The pore size in the synthesized cathodes plays a crucial role in inhibiting the shuttle effect, which, as mentioned previously, is a significant challenge this work intends to overcome. Large pores can allow for the diffusion and loss of polysulfide species, facilitating their migration and subsequent reactions with the lithium anode. By reducing the pore size, it is possible to confine the polysulfide intermediates within the cathode structure, hindering their diffusion and migration. This confinement can effectively inhibit the shuttle effect, leading to improved cycling stability and higher energy efficiency.
