| 20120328912 | WINDING ASSEMBLY FOR ELECTROCHEMICAL CELLS, METHODS OF MAKING THE WINDING ASSEMBLY, AND THE ELECTROCHEMICAL CELL - A winding assembly including positive and negative electrodes and a separator sheet wound in an overlying relationship such that the separator sheet is positioned between the positive and negative electrodes, and such that an exposed edge of the positive electrode is spaced longitudinally from an unexposed edge of the negative electrode at one end, and such that an exposed edge region of the negative electrode is spaced longitudinally from an unexposed edge of the positive electrode at an opposite end, and wherein a portion of the positive electrode proximate to the exposed edge of the positive electrode comprises a first plurality of apertures and a portion of the negative electrode proximate to the exposed edge of the negative electrode comprises a second plurality apertures. | 12-27-2012 |
| 20120251876 | ENERGY STORAGE DEVICES COMPRISING CARBON-BASED ADDITIVES AND METHODS OF MAKING THEREOF - The present invention is directed to energy storage devices, such as lead-acid batteries, and methods of improving the performance thereof, through the incorporation of one or more carbon-based additives. | 10-04-2012 |
| 20120171564 | ADVANCED GRAPHITE ADDITIVE FOR ENHANCED CYCLE-LIFE OF LEAD-ACID BATTERIES - An Advanced Graphite, with a lower degree of ordered carbon domains and a surface area greater than ten times that of typical battery grade graphites, is used in negative active material (NAM) of valve-regulated lead-acid (VRLA) type Spiral wound 6V/25 Ah lead-acid batteries. A significant and unexpected cycle life was achieved for the Advanced Graphite mix where the battery was able to cycle beyond 145,000 cycles above the failure voltage of 9V in a non-stop, power-assist cycle-life test. Batteries with Advanced Graphite also showed increased charge acceptance power and discharge power compared to control groups. | 07-05-2012 |
