Summary: Through doping B3+ using a high-temperature solid-phase method, the electrochemical properties of the LiNi0.815Co0.15Al0.035O2 cathode (NCA) were significantly improved. X-ray diffraction analysis and Rietveld refinement showed that B3+ enhanced lattice ordering by minimizing Li+/Ni2+ mixing. Scanning electron microscopy observations indicated that B3+ doping changed the particle morphology. The specific discharge capacities of 1.5% B-NCA were 178.31 and 123.74 mAhg 1 at 0.2 and 5C, respectively. After 100 cycles, the specific discharge capacity was 176.29 mAhg 1 at 0.2C with a capacity retention of 98.87%. Boron doping significantly improves the structural stability of nickel-rich cathode materials by suppressing the detrimental H2 & RARR;H3 phase transition, thus improving the electrochemical performance of nickel-rich ternary lithium-ion batteries.

Summary: So far, SpiroOMeTAD has been extensively used in high-performance perovskite solar cells (PSCs) as the most studied hole transport layer (HTL) material. However, its long-term stability is limited by sensitivity to moisture and ion diffusion. In this study, we introduce a highly hydrophobic tetrathiophene polymer (PAQM-DPP) as a chemically tailored modifier for SpiroOMeTAD HTL, which forms a robust bilayer structure and significantly improves stability and tolerance to moisture. Under constant illumination conditions in a N2 atmosphere, the PSCs with the polymer/SpiroOMeTAD bilayer maintained over 92% PCE for 500 hours and exhibited higher tolerance to relative humidity compared to the SpiroOMeTAD HTL counterpart.

Summary: Surface passivation with organic iodides is crucial for high-performance perovskite solar cells (PSCs), but it often leads to stability degradation due to migration of iodine interstitial (I-i) defects. We found that untreated surface treatment can induce I-i formation and subsequent migration. Cation selection for organic iodides is important, as a strong cation-perovskite surface interaction can suppress I-i migration by increasing the migration energy barrier. Phenylpropylammonium iodide-treated PSCs achieve enhanced efficiency and stability, with a champion efficiency of 24.20% and retaining about 92% of their initial efficiency after 240 hours of continuous illumination.

Summary: Lead halide perovskite films with excellent optoelectronic properties are prepared using a residual strain regulation strategy. By adding ligand-capped CsPbI3 quantum dot solution as an antisolvent, lattice-matching CsPbI3 QDs act as heterogeneous nucleation centers and ligands regulate the crystallization kinetics, reducing residual strain. This strategy improves the film's performance by increasing grain size, decreasing defects, reducing nonradiative recombination, and improving charge transfer efficiency.

Summary: Inorganic CsPbI3 perovskite solar cells (PSCs) with high photoelectric properties face the challenge of phase instability against moisture. A curing-anti-solvent strategy is developed using an inorganic polymer (PHPS) to form a stable black-phase CsPbI3 perovskite film. The PHPS reduces moisture erosion and controls crystal growth, while a polycondensation adduct forms a shield layer to prevent phase transition. These PSCs achieve an efficiency of 19.17% and retain 90% of the initial efficiency after 1000 hours under 30% RH.

Summary: Reducing the toxicity of halide perovskites is crucial for the commercialization of perovskite photovoltaics. CsSnI3, a low-toxicity alternative, has potential, but the uncontrollable crystallization of tin-based perovskites poses challenges in obtaining high-quality thin films. In this study, high purity CsSnI3 single crystals were synthesized using a wet chemical method. By using these pre-synthesized single crystals, larger grain and defect-free CsSnI3 thin films were obtained, resulting in perovskite solar cells with a power conversion efficiency of 6.53% and excellent stability.

Summary: Ruddlesden-Popper (RP) tin-based halide perovskites have attracted attention due to their low-toxicity and low-cost processability. This study proposes a method to slow down crystallization kinetics in RP tin-based perovskites by regulating intra- and intermolecular interactions. By introducing an electron-rich heterocyclic thiophene into bulky spacers, the intermolecular interaction is decreased and intramolecular interactions are increased, leading to the stabilization of colloids and orderly crystal growth. The perovskite solar cell using this method demonstrates a two-fold improvement in power conversion efficiency compared to the control sample.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
