Electrifying membrane synthesis

Membranes based on metal–organic frameworks (MOFs) could offer an energy-efficient way of separating chemical mixtures, but it can be difficult to prepare the high-quality MOF films that are needed. Zhou et al. use an electrochemical method to fabricate high-performance defect-free MOF membranes (cross section pictured) for the separation of hydrocarbons.

Comment & Opinion

  • The recent ruling in a Dutch court that Shell must curb its CO2 emissions is the latest in a series of legal moves bringing human rights concerns to bear on energy activities. This trend will have profound consequences for energy developments and for meeting climate goals.

  • Adoption of distributed energy resources such as wind and solar can exacerbate energy inequality. A new study shows that inequality in opportunity to adopt renewable energy resources may already be baked into the grid infrastructure design.

  • Electrolyte materials that consist of metals with organic ligands represent a promising direction for flow battery research. Now, an iron complex with the combination of bipyridine and cyanide ligands is demonstrated to have improved voltage and solubility over the commonly used ferrocyanide couple.

  • A growing body of research has sought to provide a better understanding of the determinants of energy poverty and how best to assist vulnerable groups that are at greatest risk of being energy poor. A new study examines how policy reform away from fixed and age-based support helps address energy poverty in Australia.

  • Mechanical reliability of perovskite solar cells is an important factor in ensuring their operational stability, yet it remains a critical challenge. Researchers have now demonstrated that interfacial self-assembled monolayers increase adhesion toughness between the perovskite and charge-transport layers, enhancing the device stability.

  • The challenge of how to handle large volumes of silicon photovoltaic (PV) panels at the end of their 30-year lifetime is emerging. Now, a new study reveals that the efficacy of recycling and reuse interventions is underestimated if social factors such as the attitude of PV owners and the influence of peers are not considered.

  • Metal–organic framework (MOF) membranes could lower the energy burden of molecular separations, but are impeded by challenges in fabricating defect-free MOF layers. Now, researchers design an electrochemical approach for growing high-performance MOF membranes on industrially relevant substrates.

  • Silicon-containing batteries are increasingly becoming a reality in the mass market, but their calendar aging behaviours have received comparatively little attention. Researchers from the Silicon Consortium Project discuss the issues surrounding the calendar lifetime of silicon anodes for lithium-ion batteries.

Tales of Invention

  • Almost 30 years since the inception of lithium-ion batteries, lithium–nickel–manganese–cobalt oxides are becoming the favoured cathode type in automobile batteries. Their success lies primarily with their superior energy density relative to lithium–cobalt oxide, lithium–manganese oxide and lithium–iron phosphate electrodes.
