<P>PROBLEM TO BE SOLVED: To provide a high-power non-aqueous electrolyte secondary battery having stable cycle characteristics. <P>SOLUTION: The non-aqueous electrolyte secondary battery includes: positive collectors 5, 11; positive electrodes 7, 12 containing a positive electrode active material 6 applied to the positive collectors 5, 11; negative collectors 2, 9; and negative electrodes 4, 10 containing a negative electrode active material 3 applied to the negative collectors 2, 9. The non-aqueous electrolyte secondary battery further includes: a separator 8 having ion permeability and electrical insulation properties; positive electrodes 7, 12; negative electrodes 4, 10; and a non-aqueous electrolyte 16 in which the separator 8 is soaked. At least either the positive electrode or the negative electrode includes a first transmission electrode having a first void formed therein, wherein the first void transmits the non-aqueous electrolyte 16, which is absorbed from an end portion in a direction perpendicular to a direction along which the positive and negative electrodes are aligned to be transmitted inside, in the direction along which the positive and negative electrodes are aligned. At least either the positive electrode or the negative electrode includes a second transmission electrode having a second void formed therein, wherein the second void transmits the non-aqueous electrolyte 16 from one side surface to another side surface in the direction in which the positive and negative electrodes are aligned. <P>COPYRIGHT: (C)2011,JPO&INPIT |
