However, its long-cycle and rate performance are significantly constrained by the low Na⁺ electronic conductivity of NVPOF. Furthermore, the prevalent self-discharge phenomenon restricts its applicability in practical applications. In this paper, the cathode material Na₃V_1.84Fe_0.16(PO₄)₂F₃ (<em>x =</em> 0.16) was synthesized by quantitatively introducing Fe³⁺ into the V-site of NVPOF. The introduction of Fe³⁺ significantly reduced the original bandgap and the energy barrier of NVPOF, as demonstrated through density functional theory calculations (DFT). When material <em>x</em> = 0.16 is employed as the cathode material for the sodium-ion battery, the Na⁺ diffusion coefficient is significantly enhanced, exhibiting a lower activation energy of 42.93 kJ mol⁻¹. Consequently, material <em>x</em> = 0.16 exhibits excellent electrochemical performance (rate capacity: 57.32 mA h g⁻¹ @10 C, cycling capacity: the specific capacity of 101.3 mA h g⁻¹ can be stably maintained after 1000 cycles at 1 C current density). It can also achieve a full charge state in only 2.39 min at a current density of 10 C while maintaining low energy loss across various stringent self-discharge tests. In addition, the sodium storage mechanism associated with the three-phase transition of Na<em>_X</em>V_1.84Fe_0.16(PO₄)₂F₃ (<em>X =</em> 1, 2, 3) was elucidated by a series of experiments.

It is urgently needed for membrane-based CO₂ capture to develop the high-performance membrane materials with high permeability, selectivity, and stability. Herein, ultrapermeable carbon molecular sieve (CMS) membranes are fabricated by pyrolyzing a finely-engineered benzoxazole-containing copolyimide precursor for efficient CO₂ capture. The microstructure of CMS membrane has been optimized by initially engineering the precursor-chemistry and subsequently tuning the pyrolysis process. Deep insights into the structure-property relationship of CMSs are provided in detail by a combination of experimental characterization and molecular simulations. We demonstrate that the intrinsically high free volume environment of the precursor, coupled with the steric hindrance of thermostable contorted fragments, promotes the formation of loosely packed and ultramicroporous carbon structures within the resultant CMS membrane, thereby enabling efficient CO₂ discrimination via size sieving and affinity. The membrane achieves an ultrahigh CO₂ permeability, good selectivity, and excellent stability. After one month of long-term operation, the CO₂ permeability in the mixed gas is maintained at 11,800 Barrer, with a CO₂/N₂ selectivity exceeding 60.

However, in most applications, the fPSCs suffer from constant external stress, such as being kept at a convex bending state, imposing external stress on the brittle perovskite films and causing the fPSCs long-term stability problems. Overcoming these issues is vital. Herein, we propose an effective way to enhance the stability of the fPSCs under convex bending by modulating the residual stress of perovskite film for the first time. Specifically, we have carefully designed a synergistic strain engineering to toughen the perovskite films by introducing 1-butyl-3-methylimidazolium tetrafluoroborate, citric acid, and a novel cross-linker, 5-(1,2-dithiolan-3-yl) pentanoate into perovskite films simultaneously. Besides passivating the perovskite films, the multiple additives effectively convert the residual stress within the perovskite films from tensile to compressive type to alleviate the detrimental impact of bending on the flexible perovskite films. As a result, the optimal efficiencies of triple-additive modified fPSCs have achieved 22.19% (0.06 cm²) and 19.44% (1.02 cm²). More importantly, the strategy could significantly improve the stability of the perovskite films and fPSCs at a convex bending state.

Quantifying micro-cracks and voids in CAMs can reveal the degradation mechanisms of Ni-rich oxide-based cathodes during electrochemical cycling.

To overcome these challenges, strategies for optimizing the electrolyte are crucial for enhancing the stability of the zinc anode. Inspired by the role of hemoglobin in blood cells, which facilitates oxygen transport during human respiration, an innovative inorganic colloidal electrolyte has been developed: calcium silicate-ZnSO₄ (denoted as CS-ZSO). This electrolyte operates in weak acidic environment and releases calcium ions, which participate in homotopic substitution with zinc ions, while the solvation environment of hydrated zinc ions in the electrolyte is regulated. The reduced energy barrier for the transfer of zinc ions and the energy barrier for the desolvation of hydrated ions imply faster ion transfer kinetics and accelerated desolvation processes, thus favoring the mass transfer process. Furthermore, the silicate colloidal particles act as lubricants, improving the transfer of zinc ions. Together, these factors contribute to the more uniform concentration of zinc ions at the electrode/electrolyte interface, effectively inhibiting zinc dendrite formation and reducing by-product accumulation.
