    Heterogeneous catalysis is often plagued by incompatibility of a catalyst’s reactivity and stability. Now, covalent organic frameworks linked by reactive, yet stable, N-heterocyclic carbene precursors are synthesized and the frameworks are subsequently used as cathodes in Li–S batteries.

    Redox flow batteries offer a readily scalable solution to grid-scale energy storage, but their application is generally limited to ambient temperatures above 0 °C. Now, a polyoxometalate-based chemistry has been developed to enable redox flow batteries to operate, and even thrive, under frigid conditions.

    Severe capacity fade in layered sodium oxide cathodes hinders their commercial feasibility in sodium batteries. Now, intrinsic lattice strain is unveiled as a new origin for their short cycle life, in addition to the common belief that phase transition or parasitic reactions are solely responsible.

    Studying the kinetics of high-energy and high-power batteries is a formidable challenge. Now, it has been shown that redox-mediated (RM) catalysis in Li–O2 and Li–S batteries can be controlled by tuning parameters such as Li-ion concentration or electrolyte solvent, revealing threshold potentials in which rate constants increase several-fold.
