A monoclinic polymorph of sodium birnessite for ultrafast and ultrastable sodium ion storage

A monoclinic polymorph of sodium birnessite for ultrafast and ultrastable sodium ion storage

Layered Na x MnO2 cathode suffers from structural instability and sluggish kinetics. Here the authors show a method to yield monoclinic NaMn2−y−δ(OH)2y, a new polymorph of Na-birnessite with maximum Na occupancy and enlarged interlayer spacing, enabling outstanding cyclability and rate performance....
