Document Type and Number:
Japanese Patent JP2639935
Kind Code:
B2
Abstract:
PURPOSE:To improve the cycle characteristic of a secondary cell by using the Li treated with ring ether, wherein trifluoromethane sulfonic acid Li is dissolved, as a negative electrode. CONSTITUTION:A nonaqueous electrolyte secondary cell consists of a negative electrode 1, a negative electrode can 2, a positive electrode 4, a positive electrode can 5, a separator 7 and an insulating packing 8. Then, Li, which is conductively treated in a treatment liquid composed of various kinds of ring ether, in which (one mol/l) of trifluoromethane sulfonic acid lithium LiCF3SO3 is dissolved, and left alone at 60 deg.C for one week, is used as the negative electrode.
