Summary: All-solid-state Li-S batteries assembled with inorganic solid electrolyte have high safety and theoretical energy density, but the interfaces among components in composite cathodes have been a key factor affecting performance. In-situ chemical reactions such as thermal reduction and in-situ growth can be employed to improve interface performance by constructing conductive and ionic channels on the surface of Li2S.

Summary: Lithium-sulfur (Li-S) batteries have been intensively investigated as a post-Li-ion technology, but their energy density and cycling performance are still not satisfactory for commercial development. The gap between laboratory research and industrial application is mainly due to the different requirements of sulfur cathodes and electrolytes in practical batteries. The quasi-solid-state reaction mechanism holds promise for achieving high-capacity and cycle-stable sulfur cathodes.

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: Cation migration, especially of transition metals (TMs), in layered cathodes of sodium-ion batteries (SIBs) has been a significant issue, resulting in electrochemical degradation. By investigating the migration mechanism in a typical layered cathode material NaCrO2, it is found that the migration originates from random desodiation and subsequent Na-free layer formation at high charge potential. To address this issue, a Ru/Ti co-doping strategy is developed, where active Ru is selectively desodiated to suppress Na-free layer formation, while inactive Ti serves as a pillar to avoid complete desodiation in Ru-contained TM layers, leading to enhanced electrochemical performance.

Summary: To stabilize the zinc anode in zinc metal batteries, researchers have developed a controlled electrolytic method using a high dipole moment solvent dimethyl methylphosphonate (DMMP) to create a monolithic solid electrolyte interphase (SEI). This DMMP-based electrolyte generates a homogeneous and robust phosphate SEI (Zn-3(PO4)(2) and ZnP2O6). With the protection provided by this in situ monolithic SEI, the zinc electrode exhibits long-term cycling performance and high Coulombic efficiency in both zinc|zinc and zinc|copper cells. The use of a DMMP-H2O hybrid electrolyte in a full V2O5|zinc battery also results in high capacity retention following a large number of cycles.

Summary: In this study, a cobalt-based composite with a heterostructure was designed as a highly efficient electrocatalytic nitric oxide reduction (eNORR) catalyst. By integrating boron to modulate the electronic structure, the catalyst showed a significant NH3 yield and outstanding power density in a Zn-NO battery. The excellent electrochemical performance of the catalyst was attributed to the enrichment of NO by cobalt and boron dual-site adsorption and fast charge-transfer kinetics.

Summary: Organic small-molecule compounds have shown promise as cathode materials for high-performance lithium-ion batteries due to their high theoretical capacity, efficient utilization of active sites, low cost, and sustainability. However, challenges such as dissolution and poor electronic conductivity hinder their practical application. In this study, a new insoluble organic small molecule, FCPD, was synthesized by grafting ferrocene onto PPD. The FCPD cathode exhibited a large capacity, long lifespan, high-rate capability, and wide voltage window, thanks to its bipolar feature, aromatic, and mesoporous structure.
