<P>PROBLEM TO BE SOLVED: To provide an accumulator that achieves high productivity by preventing or suppressing the occurrence of variations in ion supply speed when doping lithium-ions from a lithium-ion supply source. <P>SOLUTION: The accumulator has the following configuration. The accumulator includes an electrode unit, a lithium-ion supply source, and an electrolyte. The electrode unit includes an electrode stack in which a positive electrode, having a positive electrode active material capable of reversibly carrying lithium ions or anions, and a negative electrode, having a negative electrode active material capable of reversibly carrying lithium-ions, are stacked via a separator. The lithium-ion supply source is provided so as to be in contact with one face of the separator. The electrolyte is composed of an aprotic organic solvent electrolyte solution of a lithium salt. The lithium-ions are doped into the negative electrode or the positive electrode by an electrochemical contact between the negative electrode or the positive electrode and the lithium-ion supply source. A tape having an adhesive layer formed on one face is provided on the other face of the separator so as to overlap with the lithium-ion supply source via the separator. A plurality of holes are formed so as to penetrate through in the thickness direction of the tape and/or the adhesive layer. <P>COPYRIGHT: (C)2011,JPO&INPIT |
