Electrochemical apparatus, preparation method thereof, and electronic apparatus |
| abstract |
An electrochemical apparatus includes a positive electrode plate including a positive electrode active material layer; a negative electrode plate including a negative electrode active material layer; and a separator disposed between the positive electrode plate and the negative electrode plate. A mass ratio of fluorine to sulfur in a surface layer of the positive electrode active material layer is A, and a mass ratio of fluorine to sulfur in a surface layer of the negative electrode active material layer is B, where 30 ≤ A ≤ 300, and 5 ≤ B ≤ 50. |
