| Much smaller. Much lighter. Much better performance. As digital products such as mobile phones, notebook PCs, digital cameras, MP3 players and palm-held devices become more a part of everyday life, consumers are more attuned to the work be in done to reduce the size and weight of these products while enlarging their capacity and functionality. Further evolution of such products makes the issue concerning efficient use of energy more critical. They are required to provide advanced functions for longer operating time and to handle more severe conditions. Now, there is a strong need for energy devices which can deliver higher energy/power density to not only these compact gadgets but also various other types of products. |
