Summary: This study designs a porous carbon-based sulfur electrode for high-energy Li-S batteries. By impregnating the porous carbon with a high concentration of sulfur and reducing the content of conductive agent and binder, crack formation during electrode drying can be inhibited. Two distinct electrically conducting networks are utilized to reduce battery polarization and achieve a capacity of 690 mAh g(-1) even after 100 cycles. Pouch cells are prepared to evaluate the practical performance, resulting in a capacity of 741 mAh and a cathode energy density of 1001 Wh kg(-1). These findings are expected to guide the further development of high-energy-density cathode materials for Li-S batteries.

Summary: This study investigates the relationship between polysulfide solvation structure and electrode kinetics in lithium-sulfur batteries and proposes methods to improve their cycling performance. The solvation structure derived from strong solvating power electrolyte leads to rapid anode kinetics, while that derived from weak solvating power electrolyte causes slow cathode kinetics. A solvation structure with medium solvating power balances both cathode and anode kinetics, enhancing the cycling performance of lithium-sulfur batteries.

Summary: Sodium-ion batteries (SIBs), a promising alternative to lithium-ion batteries (LIBs), are essential for future electric vehicles and energy storage systems. While the recycling of spent SIBs and LIBs face similar environmental and economic challenges, the recycling of SIBs is more economically demanding. Proactive strategies must be implemented during the early commercialization stage to ensure easy recycling, low operation costs, and optimal efficiency of SIBs. This Perspective article provides an overview of the components of SIBs, discusses recycling strategies, and highlights the challenges and future prospects of SIB recycling.

Summary: The passivation of carbon in lithium-sulfur batteries under lean electrolyte conditions does not severely limit performance. Introducing higher surface area carbon in the sulfur electrode formulation is unnecessary to prevent passivation. The focus of lithium-sulfur development should be directed towards addressing other issues such as undesirable reactions at the lithium electrode and achieving robust sulfur electrode structures.
