A change in architecture is promising to close the gap between semiconductor technology and battery technology, which has traditionally lagged behind semiconductors due to its dependence on unchangeable chemical reactions. Instead of storing charge in a main battery—then doling it out to individual devices on demand—a new breed of hybrid capacitor/battery is storing just enough energy for an adjacent device's exclusive use. Ioxus Inc. (Oneonta, N.Y.) says it is solving the "battery problem" by defining a new distributed-energy architecture.
