Preparation and Investigation of a Novel Organic Polymer Consisting of 2,2,6,6‐Tetramethylpiperidine‐N‐oxy as a Cathode Active Material in Li‐Ion Batteries

In the present study, a novel organic polymer consisting of 2,2,6,6‐tetramethylpiperidine‐N‐oxyl group as an electroactive center is employed by synthesizing it from a commercially ready polymer. An investigation on electrochemical and battery properties of this material as a cathode active material in different electrolyte salts was conducted. A coin cell shows a discharge capacity of 40 mAh g −1 at 1 C which is 76% of its theoretical capacity. It is observed that there is no significant decrease in capacity value even at 2 C and 5 C which indicates that it is applicable for the high‐power applications. Besides, a good cycle stability is obtained with the organic radical battery.
