Description
Madeline Van Winkle, Stephen House, Yuxiang Peng, and a wider team wrote this research paper, published in 2025. It watches cobalt oxide particles break down as they are cycled through the heat-driven chemical reactions used to store energy.
Metal oxides are strong candidates for storing heat over long periods, but most tests look at bulk material. The team used an electron microscope that can heat samples and read their chemistry at the same time. They found the particles reacted much more slowly after the first cycle, because heat fused them into denser clumps. Humid air shifted the temperatures at which reactions switched, but did not stop the clumping. The authors say lasting gains must come from how the particles are made or shaped.
