    Abstract: An electrode plate and a method for preparing same are provided. The electrode plate according to this application includes a current collector and an electrode material layer disposed on at least one surface of the current collector. The electrode material layer includes an active material and optionally a conductive agent. The electrode material layer includes a compound represented by Formula (I). The electrode plate according to this application is characterized by a relatively high porosity, more uniform distribution of pores, a more noticeable effect of being initially infiltrated by an electrolytic solution, a higher capacity of retaining the electrolytic solution, alleviated initial polarization, and a reduced direct-current resistance (DCR), and therefore, can improve the performance of a battery that contains the electrode plate.
