Abstract Nowadays, sodium‐ion batteries are considered the most promising large‐scale energy storage systems (EESs) due to low cost and wide distribution of sodium sources as well similar working principle lithium‐ion (LIBs). Therefore, screening suitable materials with high abundance, cost, excellent reliability modified different strategies based on them is key point for development (SIBs). In addition, ideal anodes elements also greatly influence SIB systems, determining application. Herein, recent advances in carbon, iron, manganese, phosphorus‐based various types, such hard iron oxides, manganese red phosphorus, highlighted. The mechanisms structure‐function properties these four types summarized analyzed detail. Considering commercial profits that EESs can bring their suitability mass electrode manufacturing, participation high‐abundance low‐cost Fe, Mn, C, P convincing encouraging.

Hollow spindle-like porous nitrogen-doped carbon nanofibers (HS-PNCNFs) were synthesized and chosen as cathode materials for flexible zinc-ion capacitors (FZICs). The synthesis was achieved through a combination of electrospinning heat treatment techniques, incorporating poly(tetrafluoroethylene) nanoparticles (PTFE NPs) sacrificial templates. This approach led to the creation an open hollow structure within fibers, significantly including enhancing their high specific surface area (SSA) defect level. When utilized material in aqueous (AZICs), HS-PNCNFs exhibited impressive performance, capacity 105 mAh g–1 at 0.2 A g–1, excellent rate performance retaining 60% 10 remarkable cycling stability maintaining 89.4% after 25,000 cycles. Additionally, FZICs, HS-PNCNF satisfactory energy density, even 150 folding/unfolding work not only demonstrates controllable fabrication method hierarchical with rich defects but also highlights vast potential storage devices. successful application AZICs FZICs suggests broad applicability various applications demanding flexibility.
