A Conjugated Porous Polymer Complexed with a Single-Atom Cobalt Catalyst as An Electrocatalytic Sulfur Host for Enhancing Cathode Reaction Kinetics

Xueying Fan et al.

Summary: CMPs with single-atom Co catalysts (Co-CMP) show great potential for use in Li-S batteries due to their unique structures and tunable functionality. The Co-CMP, synthesized with a dibromo salcyen Co complex and thris(ethynylthiophene)triazine, exhibits outstanding performance in terms of specific capacity, rate capability, and cycling stability. Density functional theory calculations and X-ray absorption near-edge structure spectroscopy measurements demonstrate that the single-atom Co catalyst in Co-CMP lowers cathode reaction energies by interacting with polysulfide anions and Li cations. Additionally, the modular methodology used for synthesizing Co-CMP allows for the creation of new CMPs with predictable structures and functions for broader catalytic applications.
