"Long-lasting, reinforced electrical networking in a high-loading Li2S " by Hun Kim, Kyeong Jun Min et al.
Realizing a lithium sulfide (Li2S) cathode with both high energy density and a long lifespan requires an innovative cathode design that maximizes electrochemical performance and resists electrode deterioration. Herein, a high-loading Li2S-based cathode with micrometric Li2S particles composed of two-dimensional graphene (Gr) and one-dimensional carbon nanotubes (CNTs) in a compact geometry is developed, and the role of CNTs in stable cycling of high-capacity Li–S batteries is emphasized. In a dimensionally combined carbon matrix, CNTs embedded within the Gr sheets create robust and sustainab...
