A layer‐by‐layer cathode is developed for high‐areal‐capacity Li–S batteries via a facile approach. Benefitting from the unique structure and favorable adsorption properties of the carbon layers, the fabricated cathodes display high capacity with superior rate and cycling performance. An areal capacity of as high as 11.3 mA h cm −2 is achieved with a six‐sulfur‐layer cathode.
