ELECTROCHEMICAL APPARATUS AND ELECTRONIC APPARATUS

An electrochemical apparatus includes a first electrode plate, a second electrode plate, a first separator, and a second separator, the first separator includes a first porous substrate, the second electrode plate includes a second porous substrate, and the first electrode plate, the first separator, the second electrode plate and the second separator are stacked in sequence to form an electrode assembly; and at least one surface of the first porous substrate is provided with a polymer bonding layer, and at least one surface of the second porous substrate is provided with no polymer bonding layer. The electrode assembly structure separate a positive electrode plate and a negative electrode plate through a first separator provided with a polymer binder, which is beneficial to shape the electrode assembly and release a stress at corner, thereby inhibiting deformation of the electrochemical apparatus.
