P3-Na0.9Fe0.5Mn0.5O2 is reported as a new P-type cathode material for Na-ion batteries. The P3 structure can accommodate 0.9 mole of Na-ions leading to a high discharge capacity of 155 mA h g-1 and does not require sacrificial salts for full-cell operation. Operando X-ray diffraction and ex situ X-ray absorption studies are also reported.
据报道，P3-Na0.9Fe0.5Mn0.5O2是一种新型的钠离子电池P型正极材料。P3结构能够容纳0.9摩尔的钠离子，从而实现155 mA h g-1的高放电容量，并且在全电池运行中不需要牺牲盐。还报道了原位X射线衍射和非原位X射线吸收研究。
