Description
Zaineb Mighri and co-authors present 2026 materials research on phosphate compounds tuned for energy storage. The team made a family of crystals in which nickel and cobalt trade places inside a chromium phosphate framework. Potassium ions sit in tunnels within the structure, and swapping the two metals changes how the material stores and moves electric charge.
All versions behaved as stable paraelectric materials, meaning they polarize under voltage without holding a permanent charge. Adding cobalt raised the material's ability to store charge while keeping energy losses low. Built into graphite-based supercapacitors, the cobalt-only version performed best, reaching a specific capacitance of 447 farads per gram in the team's tests. The authors present metal substitution as a practical dial for designing electrodes that combine high storage with fast power delivery.
