Abstract The practical application of room‐temperature sodium‐sulfur (RT Na−S) batteries is severely hindered by inhomogeneous sodium deposition and notorious polysulfides (NaPSs) shuttling. Herein, novel thiotellurate (Na 2 TeS 3 ) interfaces are constructed both on the cathode anode for Na−S to simultaneously address Na dendritic growth On side, a heterostructural sulfide/sodium telluride embedded in carbon matrix S/Na Te@C) rationally designed through facile carbothermal reaction, where interface will be situ chemically obtained. Such an provides abundant electron/ion diffusion channels ensures rich catalytic surfaces toward redox, which could significantly improve utilization active material alleviate shuttling cathode. inevitable formation soluble polytellurosulfides species migrate surface, finally constructing compact smooth solid‐electrolyte interphase (SEI) layer. electrochemical formed can enhance ionic transport stabilize deposition, thus realizing dendrite‐free Na‐metal plating/stripping. Benefitting from these advantages, anode‐free cell fabricated with Te@C exhibits ultrahigh initial discharge capacity 634 mAh g −1 at 0.1 C, pave new path design high‐performance cathodes RT batteries.

With extremely high specific capacity and energy density, lithium–sulfur batteries (LSBs) have attracted enormous interest as promising candidates for storage devices. However, several problems, such the shuttle effect sluggish redox kinetics, hinder successful realization of LSBs on an industrial scale. Therefore, designing efficient electrode material to inhibit improve reaction kinetics polysulfides (LiPS) is utmost significance. Herein, a bifunctional additive with excellent polysulfide adsorption superior catalytic behavior developed using phthalocyanine-tetrasulfonic acid nickel complex tetrasodium salt (Ni-PCTs) additive. Ni-PCTs provide effective trapping LiPS due their abundant sulfonic groups. Moreover, exhibit conversion presence N atoms in phthalocyanine ring well central Ni atoms. Consequently, as-assembled LSBs, 10 wt % additive, significant increase capacities, initial 1283 mA h g–1 at 0.15 mA/cm2 stable 623 after 400 cycles. The current study demonstrates promise metal phthalocyanines sulfur cathodes, opening up avenues further research development LSBs.

Metal (Li, Na, K, Al)-ion batteries and lithium-sulfur lithium-tellurium are gaining recognition for their eco-friendly characteristics, substantial energy density, sustainable attributes. However, the overall performance of rechargeable heavily depends on electrode materials. Transition metal tellurides have recently gained significant attention due to high electrical conductivity density. Cobalt telluride has received most extensive research its catalytic activity, unique magnetic properties, diverse composition crystal structure. Nevertheless, limited volume variation contribute structural deterioration rapid capacity decline. This review comprehensively summarizes recent advances in rational design synthesis modified cobalt telluride-based electrodes, encompassing defect engineering (Te vacancies, cation heterointerfaces, homogeneous interfaces) composite (derived carbon from precursors, fibers, Mxene, graphene nanosheets, etc.). Particularly, intricate evolution mechanisms conversion reaction process during cycling elucidated. Furthermore, these strategies applied other transitional tellurides, such as iron telluride, nickel zinc copper molybdenum etc., also thoroughly summarized. Additionally, application extends emerging aqueous zinc-ion batteries. Finally, potential challenges prospects discussed further propel development transition materials next-generation
