Single-crystalline layered oxides offer a promising solution to mitigate the rapid capacity decay observed in conventional polycrystalline nickel-rich oxide cathodes. However, achieving both morphological (large grain size) and structural (cation-disorder-free) control in single crystals remains challenging due to the trade-off between grain growth and phase stability, particularly at high-nickel contents. Here we report cation-disorder-free ultrahigh-nickel single-crystalline oxide cathodes with ~10-μm particle sizes, comparable to commercial secondary particles, that deliver high volumetric capacity and stable cycling. These single crystals withstand calendering and resist intra-granular cracking, achieving electrode densities of up to 77% of the theoretical crystal density. The improved stability is linked to reduced structural strain and modified glide behaviour due to the absence of cation disorder, emphasizing its critical role in chemomechanical behaviour. Additionally, gas evolution is reduced by a factor of 25, and the thermal onset temperature drops by more than 20 °C at ~4.5 V versus Li/Li+, underscoring superior safety features and energy density potential. Single-crystalline layered oxides can reduce capacity decay in nickel-rich cathodes, but controlling both the particle size and cation disorder is challenging. This work reports cation-disorder-free ~10-μm single-crystalline cathodes that deliver high volumetric capacity and cycle stability as well as improved safety.

When electricity supply exceeds demand, consumers can be paid to use electricity through negative pricing. Simulations based on national surveys indicate that such pricing could double electricity loads in many US counties. However, market policies and grids must be carefully designed to avoid destabilizing the power grid with demand surges.

The use of two-dimensional perovskite interlayers enables high efficiency in perovskite solar cells and modules but presents challenges for their long-term operational stability. Here we use a co-crystal engineering approach to improve the long-term stability of these devices. We use a neutral molecule, benzoguanamine, as a linker in low-dimensional perovskites, replacing conventional ionic molecules, and form a co-crystal. By applying this co-crystal layer onto the perovskite layer, we achieve power conversion efficiency of 23.4% in small-area solar cells, and 23.1% and 18.5% on solar modules with active areas of 9.0 cm2 and 48 cm2, respectively. The solar modules retain more than 95% and 98% of their initial efficiency after >5,000 h of 1-sun light soaking and >1,000 h of ultraviolet-ray exposure, respectively, at maximum power point conditions. They also retain more than 91% of their initial efficiency after >5,000 h of continuous thermal stress at 85 °C. Two-dimensional perovskites enable high efficiency in perovskite photovoltaics but compromise operational stability. Yaghoobi Nia et al. form two-dimensional perovskite co-crystals with neutral templating molecules, improving the stability of perovskite solar modules.
