Effective synthesis of triphylite NaMnPO4 through acid–base reaction in aqueous solution
Triphylite structure NaMnPO4 is expected to be an excellent candidate as the positive active material of a Na-ion battery. However, NaMnPO4 tends to generate a maricite phase that does not have a valid sodium-ion conduction path. Thus, it undergoes several complex reaction steps, such as ion exchange, to obtain the triphylite phase to have an effective sodium-ion conduction path. This study provides an effective direct synthesis method for triphylite NaMnPO4 through an acid–base reaction in aqueous solution under mild conditions.

Alkali Metal–Metal Exchange Reaction for Effective Synthesis of Functional Phosphate Salts
AMPO4 and MPO4 systems (A = alkali metal, M = metal) exhibit various optical and electrochemical functions. This study shows that such systems can be synthesized via an alkali metal–metal exchange reaction between A3PO4 and the metal salt of an acid with lower pKa than phosphoric acid. This method significantly improves the material designs and syntheses of various phosphate salts.
