Beschreibung
Zusammenfassung:	A separator and an energy-storing electrochemical device are disclosed, the separator includes a porous substrate and a first coating located on at least one surface of the porous substrate. The first coating includes a first polymer binder and first inorganic particles, and the first polymer binder comprising core-shell structured particles. The first inorganic particles are used in the first coating, ensuring that the first polymer binder has a bonding function, electrolyte transport is promoted, and the rate performance of the electrochemical device is improved.
