摘要:
To provide a structure which allows production of an electrode, even if the film thickness of an electrode is increased; and a non-aqueous electrolyte secondary battery using the same.
A non-aqueous electrolyte secondary battery including a power generating element including: two electrodes having different polarity and formed by forming an active material layer on a current collector; and an electrolyte layer positioned between the electrodes, wherein at least one of the active material layers of the two electrodes having different polarity contains an active material and a conductive member made from an electron conducting material, the active material layer has a first principal surface which comes into contact with the electrolyte layer side, and a second principal surface which comes into contact with the current collector side, at least a part of the conductive member forms a conductive path electrically connecting the first principal surface to the second principal surface, and the conductive path is in contact with the active material in the periphery of the conductive path, at least a part of the surface of the active material is coated with a coating agent that includes a coating resin and a conduction assisting agent, and an electrolyte solution contained in the electrolyte layer or the two electrodes having different polarity is a gel phase electrolyte.
