Lithium-ion batteries exhibit high theoretical gravimetric energy density but present a series of challenges due to the open cell architecture. Now, Zhou and co-workers confine the reversible Li2O/Li2O2 interconversion into a sealed cell by pre-embedding Li2O nanoparticles into an iridium–graphene catalytic host.
