Organic batteries are an alternative to the metal reaction battery technologies, and much research is taking place in this area. Waseda University was approached by NEC in 2001, and began to focus on the organic batteries. In 2002, NEC researcher presented a paper on Piperidinoxyl Polymer technology, and by 2005 they presented an organic radical battery (ORB) based on a modified PTMA, poly(2,2,6,6-tetramethylpiperidinyloxy-4-yl meth-acrylate).
In 2006, Brown University announced a technology based on polypyrrole. In 2007, Waseda announced a new ORB technology based on "soluble polymer, polynorborene with pendant nitroxide radical groups."
