(A) CV profile of TPA under Ar atmosphere. (B) Stability of TPA against O2− and 1O2. (C) DMA concentration profiles in charging with SP or RuO2 cathode and TPA. (D–F) Gas evolution during charging with RuO2 + TPA, SP + TPA, and SP. Red and blue curves represent the respective evolution rates of O2 and CO2. (G) 1H-NMR spectra of the electrolytes at the initial state and after 10 cycles in DMSO-d6. (H) Quenching efficiencies of electron-rich TPA analogs.
