“…The steady performance of Fe 3 C@PCA-2 shown in Figure d at different current densities delivered reversible capacities of 260, 187, 154, 132, 116, 104, 95, 87, 81, and 74 mA h g –1 at 100, 200, 300, 400, 500, 600, 700, 800, 900, and 1000 mA g –1 , respectively . Furthermore, it recovered to 443 mA h g –1 at 100 mA g –1 , indicating high reversibility for Fe 3 C@PCA-2 . The Fe 3 C@PCA-2 nanocomposite exhibited an excellent reversible capacity and cycling stability as an anode material for PIBs …”

Recent Advances in Heterostructured Carbon Materials as Anodes for Sodium‐Ion Batteries

“…[51] Thus, the transformation of 2D graphene into a 3D structure is a viable route to overcome this stacking issue and improve graphene properties. Nishina et al [52] fabricated a 3D graphene by in situ formation of iron hydroxide (Fe(OH) x ) nanoparticles on the surface of graphene oxide, followed by hightemperature treatment and hydrochloric acid wash. The 3D graphene, when tested in SIBs, achieved a capacity of 252 mAh g À1 at 100 mA g À1 with good rate performance.…”

Ultrahigh areal capacity and long cycling stability of sodium metal anodes boosted using a 3D-printed sodiophilic MXene/rGO microlattice aerogel

“…[6][7][8][9][10][11][12][13][14] Extensive research efforts have been devoted to addressing these issues, mainly including optimization of the electrolyte and additives, development of a stable artificial SEI, construction of threedimensional (3D) nanostructures and design of sodiophilic interfaces. [15][16][17][18][19][20][21][22][23][24] Although numerous advancements have been achieved for sodium metal anodes, a high areal capacity with a long cycle lifespan of sodium metal anodes remains a topic requiring further exploration.…”
