摘要

摘要三长石结构的 NaMnPO4 被认为是钠离子电池正极活性材料的最佳候选材料。然而，NaMnPO4 往往会生成不具有有效钠离子传导路径的钠钙石相。因此，它需要经过几个复杂的反应步骤（如离子交换），才能获得具有有效钠离子传导路径的闪锌矿相。本研究提供了一种在温和条件下通过水溶液中的酸碱反应直接合成三苯基 NaMnPO4 的有效方法。

Effective synthesis of triphylite NaMnPO4 through acid–base reaction in aqueous solution

Abstract 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.
