Abstract: An electrochemical device including an anode having an anode current collector and a skeleton layer, the skeleton layer being disposed in an central region on the anode current collector, and a region, not covered by the skeleton layer, on the anode current collector being provided with an insulation layer; a cathode; and an electrolyte including about 1 wt % to about 40 wt % of a sulfone compound, about 1 wt % to about 40 wt % of a phosphorus compound and about 1 wt % to about 70 wt % of a fluoroether compound, based on the total weight of the electrolyte. The electrochemical device has superior cycle performance and safety performance.
