ELECTRONICS made a huge leap forward when the delicate and temperamental vacuum tube was replaced by the robust, reliable transistor. That change led to the now ubiquitous silicon chip. As a consequence, electronic devices have become vastly more powerful and, at the same time, have shrunk in both size and cost. Some people believe that a similar change would happen if rechargeable batteries could likewise be made into thin, solid devices. Researchers are working on various ways to do this and now one of these efforts is coming to fruition. That promises smaller, cheaper, more powerful batteries for consumer electronics and, eventually, for electric cars.
