The first lithium manganese oxynitride, Li7.9MnN5 − yOy: preparation and use as electrode material in lithium batteries

Abstract

The first lithium manganese oxynitride, Li_7.9MnN_{5 − y}O_y, was obtained by solid state reaction of binary nitrides and lithium oxide under nitrogen flow. It is an interesting candidate for negative electrode material in lithium ion batteries yielding a reversible capacity of 310 mAh g⁻¹.
