• 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.
