ELECTRODE FILM, ELECTRODE, METHOD FOR MANUFACTURING THE ELECTRODE, AND ELECTRICAL STORAGE DEVICE

摘要

Provided is an electrode film, wherein an active material having an average particle diameter of 2 µm or more but not more than 50 µm and conductive ion-containing inorganic particles having an average particle diameter of 1 nm or more but less than 2 µm are contained, and the active material is bound thereon by means of the inorganic particles.  An electrode wherein the electrode film is laminated on a collector is also provided.  Furthermore, an electrical storage device having the electrodes is also provided.  In the electrical storage device, two electrodes are arranged such that the electrode films face each other.  The both electrodes are wound or laminated in a state where a separator is provided between the electrode films, and the electrodes and the separator are sealed in a metal case with an electrolytic solution.
