High Power Organic Radical Battery for Information Systems(Electrochemical of Organic Materials)( Recent Progress in Organic Molecular Electronics)

We have developed a high-power organic radical battery for information technology equipment such as personal computers (PCs). The battery provides several minutes of backup power without an external uninterrupted power source. Since the built-in battery makes energy conversion from AC to DC, or DC to AC, unnecessary, it protects equipment from power failure with no loss of energy. The fabricated battery shows a high power density of 1 kW/L and is capable of driving a desktop PC for several minutes. The use of purely organic polyradicals, poly (2,2,6,6-tetramethylpiperidinyloxy mathacrylate), for the cathode active material opens up a new field of high power density, environmentally friendly batteries.
