SEPARATOR FOR ELECTROCHEMICAL CELLS |
摘要 |
This invention relates to a separator for non-aqueous electrochemical cells and in particular lithium/manganese dioxide cells. It has been discovered that a polypropylene microporous film having a thickness greater than one mil and voids greater than 50% by volume, has beneficial properties without the concomitant problems generally associated with separators having open structures. |
