    Abstract: A battery separator for a lithium-ion secondary battery is a microporbus membrane with an adjuvant. The microporous membrane is made of a thermoplastic, and has a thickness of 25 μm or less. The adjuvant, in an effective amount, is mixed into the membrane or coated thereon. The adjuvant is a material adapted to reduce or eliminate energy concentrations around the separator. The energy concentration is sufficient to initiate a reaction of the components of the lithium ion secondary battery.

    Abstract: A method for generating a standard cell layout pattern for standard cell placement in an integrated circuit uses a congestion map. First, congestion zones are identified in a congestion map generated by an Electronic Design Automation (EDA) application. Next, routing tracks data corresponding to bounding boxes belonging to the congestion zones are used to calculate values of average vertical and horizontal congestion. Subsequently, a value of modified standard cell density is calculated based on the values of average vertical and horizontal congestion, and an unmodified standard cell density. The dimensions of a layout pattern unit are calculated using the value of the modified standard cell density and the width of standard cells. Various layout pattern units then are placed adjacent to one another to form a standard cell layout pattern.

    Abstract: A battery separator is a microporous membrane. The membrane has a major volume of a thermoplastic polymer and a minor volume of an inert particulate filler. The filler is dispersed throughout the polymer. The membrane exhibits a maximum Z-direction compression of 95% of the original membrane thickness. Alternatively, the battery separator is a microporous membrane having a TMA compression curve with a first substantially horizontal slope between ambient temperature and 125° C., a second substantially horizontal slope at greater than 225° C. The curve of the first slope has a lower % compression than the curve of the second slope. The curve of the second slope is not less than 5% compression. The TMA compression curve is graphed so that the Y-axis represents % compression from original thickness and the X-axis represents temperature.
