Abstract The sodium hexafluorophosphate (NaPF 6 )/carbonate solution is considered as the benchmark electrolyte for sodium‐ion batteries (SIBs). However, this NaPF undergoes hydrolysis and produces acidic compounds, which deteriorate quality, corrode electrodes, jeopardize electrode interphases, eventually degrade battery performance. Herein, we introduce tris(trimethylsilyl) phosphate (TMSP) a multifunctional additive to carbonate electrolyte. We found that 10% TMSP could effectively remove H 2 O molecules inhibit hydrolysis, thus improving stability against moisture during long‐term storage. Furthermore, unique structure of promotes formation thinner, more uniform, inorganic‐rich interphases on Na 3 V (PO 4 ) (NVP) cathode hard carbon (HC) anode. Consequently, NVP cathode, HC anode, full cells demonstrate excellent cycling This work suggests tailoring formulation can provide multiple benefits boosting SIB performances, such stabilizing regulating electrolyte/electrode interphase, thereby promoting in batteries.

In the domain of large-scale electrode production using ball milling techniques, achieving robust cycling stability and superior electrochemical performance in dual-functional anodes for lithium-ion batteries (LIBs) sodium-ion (SIBs) remains a formidable challenge. To tackle these objectives, we have devised distinctive hybrid anode nanocomposite characterized by its complex multiphase structure. This composite integrates innovative binary Bi/FeS nanomaterials onto exfoliated graphite nanosheets (Bi/FeS-G) via straightforward ball-milling process. Our comprehensive experimental theoretical analyses indicate that synergistic interactions between layered structure, along with Li2S Na2S discharge products, significantly enhance Li-ion Na-ion diffusion rate hierarchical architecture. storage testing, novel Bi/FeS-G material outperformed counterpart, demonstrating reversible capacity 664.1 mAh g–1 536.4 at 1.0 A 2.0 over 400 cycles, delivering capacities 409.4 g–1, 358.6 298.5 after 200 cycles 0.5 1 2 respectively, storage.

Due to its high theoretical capacity, cobalt oxide (Co3O4) has attracted attention sodium-ion battery (SIB) anodes. However, low conductivity and poor rate performance have limited practical application. This work proposes a co-precipitation doping strategy synthesize iron-doped Co3O4 nanoparticles (FexCo3-xO4 NPs). Both experimental results confirm that iron (Fe) at octahedral sites within spinel structures is critical factor in enhancing performance. The decreased bandgap enlarged ion transport spacing originate Fe doping. effectively facilitates the electron Na-ion (Na+) during discharge/charge processes, delivering an impressive capability of 402.9 mAh g-¹ 3 A g-¹.
