ABSTRACT:
The present invention provides a nonaqueous secondary battery having a high discharge potential, a high discharge capacity, a good charge-discharge cycle characteristics and good high current charge-discharge characteristics. That is, a novel nonaqueous secondary battery is disclosed, comprising a sheet-shaped positive electrode having at least one layer containing a lithium-containing transition metal compound as a positive electrode material, a sheet-shaped negative electrode having at least one layer containing a negative electrode material capable of intercalating and deintercalating a lithium ion, a porous separator comprising polyolefines, and a nonaqueous electrolyte containing a lithium salt, wherein at least one of said sheet-shaped negative electrode and said sheet-shaped positive electrode comprises three or more layers applied to a current collector and the two layers furthest from said current collector each contain an insulating solid fine particle which doesn't substantially intercalate and deintercalate a lithium ion.
