At least that is what I gathered from this article... ------------- Never Too Thin or Too Powerfulmobilecomputing.com While it might not be an engineering breakthrough, Valence Technology Inc. has pulled off a coup that could change the way we power our mobile equipment. The Henderson, NV, company recently consolidated all the patents and trademarks for lithium polymer (Li-poly) batteries from Telcordia Technologies Inc. (formerly Bellcore, the research arm of the Baby Bells) for stock worth roughly $50 million. The stock deal resolves a mutually restrictive situation that kept Li-poly cells out of mainstream use, says Lev Dawson, chairman and CEO at Valence. While Telcordia/Bellcore mastered the basic technology, Valence perfected the processes needed to mass produce the cells. "We had the core patents for the technology," says Vassilis G. Keramidas, Telcordia's vice president of formative technologies. "[Valence] debugged a lot of the manufacturing issues." The deal involved 42 U.S. patents, 15 license agreements and the PLiON trademark. Consolidating the patents not only creates a Li-poly powerhouse but provides a single source from which an interested company can license any or all the technologies and processes needed to make Li-poly batteries. Valence's approach to Li-poly batteries rests on using a unique mix of materials to achieve lower cost, greater safety and an environmentally friendly product. Instead of relying on lithium cobalt oxide, which runs about $22 a pound for the cathode, Valence switched to lithium manganese oxide, which costs half as much and is more durable. Says Dawson, "Our battery costs drop by 30 percent, and we get 1,000 recharge cycles at 80 percent capacity with [lithium] manganese oxide." Plus, using lithium manganese oxide circumvents the disposal problems of lithium cobalt cells, which contain heavy metals that are illegal to throw in the garbage. Lithium polymer already has moved from cost-is-no-object applications, like satellites and weapons, to mobile phones and could be headed for notebooks by the end of the year. "We've made some ergonomic shapes," Dawson continues. Footprint batteries Ð which are just one-quarter-inch thick but cover most or all of a notebook's base Ð already are being made. For example, Valence's Model 74 cell has a mobile-friendly, 2.6 by 5.6-inch outline and can be made in varying thicknesses, depending on the type of system incorporating it. At about one-tenth-inch thick, the battery holds 2,080 milliamp-hours of capacity and weighs little more than 2 ounces, ideal for an ultralight notebook. Double its thickness, and you have a 4,170 milliamp-hour battery that would be perfect for a full-size notebook. Ð William Terdoslavich
