Patent ID: 7914921

Claim:
An enhanced separator for a battery, comprising: a separator layer having a first dimension and a second dimension; and two to five resistive layers, wherein each of the resistive layers has a first dimension and a second dimension and wherein the resistive layers are disposed on said separator layer; wherein the magnitude of each of the first dimensions of a plurality of said resistive layers is less than the magnitude of the first dimension of said separator layer; the magnitude of the second dimension of said resistive layers is equal to the magnitude of the second dimension of said separator layer; the plurality of said resistive layers each comprising a separate first independent part and a separate second independent part; said first independent part and second independent part each having a first dimension and a second dimension; and the sum of the magnitude of the first dimension of said first independent part and the magnitude of the first dimension of said second independent part is less than the magnitude of the first dimension of said separator layer.
