High Power Organic Radical Battery for Emergency Power Source

Organic radical battery (ORB) has been attracted much interest as a new class of rechargeable battery with excellent high-rate charging-discharging properties. This technology was initially reported by us in 2001[1]. To date, we have succeeded in synthesizing a durable polyradical of 2,2,6,6 tetramethylpiperidine-4-yl-oxy methacrylate (PTMA) derivatives. Here we describe the preparation and properties of a high power ORB cells and their application to an emergency power source for IT equipments.
