| titleOfInvention | An electrochemical device and electronic device |
| abstract | The application provides an electrochemical device and an electronic device, the electrochemical device includes a positive electrode piece and an electrolyte, wherein the positive electrode piece includes a positive electrode tab, and the working length b of the positive electrode tab is 0.5m to 3m; the electrolyte includes Cyclic carbonate, based on the quality of the electrolyte, the mass percentage of the cyclic carbonate is a%, and the cyclic carbonate includes ethylene carbonate and/or propylene carbonate; the electrochemical device satisfies 13≤a/b ≤110. By adjusting the working length b and a/b of the positive electrode tab within the above ranges, and selecting the above cyclic carbonate, it is beneficial to form a synergistic effect between the positive electrode tab and the electrolyte, so as to improve the cycle performance of the electrochemical device , high temperature performance and safety performance, etc., will not affect the kinetic performance of the electrochemical device, thereby improving the overall performance of the electrochemical device. |
