Scientists are trying to develop light ecofriendly and inexpensive batteries consisting entirely of nonmetal parts
No Silicon Valley companies were among the seven that made initial public stock offerings during the week. But A123 Systems, a Massachusetts-based maker of rechargeable lithium-ion Sony-VGP-BPS2-Battery systems for customers such as Black & Decker and Chrysler, closed with a 45 percent first-day climb from its $13.50 IPO price on its debut Thursday.

The most promising materials include so-called conductive polymers or "plastic electronics." One conductive polymer, polypyrrole (PPy), shows promise, but was often regarded as too inefficient for commercial HP DV9000 Battery .
The 13.1-inch model, not surprisingly, is called the Envy 13. In the brief encounter I had with this model while working in an office suite, its 1366-by-768-pixel screen looked sharp--but I didn't have a chance to subject it to PC World's usual image-quality tests, so this is merely an initial impression.
