Empowering magnesium

Nature Energy, Published online: 30 November 2020; doi:10.1038/s41560-020-00744-yMg-ion diffusion in cathodes and dissociation in electrolyte complexes are sluggish processes that hinder the development of Mg batteries. Now, a new design of both the cathode and the electrolyte drastically improves the kinetics of these processes, leading to a high-power...

Selective CO₂ electrocatalysis at the pseudocapacitive nanoparticle/ordered-ligand interlayer

Nature Energy, Published online: 30 November 2020; doi:10.1038/s41560-020-00730-4The complex, multi-component environments found in enzymes induce high catalytic specificity, but are difficult to achieve in synthetic catalysts. Now, researchers report a catalyst comprising a dynamic, ordered layer of ligands above a nanoparticle surface that creates...

Time to rethink energy research

Nature Energy, Published online: 30 November 2020; doi:10.1038/s41560-020-00739-9Energy research works with units and concepts forged in an age of fossil fuel, leading to problem formulations that reinforce current societal practices and patterns of consumption. Achieving low-carbon energy goals depends on shifting demand to match supply and reconceptualizing...

Pocket the difference

Nature Energy, Published online: 30 November 2020; doi:10.1038/s41560-020-00743-zElectrochemical reduction of CO2 is a route to synthesize carbon-based products using renewable energy, but achieving high selectivity to specific molecules remains demanding. Inspired by enzymes, a nanoparticle–ligand assembly is now reported that has a floating interlayer,...

High-power Mg batteries enabled by heterogeneous enolization redox chemistry and weakly coordinating electrolytes

Nature Energy, Published online: 30 November 2020; doi:10.1038/s41560-020-00734-0Owing to sluggish Mg-ion dissociation and diffusion, Mg-based batteries have low power densities. Here the authors carry out rational designs for both the cathode and the electrolyte to enable ultrafast kinetics of a Mg metal battery.
