SECONDARY BATTERY ELECTRODE, AND METHOD FOR PRODUCING SAME

A method for producing a secondary battery electrode, according to the present invention, comprises: a slicing step for producing an active material film by slicing an active material bulk; and a binding step for combining a current collector and the active material film. A method for producing a secondary battery electrode according to the present invention produces an active material film by slicing an active material bulk, which is a free-standing molded body or pellet, thus allowing binder-free active material film to be produced, and as no actual restrictions exist for the thickness of the active material film, thick active material film can be produced, and thus electrodes having high-loading and high composite density can be produced. 本发明的二次电池用电极的制造方法包括：切割步骤，将活性物质块体进行切割以制造活性物质膜；以及粘合步骤，使集流体和所述活性物质膜一体化。本发明的一个实施方案的二次电池用电极的制造方法中，通过切割活性物质块体来制造活性物质膜，所述活性物质块体是可自支撑的成型体或烧结体，因此可以制造无粘着剂的活性物质膜，并且对活性物质膜的厚度没有实质性限制，因此可以制造厚膜形式的活性物质膜，并且具有可以制造高负载和高混合物密度的电极的优点。
