  • Chlorine electrosynthesis from seawater is limited by poor selectivity and stability under industrial-scale conditions. Here atomic-step-enriched ultrafine high-entropy alloy nanowires enable highly efficient chlorine evolution at 10 kA m−2 for over 5,500 h through dynamic Pt–O active sites, reducing electricity consumption and feedstock costs for next-generation chlor-alkali processes.

  • Electrolyte|electrode instability largely limits battery lifespan of lithium-carbon dioxide batteries. Here, authors design a decoupled electrolyte system that enables long-term cycling and low overpotential in Li-CO2 batteries by regulating solvation structures near the positive electrode during dynamic cycling.

  • Aqueous zinc batteries possess advantages in safety, cost and environmental friendliness. To address side reaction, limited cycle life and other challenges, the authors formulate a dual-salt electrolyte that decouples the interfacial electrolyte from the bulk, enabling suppressed hydrogen evolution, fast zinc transport and resilience against low temperature.

  • Sluggish kinetics of the CO2 reactions lead to the accumulation of Li2CO3 residuals, which hinders the cycling stability of Li-CO2 batteries. Here, the authors reveal the catalytic role of in-situ formed C-N species in enhancing the reversibility of Li2CO3 and cycle life of Li-CO2 batteries.

  • Aqueous zinc metal batteries utilized in wearable and implanted devices require good biosecurity, long lifespan, and high flexibility. Here, the authors proposed a biocompatible hyaluronic acid-based gel electrolyte to improve the reversibility of zinc anodes and prolong the cycle life of batteries.

  • The electrochemical performance of aqueous zinc ion batteries is limited by water activity. Here, the authors propose a hybrid electrolyte that incorporate strongly polar molecules to strengthen the water O–H bonds, thus reduce water activity and improve the electrochemical performance of the batteries.

  • Metal–CO2 batteries offer the dual benefits of energy storage and carbon utilization, but their commercial viability is limited by drawbacks in performance, cost and safety. This Review discusses barriers to the development and commercialization of aqueous and non-aqueous metal–CO2 batteries and how to overcome them.
