| titleOfInvention | Electrochemical device and electronic device including the same |
| abstract | The present application relates to an electrochemical device and an electronic device including the same. The electrochemical device comprises a positive electrode, a negative electrode, a separator, and an electrolyte, wherein the electrolyte contains a nitrile compound and a transition metal ion, and satisfies: 5≤A/B≤30000, wherein in terms of the molar amount of the electrolyte, the The molar percentage of cyano groups in the electrolyte is A%, and the weight percentage of transition metal ions in the electrolyte is B% based on the weight of the electrolyte. The electrochemical device reduces the dissolution of transition metal ions of the positive electrode active material and stabilizes the structural distortion of the positive electrode active material during charging and discharging by determining that the cyano group in the electrolyte and the transition metal ion satisfy a certain relationship, thereby improving the electrochemical device. High temperature cycle performance and float performance. |
