Description
Yong-Gang Sun and co-authors review a promising sodium battery material from crystal to factory. Their 2026 survey covers an iron-based cathode known as NFPP. It is prized because it barely swells as sodium moves in and out, conducts ions quickly through an open frame, and uses cheap, abundant iron.
One flaw dogs it: during synthesis, two rival phases compete to form, and one is electrochemically dead weight. The review walks through the crystal structure and storage mechanism, then the fixes researchers have tried: off-recipe ratios, built-in defects, added elements, swapped ions, and layered designs. Each is judged on how it beats the impurity problem and speeds the chemistry. Factory progress, full-cell results, costs, and open questions close the survey.
