Application of Bimetallic-based Catalyst Materials in Lithium-sulfur Batteries. (English)

Lithium-sulfur batteries are top contenders to replace conventional lithium-ion batteries due to their ultra-high theoretical energy density. However, the batteries were plagued by poor electrical conductivity, severe shuttle effect, and slow reaction kinetics, which would ultimately result in rapid cycle decay and poor stability. Bimetallic-based catalysts could synergize interactions between metals or metal compounds, optimize electronic structure, with good adsorption and catalytic conversion of polysulfides, improve cycle stability and rate performance of lithium-sulfur batteries. The strategies of bimetallic-based catalysts in improving the effectiveness and stability of lithium-sulfur batteries were summarized. Additionally, the prospects and challenges of the application of bimetallic-based catalysts in lithium-sulfur batteries were discussed. [ABSTRACT FROM AUTHOR]
