Prussian White Cathode Materials for All-Climate Sodium-Ion Batteries
Ruitao Sun, Ya You
Abstract
Prussian white (PW) is considered one of the most promising cathode materials for sodium-ion batteries because of its large ion diffusion channels, low lattice strain, facile preparation, nontoxicity, and low cost. At present, research on PW mainly focuses on optimizing the material's structures for the ambient environment yet less on its practical application under extreme temperatures. In this Spotlight, we intend to offer progress we have made in developing PW cathode materials working over wide temperatures in terms of intrinsic feasibility and development prospects. These findings provide a direction to promote the practical viability of PW under extreme conditions.
