| abstract | Embodiments of the present application provide electrochemical devices and electronic devices. The electrochemical device includes: a positive pole piece, the positive pole piece includes a positive electrode current collector and a diaphragm layer arranged on the positive electrode current collector, and is tested by Fourier transform infrared spectroscopy, and the diaphragm layer contains at least 2800cm -1 to 3200cm -1 . 2 stretching vibration peaks. The present application improves the cycle performance of the electrochemical device by making the membrane layer of the electrochemical device contain at least two stretching vibration peaks at 2800cm -1 to 3200cm -1 . |
