PURPOSE:To prevent a sudden increase of the inner resistance during the operation, by fixing a negative electrode consisting of lithium or a lithium alloy to armoring cans through collectors, and securing the electrical connection between the negative electrode and the armoring cans. CONSTITUTION:As a negative electrode active substance, lithium or a lithium alloy is used. In this case, there is no restriction on the type of the lithium alloy, but an alloy of aluminum and lithium is especially preferable to have a good negative electrode property and a good plastic performance. Moreover, the negative electrode 4 is fixed to armoring cans 1a and 1b through collectors 6 and 9. In this case, there is no restriction on the material of the collectors 6 and 9, and an adequate form of stainless steel, nickel, aluminum, platinum, and carbonic conductor, for example, are available for this purpose, a stainless steel being especially preferable. Since a cell with the negative electrode of lithium or a lithium alloy has a high voltage, and a high energy density with little self-discharge, the stainless steel is preferable to be thin, being 5 to 100mum normally. |
