摘要： Several embodiments of a microporous battery separator for lithium rechargeable batteries and/or related methods of making and/or using such separators are disclosed. A dry process battery separator or membrane separator exhibits a thickness that is less than about 14 μm and has increased strength performance as defined by reduced splittiness. The mode of splitting failure has been investigated, and the improvement in splittiness quantified by a test method known as the Composite Splittiness Index (CSI).

摘要： A method for improving physical properties of a separator in which is capable of increasing insulation, tensile strength and elongation. The separator also has improved physical properties through the above method. Particularly, the present invention is applied to a separator that has already manufactured. After forming a double bond in the separator that has already manufactured, crosslinking may be formed through the double bond or by adding a separate crosslinking initiator.
