LITHIUM ION ELECTROCHEMICAL CELL

摘要

A lithium ion cell having an amount of a Group 1 element between the positive electrode (14) and the negative electrode (10) is described. The Group 1 element can be on a surface of an electrode separator (18) as a deposit. The Group 1 element can increase the charging capacity of the cell, eliminate the irreversible capacity of the cell, improve the rechargeable cell cyclability, or increase the charging reversibility of the cell.
