Secondary battery electrode, and method for producing same
摘要
說明書
In the method or producing an electrode for a secondary battery according to an exemplary embodiment of the present invention, the active material film maintains an open pore network that is uniform (designed) substantially independently of thickness, thereby achieving uniform and stable impregnation of an electrolyte solution.
Since the active material film being an independent member may be a binder-free film containing no organic binder, the secondary battery according to an exemplary embodiment of the present invention allows high loading and a high mixture density formation, and thus, the electrode may easily implement high energy density battery design.
Though the secondary battery according an exemplary embodiment of the present invention is in the form of a thick film due to the orientation of the active material film being an independent member or a structure bound by an interparticle neck, an electrolyte solution (and lithium ions) may be impregnated therein uniformly and stably.
