Abstract: A prismatic nonaqueous electrolyte secondary battery includes a flat winding electrode assembly formed by winding an elongated positive and negative electrodes with an elongated separator interposed therebetween, and an outer body storing the flat winding electrode assembly and a nonaqueous electrolyte. The positive electrode includes a positive electrode substrate exposed portion formed along a longitudinal direction. The negative electrode includes a negative electrode substrate exposed portion formed along a longitudinal direction. The nonaqueous electrolyte contains at least one of a lithium salt having an oxalate complex as an anion and lithium difluorophosphate (LiPF2O2) at the time of making the nonaqueous electrolyte secondary battery. The flat winding electrode assembly has eight or more layers of a winding portion formed only of the separator in its central portion. This battery can allow a nonaqueous electrolyte having a high viscosity to easily penetrate the inside of a flat winding electrode assembly.
