<P>PROBLEM TO BE SOLVED: To provide a nonaqueous electrical storage device which is of large capacity and of high voltage, and is excellent in reliability. <P>SOLUTION: A nonaqueous electrical storage device 11 is constituted so that an electrode stack 51 composed by laminating a positive pole 21, a negative pole 31, and a separator 41 is housed in a case 61, and organic electrolyte is injected into the case 61. In the negative pole 31, a negative pole side through hole 36 is formed. In the positive pole 22, in the position corresponding to the negative pole side through hole 36, a positive pole side through hole 26 of which the area is larger than the negative pole side through hole 36 or an electrode nonexistence region 27 is formed. In the negative pole side through hole 36, a lithium metal 16 for pre-doping is arranged. <P>COPYRIGHT: (C)2009,JPO&INPIT |
