The Cover Feature shows a multiphase nanocomposite with stable porous structure for lithium‐ion‐battery cathodes. The nanocomposites are prepared by the colloid chemical method to obtain a porous structure and using cetyltrimethylammonium bromide as dispersant and carbon source. The unique multiphase porous structure is composed of monoclinic Li 3 V 2 (PO 4 ) 3 , rhombohedral Li 3 V 2 (PO 4 ) 3 and some rhombohedral Na 3 V 2 (PO 4 ) 3 . The porous structure and isomeric phase structure ensure fast electron transmission and Li + migration for ultrahigh specific discharge capacity and excellent cycling stability at a high current rate.
