I want to use a high voltage cathode in my battery and I also want to suppress oxygen evolution at high voltage. Can you guys give me some reference about understanding how to suppress oxygen evolution in aqueous electrochemical system like batteries.
No way. The thermodynamical stability window of water solutions is 1.23V. A high voltage cathode will decompose water in any cases. IMHO
Thanks, Klyueu,
I know and agree with you. But, as you know, it is possible to increase Kinetic barriers to increase stability window. My question is actually about these kind of techniques to introduce kinetic barriers to suppress oxygen evolution to higher voltage.
Yep, I guess it possible to increase the over potential by choosing a. different current collector b. coating of high over potential material like PbO etc 3. Mixed solvent with carbonate PC mixes well with water .. try these there aspects you may get improved results..
Thanks
