Breaking Boundaries: Advancing Trisulfur Radical-Mediated Catalysis for High-Performance Lithium–Sulfur Batteries

• Trisulfur radicals (TRs) serve as mediated catalysts to mitigate shuttle effect, electrode passivation, and slow kinetics in lithium–sulfur batteries. • The formation of TRs in solid-state lapis lazuli analogs and the role of high donor number solvents in stabilizing TRs are emphasized. • Detection techniques for monitoring TRs are critical for understanding their behavior and optimizing battery design. • Homogeneous and heterogeneous catalyst strategies are summarized to enhance TR generation and catalytic reactions for practical LSB applications.
