Abstract
Provided are a non-aqueous electrolyte secondary battery having excellent high-temperature durability and capable of reducing the initial percent defective and a process for producing the same. The non-aqueous electrolyte secondary battery includes: a positive electrode containing a positive-electrode active material; negative electrode containing a negative-electrode active material; a non-aqueous electrolyte; and a porous layer provided on a surface of the positive electrode, wherein the porous layer contains inorganic solid electrolyte particles having a crystalline structure of rhombohedral crystal (R3c) with lithium ion conductivity represented by Li1+x+yAlxTi2-xSiyP3-yO12 (where 0≦x≦1 and 0≦y≦1) and an aqueous binder.
