## Description

- description: Despite lithium-oxygen batteries (LOBs) achieving energy densities
    over 500 Watt hours (Wh) kg−1 at the cell level, challenges remain in extending
    cycle life, high-rate operation, and scalability. A critical limitation lies in
    designing carbon-based positive electrodes with optimal porosity and stability.
    Previous efforts with highly porous carbon materials face issues like unoptimized
    pore structures, excessive microporosity, low stability, and non-scalable fabrication
    methods, particularly under lean-electrolyte conditions. Here, we report a scalable,
    cost-effective approach to fabricate self-standing carbon membranes via (1) hard-templated
    synthesis of mesoporous carbon with reduced microporosity, (2) slurry casting
    using the doctor-blade method, and (3) non-solvent-induced phase separation (NIPS)
    to create interconnected macropores for improved oxygen transport. LOB cells employing
    these hierarchically porous carbon membranes and lean electrolyte demonstrated
    stable cycling for over 150 cycles at 1.5 mA cm−2. Additionally, a 1-Wh-class
    multi-stacked LOB achieved long cycling stability. This report offers a breakthrough
    in scalable, high-energy-density LOB electrode development.
