NEGATIVE POLE FOR LITHIUM CELL

摘要

PURPOSE:To improve the charge/dischaege characteristic of the negative pole for Li cell, by bearing Li on a porous Al. CONSTITUTION:Li is employed as the negative active substance while the substance performing the reversible electrochemical reaction with Li ion is employed as the positive pole substance where the electrolytic substance is chemically stable for the positive pole substance and Li while the following negative pole is employed in the Li cell which is the substance where the Li ion is movable. In other word, a porous material Al having the porosity higher than 17/2.54cm bearing Li is employed in this primary and secondary cells as the negative pole. With this negative pole, the drop-out of Li and the occurrence of dendrite can be prevented resulting in the excellent discharge/charge characteristic.
