Title: Cell
Inventor: KEZUKA KOICHIRO
IPC: H01M10/05
Filed: 2000-07-03
Abstract: PROBLEM TO BE SOLVED: To provide a cell enabling to obtain a good electrolyte and raise its characteristics. SOLUTION: A cell element 20 in which a positive electrode 21 and a negative electrode 22 are laminated sandwiching a separator 23 in between, inside an outer packing 30, is equipped. An electrolyte containing a high polymer molecular compound compounded by polymerization of a monomer in a separator 23, is impregnated. Since the synthesis of the high polymer molecular compound may be checked if Cu exists, a negative electrode electricity-collector-body layer 22b is constituted from a foil of a metal (for example, Ni, Cr, and Au) not forming an alloy with Li, excepting Cu, or Cu foil covered with the metal. By this, even if the synthesis of the high molecular compound is carried out after assembling the cell, the polymerization can be well advanced and a residual monomer content can be reduced. Therefore, even if the charging/discharging is repeated, the decomposition or the reaction of the monomer is inhibited, and degradation of the cell characteristics can be prevented.
