Abstract
The present application relates to an electrochemical device. The electrochemical device includes: at least one electrode, the at least one electrode having a first surface; and a fiber coating layer, the fiber coating layer including a fiber and being disposed on the first surface. The electrochemical device has the advantages of high energy density, strong liquid retention ability, good drop resistance, good chemical stability and the like since its fiber coating layer has small thickness, high porosity and stronger interfacial adhesion to the electrode.
