Abstract Sodium-ion batteries stand a chance of enabling fast charging ability and long lifespan while operating at low temperature (low-T). However, sluggish kinetics aggravated dendrites present two major challenges for anodes to achieve the goal low-T. Herein, we propose an interlayer confined strategy tailoring nitrogen terminals on Ti 3 C 2 MXene (Ti -N funct ) address these issues. The introduction endows with large space charge redistribution, improved conductivity sufficient...
Abstract The practical application of hard carbon in sodium‐ion batteries is limited by insufficient reversible capacity and low initial Coulombic efficiency (ICE), which are caused the lack active sites unstable electrode/electrolyte interface. Herein, a biomass‐derived material based on tea stems proposed, exhibits an ultrahigh ICE 90.8%. This remarkable attributed to presence inorganic‐rich, thin, robust solid electrolyte interface (SEI) layer. Furthermore, demonstrates excellent cycling...

Abstract Spinel LiNi 0.5 Mn 1.5 O 4 (LNMO), high‐voltage and high‐power density, is a very promising cathode candidate. Nevertheless, its lack of cycling stability has historically been long accepted as an inherent issue. Based on the above problem, strategy initiated to directly address dissolution unstable interface structure. A beneficial solid‐phase reaction occurs at LNMO interface, transforming spinel phase into two functional phases. One layered that provides electrochemical activity...
Battery performance at subzero is restricted by sluggish interfacial kinetics. To resolve this issue, potassium-based dual-ion batteries (K-DIBs) based on the polytriphenylamine (PTPAn) cathode with anion storage chemistry and hydrogen titanate (HTO) anode K+ /solvent co-intercalation mechanism are constructed. Both PTPAn HTO do not undergo desolvation process, which can effectively accelerate kinetics subzero. As revealed theoretical calculations experimental analysis, strong binding energy...
