The first lithium manganese oxynitride, Li7.9MnN5-O-y(y): preparation and use as electrode material in lithium batteries

The first lithium manganese oxynitride, Li7.9MnN5-yOy, 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).
