Abstract:
A non-aqueous secondary battery having, in a casing, an electrode plate laminate having at least a positive electrode and a negative electrode in which an active material layer is fixed to at least one surface of a current collector and a separator having an electrolyte solution permeability interposed between the active material layers of both of the electrodes, with a non-aqueous electrolyte solution being poured and sealed in the casing, whereinthe separator is an aggregate layer of insulating material particles formed by bonding insulating material particles to each other by a binder and fixed to at least one of the positive electrode and the negative electrode, and an end face of at least one of the positive electrode active material layer and the negative electrode active material layer is at least partially coated with the aggregate layer of insulating material particles.
