Manganese(III) fluoride Manganese(III) fluoride Manganese(III) fluoride (also known as Manganese trifluoride) is the inorganic compound with the formula MnF. This red/purplish solid is useful for converting hydrocarbons into fluorocarbons, i.e., it is a fluorination agent. It forms a hydrate and many derivatives. MnF can be prepared by treating a solution of MnF in hydrogen fluoride with fluorine: It can also be prepared by the reaction of elemental fluorine with a manganese(II) halide at ~250 °C. Like vanadium(III) fluoride, MnF features octahedral metal centers with the same average M-F bond distances. In the Mn compound, however, is distorted (and hence a monoclinic unit
Lithium ion manganese oxide battery made of alternating layers of lithium ions and lithium and manganese ions in a 1:2 ratio, similar to the layered structure of . Although is electrochemically inactive, it can be charged to a high potential (4.5 V v.s Li) in order to undergo lithiation/de-lithiation. However, extracting lithium from at such a high potential results in loss of oxygen from the electrode surface which leads to poor capacity and cycling stability. One of the main research efforts in the field of lithium-manganese oxide electrodes for lithium-ion batteries involves developing composite electrodes using structurally integrated layered and spinel , with a chemical
