Title:
ELECTROCHEMICAL DEVICE AND ELECTRONIC DEVICE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2021/179300
Kind Code:
A1
Abstract:
An electrochemical device, comprising a positive electrode, a negative electrode, and an electrolyte, wherein the electrolyte comprises an anion of a phosphorus pentoxide functional group of the specific structure. By adding the anion to the electrolyte, both the low-temperature discharge performance and the high-temperature storage performance of the electrochemical device can be improved and considered, and the cycle stability of the electrochemical device at room temperature and high temperature can be improved.
