater than the flow rate of the first spinning solution, a separator with compression resistance against expansion of the silicon-based negative electrode during charging and discharging can be manufactured.
