    Abstract: A secondary battery configured so as to comprise: a plurality of positive electrodes each including a positive electrode core and a positive electrode active substance disposed on the positive electrode core; a plurality of negative electrodes each including a negative electrode core and a negative electrode active substance disposed upon the negative electrode core; at least one separator; and an adhesive coated so as to have a substantially constant area density on at least one side surface in the thickness direction of the separator. The secondary battery includes a laminated section in which the positive electrodes and the negative electrodes are alternately stacked, having the separator therebetween. The area of adhered sections adhered by the adhesive is greater on the outside in the lamination direction of the laminated section than on the inside in the lamination direction.

    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.
