Sol-gel-modified membranes for all-organic battery based on bis-(tert-butylphenyl)nitroxide

It has been shown that sol-gel modification of Nafion membrane with amino-containing silica nanoparticles followed by neutralization converting the membrane in the salt form prevents decomposition of the model redox-active compound, bis(tert-butylphenyl)nitroxide, and suppresses its crossover yet maintaining sufficient permeability of a supporting electrolyte in acetonitrile solution. Bis(tert-butylphenyl)nitroxide is stable under the operation conditions of the redox flow battery assembled with Celgard membrane.
