摘要： The present invention provides an electrolyte containing novel additive for electrochemical device and the electrochemical device thereof. The additive is a compound represented by below formula (I): wherein R is defined as herein; n is 2, 3, or 4. The additive of the present invention can protect the surface of the carbonaceous material on the anode, suppresses the occurrence of exfoliation, and therefore increases the lifetime of the electrochemical device. Furthermore, the additive of the present invention also slows down the decay of capacity on the cathode during charging-discharging cycles, and hence maintains a better performance.
