SEPARATOR, ELECTROCHEMICAL DEVICE, AND ELECTRONIC DEVICE

A separator includes a substrate and a ceramic coating layer disposed on at least one surface of the substrate. The ceramic coating layer includes a first filler, a second filler, and a binder. A mass ratio between the first filler, the second filler, and the binder is (88.5 to 99):(0.5 to 10):(0.5...

Zusammenfassung:A separator includes a substrate and a ceramic coating layer disposed on at least one surface of the substrate. The ceramic coating layer includes a first filler, a second filler, and a binder. A mass ratio between the first filler, the second filler, and the binder is (88.5 to 99):(0.5 to 10):(0.5 to 1.5). An ionic impedance of the ceramic coating layer is 0.001 Ω to 0.15 Ω. The separator based on the above settings exhibits a relatively low ionic impedance, indicating that the kinetic performance of the separator is improved. The separator as applied in an electrochemical device improves the kinetic performance of the electrochemical device.
