Engineering radical polymer electrodes for electrochemical energy storage …
2.3. Radical-bearing polymers. Compared to conducting polymers (0.1–0.92 charges per monomer) [91], [117], radical-bearing polymers have a consistently high doping level (0.8–0.9 radicals per monomer) for charge storage as the radical is covalently bonded to the polymer backbone rather than part of the backbone [63].

Two-electron conversion nitroxide radicals-based electrode synergistically enhancing charge storage …
The deposited nitroxide radicals and MXene binder resulted in the synergistic enhancement of charge storage within WISE, leading to the well-improved discharge capacity of the composite electrode. Besides, the nitroxide radicals on the surface of porous carbon exhibited a two-step two-electron redox reaction, which greatly …
Stable Radical Materials for Energy Applications | Annual Reviews
Although less studied than their closed-shell counterparts, materials containing stable open-shell chemistries have played a key role in many energy storage and energy conversion devices. In particular, the oxidation-reduction (redox) properties of these stable radicals have made them a substantial contributor to the progress of organic batteries. Moreover, …
5.1: Roots and Radicals
Recall that a square root1 of a number is a number that when multiplied by itself yields the original number. For example, 5 is a square root of 25, because 52 = 25. Since ( − 5)2 = 25, we can say that − 5 is a square root of 25 as well. Every positive real number has two square roots, one positive and one negative.
