  • The development of fast-charging and high-capacity negative electrodes is critical for advanced lithium-ion batteries. Here, authors use a vacancy engineering strategy to develop a layered Prussian blue analogue with competitive rate capability, delivering a specific capacity of 510 mAh g−1 at a specific current of 8 A g−1.

  • Sodium co-intercalation in graphite negative electrodes delivers high-rate kinetics, and yet its implementation is plagued by notorious reaction potential. Here, the authors develop a flexible electrolyte design strategy based on synergistically competitive coordination that tailors the co-intercalation potential to 0.4 V in dilute ether systems, providing screening guidance for more potential regulation electrolytes.

  • Lithium–oxygen batteries allow oxygen to be reduced at the battery’s cathode when a current is drawn; in present-day batteries, this results in formation of Li2O2, but it is now shown that another high energy density material, namely LiO2, with better electronic conduction can be used instead as the discharge product, if the electrode is decorated with iridium nanoparticles.
