Although vanadium oxides with different compositions demonstrate promising potential as the cathodes of AZIBs, the narrow interlayer spacing, inferior electronic conductivity, and high dissolution in electrolyte seriously restrict their practical applications. Here we design an ingenious bimetallic-ions (Mg2+ and Al3+) co-intercalation strategy to boost the AZIBs performances of V6O131.31H2O (VOH). The bimetallic-ions intercalation expands the interlayer spacing, increases the electronic conductivity, and more importantly stabilizes the vanadium-oxygen bond in VOH, which promotes the ion/electron transport kinetics and restrains the vanadium oxides dissolution. As expected, MgAl-VOH cathodes deliver ultrahigh specific capacities of 524.9 and 275.6 mAh g−1 at the current densities of 0.1 and 5 A g−1, respectively, comparable to the highest value in vanadium oxides. The underlying zinc-ion storage mechanism is unambiguously clarified with the aid of density function theory calculations and in-situ structure characterizations.

In this study, we explore the effects of five distinct ammonia concentrations (0.2 mol/L, 0.3 mol/L, 0.4 mol/L, gradually increasing from 0 to 0.4 mol/L, and decreasing from 0.4 to 0.12 mol/L) on the microstructure of the Ni0.95Al0.05(OH)2.05 precursor throughout the precipitation process. The results reveal that ammonia concentration significantly influences both nucleation and crystal growth rates, with higher ammonia levels reducing nucleation rates and leading to more uniform agglomerates. Additionally, ammonia concentration affects the thickness-to-length ratio of the precursor's primary particles, which in turn influences the morphology of the LiNi0.95Al0.05O2 cathode materials during lithiation. Importantly, the study demonstrates that the electrochemical properties of LiNi0.95Al0.05O2 are more closely related to the shape of the primary particles than to the secondary particles, highlighting the critical importance of microstructural control in the design of next-generation Li-ion batteries.

However, achieving both a large d33 and a high mechanical quality factor (Qm) is generally considered challenging due to the inherent trade-off between these properties. This challenge is particularly pronounced in the development of lead-free piezoelectric materials. In this work, we present a novel approach that integrates heterogeneous diffusion with remnant hardening in potassium sodium niobate (KNN)-based composites. This method results in a more than threefold increase in the Qm, jumping from 56 to 205 while a high d33 value (d33 = 370 pC/N) is maintained, significantly outperforming previous reports. Structural characterization and phase-field simulations revealed that the synergistic effects of local structural heterogeneity and local stress fields achieve excellent electromechanical compatibility. This dual modulation effectively overcomes the longstanding conflict between piezoelectric properties and mechanical losses.

However, rapid crystallization leads to poor film quality and the formation of defects, resulting in severe non-radiative recombination that hinders the improvement of device performance. In this work, an organic small molecule, dicyandiamide (DCDA), with multifunctional groups was incorporated into the perovskite precursor solution to concurrently regulate crystallization and manage defects in the perovskite in the mesoporous scaffold, and high performance MPSCs were obtained. Due to the robust interactions of the –C<img alt=\"[double bond, length as m-dash]\" border=\"0\" src=\"https://www.rsc.org/images/entities/char_e001.gif\"/>N and –CN groups in DCDA with un-coordinated Pb2+, and/or FA+/MA+ via hydrogen bonding, coupled with the –NH2 groups of DCDA forming hydrogen bonding or electrostatic interactions with halide anions to inhibit ion migration, the defects were passivated. The introduction of DCDA effectively retarded nucleation and grain growth, and significantly reduced the film formation rate. Thus, perovskite films with larger grain sizes, preferred orientation, and lower trap state density were obtained, thereby greatly suppressing non-radiative recombination. As a result, the average power conversion efficiency (PCE) of MPSCs treated with DCDA was improved from 17.15 ± 0.48% to 18.75 ± 0.42%, and a champion PCE of 19.12% was obtained. Meanwhile, the PCE of unpackaged MPSC devices still remained at 94.00% of the initial efficiency when stored in an air environment after 103 days, demonstrating excellent stability.
