Prussian Blue Analogue-Templated Nanocomposites for Alkali-Ion Batteries: Progress and Perspective

Abstract

Highlights The synthetic protocols of various Prussian blue analogue (PBA)-templated nanocomposites are discussed. Alkali-ion storage mechanisms based on intercalation, alloying, or conversion reactions are analysed. The properties of PBA-templated nanocomposites in alkali-ion batteries (AIBs) are evaluated and compared to outline the structure–activity correlation. Perspectives for the future development of PBA-templated AIB electrodes are envisaged.
