Nature Energy, Published online: 19 August 2025; doi:10.1038/s41560-025-01834-5
Methane can be converted into other useful chemicals and fuels via photocatalytic oxidative coupling, yet producing molecules with more than two carbon atoms remains difficult. Here the authors show that highly strained Au confined within the nanopores of TiO2 can convert methane to propane with high selectivity.Inert low-dimensional interfaces for perovskite solar cells
Nature Energy, Published online: 18 August 2025; doi:10.1038/s41560-025-01818-5
A selective templating growth strategy unlocks access to a previously inaccessible class of chemically inert low-dimensional (CI LD) interfaces for the protection of the underlying three-dimensional (3D) perovskite in perovskite solar cells (PSCs). Prototype 1-cm2 3D/CI LD PSCs achieve an efficiency of over 25% and exhibit high operational and thermal stability.Unified affinity paradigm for the rational design of high-efficiency lithium metal electrolytes
Nature Energy, Published online: 13 August 2025; doi:10.1038/s41560-025-01842-5
Electrolyte design is key for high-energy lithium metal batteries, but structure–performance links are hard to predict. A framework using the normalized cation/anion–solvent affinity enables quantitative prediction of microstructure, transport and interphase, driving exceptional performance.The critical importance of stack pressure in batteries
Nature Energy, Published online: 13 August 2025; doi:10.1038/s41560-025-01820-x
Stack pressure plays a critical role in battery performance, influencing electrochemical behaviour, material integrity and system efficiency. The authors analyse existing stack pressure data and establish relationships between stack pressure and battery performance to provide insights for improving battery design and efficiency.Intralattice-bonded phase-engineered ultrahigh-Ni single-crystalline cathodes suppress strain evolution
Nature Energy, Published online: 12 August 2025; doi:10.1038/s41560-025-01827-4
Single-crystal Ni-rich cathodes improve mechanical stability but suffer from long diffusion paths and structural strain. This study presents an intralattice-bonded design that achieves near-zero degradation and exceptional cycling performance.Enhancing hole-conductor-free, printable mesoscopic perovskite solar cells through post-fabrication treatment via electrophilic reaction
Nature Energy, Published online: 08 August 2025; doi:10.1038/s41560-025-01823-8
Printable mesoscopic perovskite solar cells are a promising device design, yet their efficiency is limited by charge collection. Ma et al. use hexamethylene diisocyanate to eliminate unreacted organic cations at grain boundaries, enhancing hole collection.Exceeding the kilowatt threshold
Nature Energy, Published online: 07 August 2025; doi:10.1038/s41560-025-01835-4
Elastocaloric cooling is a promising alternative to conventional vapour-compression systems, but greater cooling power is needed for practical use. Now, a series of design optimizations have produced an elastocaloric system delivering kilowatt-scale cooling power, a milestone towards practical solid-state cooling.Impurity-tolerant catalysis
Nature Energy, Published online: 06 August 2025; doi:10.1038/s41560-025-01832-7
Liquid organic hydrogen carriers (LOHCs) can store and transport hydrogen using existing fuel infrastructure, but typically require fossil-derived storage compounds, precious-metal catalysts and pure hydrogen feeds. Now, a diol/lactone LOHC system in combination with an inverse Al2O3/Cu catalyst addresses all three issues.Exceptional layered cathode stability at 4.8 V via supersaturated high-valence cation design
Nature Energy, Published online: 06 August 2025; doi:10.1038/s41560-025-01831-8
Ni-rich layered cathodes promise higher energy density at high voltages, but suffer from poor cycling stability. This study improves stability by introducing a supersaturated high-valence cation surface layer that stabilizes the structure and suppresses side reactions for durable cycling at 4.8 V.Passivation by design
Nature Energy, Published online: 01 August 2025; doi:10.1038/s41560-025-01826-5
The chemistry at the lithium metal–electrolyte interface determines the cycling stability of lithium-metal electrodes but is challenging to control. A new study demonstrates that polymer coatings can both passivate the reactive lithium metal and selectively modulate interfacial electrolyte species, enabling stable cycling of high-energy-density pouch cells.Solar and batteries are affordable options for US households

A majority of US households can reduce energy costs and access affordable backup power during outages through rooftop solar and battery storage. Policymakers need to evaluate and adopt measures to ensure high-outage-risk and energy-burdened communities have equitable access to these adaptation solutions as climate impacts intensify outages.Solar and battery can reduce energy costs and provide affordable outage backup for US households
Nature Energy, Published online: 01 August 2025; doi:10.1038/s41560-025-01821-w
Rooftop solar and battery storage can reduce energy costs and provide affordable back-up power for over 60% of US households, but benefits often bypass the high outage risk and disadvantaged communities most in need.Selective templating growth of chemically inert low-dimensional interfaces for perovskite solar cells

The effective surface area of a solid oxide cell has a direct impact on its performance but maximizing it within a limited volume or mass remains a major challenge. Now, research reports a three-dimensional-structured ‘gyroidal’ solid oxide cell design that exhibits a significantly higher surface area and promising performance metrics per unit volume and mass.
