摘要：
A non-aqueous electrolyte secondary battery of the present invention includes a positive electrode including a layer of active material particles, a negative electrode including a layer of active material particles and a non-aqueous electrolyte. An organic film including a conductive agent and having a low affinity to the non-aqueous electrolyte is formed on a portion of at least one electrode selected from the positive electrode and the negative electrode. Accordingly, there are provided a non-aqueous electrolyte secondary battery that exhibits a small decrease in capacity during repeated charge/discharge, a method for producing the same and an electrode material for an electrolyte battery.
