Popis: The specific capacity of P2-type sodium-ion battery cathode is limited because full extraction of Na ions leads to structural degradation. Here authors report pillar-beam structured material to overcome this issue by using K pillar ions to uphold the transition metal layers upon extraction of Na ions.
