KeywordsSolid electrolyte / SrCoOx / Protonation / Redox reaction
Outline of Research at the Start

SrCoOx-based electrochemical devices have been proposed, but solid-state device that can be operated from HSrCoO2.5 to SrCoO3 has not been demonstrated thus far due to the absence of appropriate solid electrolyte. Here we utilize CAN as the electrolyte to realize the tri-state decice.

Outline of Annual Research Achievements

Several SrCoOx-based electrochemical devices have been proposed, but solid-state protonation from SrCoO2.5 to HxSrCoO2.5 (x = 1, 1.5, and 2) at room temperature has not been demonstrated thus far due to the absence of an appropriate solid electrolyte. I demonstrated a solid-state electrochemical protonation of SrCoO2.5 using mesoporous amorphous 12CaO・7Al2O3 (CAN) film as the solid electrolyte. The crystalline phase discretely changed from SrCoO2.5 to HSrCoO2.5, H1.5SrCoO2.5, and H2SrCoO2.5 through formation of an intermediate phase of H1.25SrCoO2.5. H1.5SrCoO2.5 was colorless transparent and showed weak ferromagnetism. The present results indicate that the CAN film can be used as the solid electrolyte for the protonation treatment of TMOs. This work has been published in ACS Appl. Electron. Mater. 3, 3296-3300 (2021). Further, I created a solid-state thermal transistor using SrCoOx and YSZ and submitted a patent.
