  text: Capacity, rate performance, and cycle life of aprotic Li–O2 batteries critically
    depend on reversible electrodeposition of Li2O2. Current understanding states
    surface-adsorbed versus solvated LiO2 controls Li2O2 growth as surface film or
    as large particles. Herein, we show that Li2O2 forms across a wide range of electrolytes,
    carbons, and current densities as particles via solution-mediated LiO2 disproportionation,
    bringing into question the prevalence of any surface growth under practical conditions.
    We describe a unified O2 reduction mechanism, which can explain all found capacity
    relations and Li2O2 morphologies with exclusive solution discharge. Determining
    particle morphology and achievable capacities are species mobilities, true areal
    rate, and the degree of LiO2 association in solution. Capacity is conclusively
    limited by mass transport through the tortuous Li2O2 rather than electron transport
    through a passivating Li2O2 film. Provided that species mobilities and surface
    growth are high, high capacities are also achieved with weakly solvating electrolytes,
    which were previously considered prototypical for low capacity via surface growth.

  text: Cesium lead halides have intrinsically unstable crystal lattices and easily
    transform within perovskite and nonperovskite structures. In this work, we explore
    the conversion of the perovskite CsPbBr3 into Cs4PbBr6 in the presence of PbS
    at 450 °C to produce doped nanocrystal-based composites with embedded Cs4PbBr6
    nanoprecipitates. We show that PbBr2 is extracted from CsPbBr3 and diffuses into
    the PbS lattice with a consequent increase in the concentration of free charge
    carriers. This new doping strategy enables the adjustment of the density of charge
    carriers between 1019 and 1020 cm–3, and it may serve as a general strategy for
    doping other nanocrystal-based semiconductors.
