          SPEAKER: Howard Lee

          Batteries based on new chemistries that can store more energy than state-of-the-art lithium-ion devices will play an important role in enabling the energy transition to net zero carbon emission. Our previous work has shown that compact electrodes assembled from monolayered nanosheets of metallic 1T phase MoS2 are highly conductive, lyophilic, and are catalytically active. I will briefly describe the different phases of 2D MoS2 and their catalytic properties – focusing on the role of sulfur vacancies and strain. Here we report the realization of high-performance lithium-sulfur batteries using metallic 1T phase of two-dimensional molybdenum disulfide as binder-free conducting cathodes for hosting sulfur. The attributes of metallic 2D MoS2 lead to > 85% utilization of sulfur due to improved adsorption of lithium polysulfides, enhanced Li+ diffusivity, accelerated electrochemical reaction kinetics and superior electrocatalytic activity for polysulfide conversion. We have translated these properties into practical pouch cells, achieving areal capacities of 8.21 ± 0.07 mAh cm-2 and capacity retention in excess of 85% over 200 cycles. The metallic MoS2-based ampere-hour-scale (1.3 ± 0.05 Ah) pouch cells can deliver gravimetric energy density of 402 Wh kg-1 and volumetric energy density of 721 Wh L-1. These metrics compare exceptionally favourably with current state-of-the-art in Li-S batteries. Our results provide unique insights into new designs for Li-S cathodes based on electrocatalytically active and conducting two-dimensional (2D) materials.

          We believe

          each soul on this earth is a small universe

          We believe

          communication builds bridges among our small universes

          We believe

          numberless small universes go together will converge a boundless universe

          Changing the present

          Creating the future
