摘要

通过 NH4MPO4-H2O（M = Mn、Mn/Fe）与 AcONa-3H2O 或 AcOLi 的低温反应，分别分离出了相纯的 NaMPO4（M = Mn、Mn/Fe；与三苯基石同型）和 Li（Mn/Fe）PO4。在半电池中进行的电化学测试表明，与金属 Na 相比，Na 基化合物的电化学活性较差，而类似合成的 Li 对应物在 Na 电池中的循环性能良好。本文讨论了橄榄石家族相关成员的合成特征、晶体结构和性质。

Low-temperature synthesis in the dittmarite–sodium acetate trihydrate system: electrochemical activity of M3+/M2+ redox couples in AMPO4 (A = Na, Li; M = Mn, Mn/Fe)

Phase-pure NaMPO₄ (M = Mn, Mn/Fe; isotypic to triphylite) and Li(Mn/Fe)PO₄ were isolated as a result of the low- temperature reaction between NH₄MPO₄·H₂O (M = Mn, Mn/Fe) and AcONa·3H₂O or AcOLi, respectively. Electrochemical tests in half-cells revealed that Na-based compounds exhibit poor electrochemical activity vs. metallic Na, while the similarly synthesized Li counterpart demonstrates decent cycling in Na cells. The synthetic features, crystal structures and properties of related members of the olivine family are discussed.

期刊介绍： Mendeleev Communications is the journal of the Russian Academy of Sciences, launched jointly by the Academy of Sciences of the USSR and the Royal Society of Chemistry (United Kingdom) in 1991. Starting from 1st January 2007, Elsevier is the new publishing partner of Mendeleev Communications. Mendeleev Communications publishes short communications in chemistry. The journal primarily features papers from the Russian Federation and the other states of the former USSR. However, it also includes papers by authors from other parts of the world. Mendeleev Communications is not a translated journal, but instead is published directly in English. The International Editorial Board is composed of eminent scientists who provide advice on refereeing policy.
