Researchers uncover hidden material phases that could boost batteries and solar fuels
A study in Nature Communications reports previously unknown intermediate material phases that may improve clean‑energy technologies.
By Felo News Desk · Published
Scientists at the University of Warwick have identified previously unknown intermediate material phases that emerge during the heating of specially designed molecular precursors, a discovery reported by ScienceDaily on 9 October 2026.
What happened
The research team used "single‑source precursors"—molecules that contain all the elements needed to form a solid material—and monitored their transformation as temperature increased. By focusing on the transient stages that appear before the final product, the team captured several new phases that are typically missed in conventional synthesis.
What the reports add
ScienceDaily notes that one of the newly observed phases is a kinetically stabilised form of bismuth vanadate (BiVO₄), designated β‑BiVO₄. This polymorph differs in atomic arrangement from the well‑studied β‑BiVO₄ and exhibits a significantly larger band gap, which alters its interaction with light. The larger band gap could enable new ways to tune the material for solar‑fuel production, catalysis and electronics.
The article also mentions another hidden material discovered in the same experiments that can store large amounts of lithium, suggesting possible applications in next‑generation batteries, although details on its composition and performance are not provided.
What was said
Dr. Sebastian Pike of the Department of Chemistry at the University of Warwick explained, "When materials are made by heating, scientists usually focus on the final product, the 'B' that results from 'A.' But this study shows that there are many fascinating stages in between 'A' and 'B,' and these hidden steps could be just as important," as quoted by ScienceDaily.
How it came about
The approach builds on earlier work that often overlooks intermediate phases because researchers tend to concentrate on the end material. By deliberately tracking the evolution of the precursors, the Warwick team revealed pathways to phases that are difficult or impossible to obtain through standard methods. The findings were published in the journal Nature Communications.
