NEC Develops Radical Battery

NEC Corp. of Tokyo, Japan, is developing a high-power organic radical battery (ORB) used to protect IT equipment from losing data during power supply interruption. The film packed ORB (size: 55×43mm and 4mm thick) demonstrates a maximum power of 35W and its four series-connected cells are capable of driving a 140W class desktop PC in the event of power supply interruption.

ORB uses the electrochemical reaction of organic radical compounds. This technology was initially proposed by NEC in 2001. To date, NEC has succeeded in synthesizing a polyradical of the modified PTMA, or “2,2,6,6-tetramethylpiperidinoxy-4-yl methacrylate,” with excellent durability. Due to the high reactivity and reversibility of the radical reaction, the organic radical battery demonstrates extremely high power density and good cycleability making it suitable for a range of next generation applications.

As a built-in, ORB makes obsolete the need for energy conversions from AC to DC, or DC to AC, and it realizes protection of equipment from power failure with no loss of energy. Environmentally friendly, the ORB consists of organic polymer which contains no harmful heavy metals, Hg, Pb, or Cd, etc. ORB has been confirmed to be inflammable and non-explosive, making it extremely safe.
