Original Abstract Submitted

An electrochemical apparatus includes an electrolyte, a positive electrode plate, a negative electrode plate, and a separator, where the separator is disposed between the positive electrode plate and the negative electrode plate; a width W of the electrochemical apparatus and a thickness T of the electrochemical apparatus satisfy: 80 mm≤W≤120 mm, and 2.3≤W/T≤4; and an adhesion force F between the separator and the positive electrode plate is 5 N/m to 15 N/m. With the adhesion force of the separator being regulated within the foregoing ranges, the separator has high adhesive performance. The application of the separator to a wide and thin electrochemical apparatus with a width and W/T value within the foregoing ranges can mitigate the deformation problem of the wide and thin electrochemical apparatus during cycling while taking the rate performance of the wide and thin electrochemical apparatus into account.
