“…When b is equal to 1, the capacity is contributed through pseudocapacitive behavior, while b approaches 0.5, indicating that the ion storage capacity is mainly controlled by diffusion process. , As shown in Figure c, the Co 3 O 4 /rGO electrode shows b values of 0.59, 0.84, 0.79, and 0.72 for peaks 1–4, respectively, suggesting a hybrid ion storage behavior. The pseudocapacitive contribution can be quantitatively calculated according to eqs and . − i false( v false) = k 1 v + k 2 v 1 / 2 i false( v false) / v 1 / 2 = k 1 v 1 / 2 + k 2 …”

Transition metal oxide-based anode materials possess high theoretical capacity and abundant resources but are limited by severe volume variation and intrinsic low conductivity, thus leading to rapid capacity decay and poor rate performance. Herein, we develop a strategy to prepare porous hierarchical Co 3 O 4 nanopsheres by controlling the annealing process of Cogluconates, and the Co 3 O 4 nanospheres were successfully wrapped by rGO nanosheets with good dispersion through facile hydrothermal treatment. The Co 3 O 4 /rGO electrode demonstrates outstanding lithium storage properties, delivering a reversible capacity of 949.4 mA h g −1 at 500 mA g −1 after 300 cycles and 512.3 mA h g −1 at 2000 mA g −1 even after 1000 cycles. The introduction of rGO nanosheets not only greatly enhances the electron conductivity but also offers high pseudocapacitive lithium storage behavior. More importantly, the integration of porous hierarchical electrode materials with conductive matrices can be generally applied for the development of high-performance energy storage devices.

[ 78 ] conducted a three‐step procedure, starting from the hydrothermal synthesis of Co‐gallate complex as precursor followed by sulfurization and carbonization and subsequent molten infusion of sulfur, to synthesize CoS 2 /C microprisms sulfur cathode material (S@CoS 2 /C). The engineered porous architecture enables the suppressing of sulfur volume changes during cycling and thus retains the integrity of the microstructure.…”

Room‐temperature sodium–sulfur (RT Na–S) batteries have emerged as a promising candidate for next‐generation scalable energy storage systems, due to their high theoretical energy density, low cost, and natural abundance. However, the practical applications of these batteries are hindered by the notorious shuttle effect of soluble sodium polysulfides (NaPSs) and sluggish reaction kinetics, which result in fast performance loss. To address this issue, recent studies have reported impressive achievements of transition metal nanoparticles/single atoms/cluster/compounds (TM)‐based host materials with strong adsorption and catalyzation to NaPSs. These materials can significantly improve the electrochemical performance of RT Na–S batteries. In this review, the recent progress on TM‐based host materials for RT Na–S batteries, including iron (Fe)‐, cobalt (Co)‐, nickel (Ni)‐, molybdenum (Mo)‐, titanium (Ti)‐, vanadium (V)‐, manganese (Mn)‐, and other TM‐based materials are summarized. The design, fabrication, and properties of these host materials are comprehensively summarized and systematically analyzed the underlying chemical inhibition and electrocatalysis mechanism between NaPSs and TM‐based catalytic materials. At last, the challenges and prospects for designing efficient TM‐based catalytic materials for high‐performance RT Na–S batteries are discussed.
