Abstract
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.
