[151c] The presence of a polysulfides additive prevented the dissolution of Li 2 S x , thus reducing the shuttle effect and improving the cycle performance. However, the shuttle effect caused by polysulfides dissolution is still a challenge for sulfur‐based batteries even if the metallic Li anode is replaced.…”

“…Rao and co‐workers developed a highly porous 3D tin/graphene/reduced graphene oxide (Sn/G/rGO) composite on carbon paper substrate as a binder‐free anode. [151a] An Sn/G composite was first synthesized by an electrodeposition method and then coated with rGO by drop casting to form a sandwich structure. This novel anode readily accommodated the volume expansion and facilitated the formation of a stable SEI layer on the anode surface.…”

Here, we present a lithiated molybdate‐sulfur battery with practical energy density greater than 300 Wh kg−1. Electrochemically pre‐lithiated α‐MoO3 is prepared to form lithium molybdate anode which was tested against mesoporous titania coated sulfur cathode. A pouch cell with a capacity of 5 mAh made using pre‐lithiated lithium molybdate nanowires as anode and mesoporous TiO2 (titania) coated carbon‐sulfur cathode exhibited 1.4 V operating voltage and exhibited 620 Wh kg−1 capacity in the first cycle, dropped to ∼400 Wh kg−1 in 2nd cycle and 300 Wh kg−1 at 100th cycle. Various prelithiation studies indicate that electrochemical lithiation of MoO3 nanomaterials is crucial to make Li2MoO3 material suitable as anode. In situ electrochemical lithiation of MoO3 anode is introduced as a method to fabricate lithium molybdate (Li2MoO3)‐sulfur pouch cells in one step.

Impact of the Carbon Matrix Composition on the S/C Cathode Porosity and Performance in Prototype Li–S Cells

The lithium–sulfur battery is a promising electrochemical storage solution, especially for aviation and aeronautical applications, due to its high‐gravimetric energy density (specific energy) and the abundance of sulfur. In recent years, the number of reported prototype cells and their realized energy have increased. This underlines the progress of technology readiness of the lithium–sulfur system. However, the influence of the cathode porosity as well as the porosity of the carbon material on the performance of prototype cells is still not fully understood. Consequently, in this study, the porosity of solvent‐free processed cathodes is investigated, with varying carbon matrix composition, via mercury intrusion porosimetry and synchrotron tomography. Moreover, the swelling behavior of the S/C dry‐film cathodes is investigated and mitigated. These cathodes are then electrochemically evaluated at pouch cell level with ether‐based electrolytes with varying E/S ratios. The combination of the gained findings in pouch cells enables specific energies of 425 Wh kg−1 and 558 Wh L−1 at cell level.
