“…Recently, transition-metal sulfides (TMSs) have been widely used as anode materials in LIBs and SIBs owing to their excellent electronic conductivity, high theoretical capacity, and abundant redox chemical properties. [8,13,[15][16][17][18] Among them, Co and S can be combined to form various forms of compounds with different valence states such as CoS, [19][20][21] CoS 2 , [22][23][24] Co 3 S 4 , [13,25,26] Co 9 S 8 , [27][28][29] and others, which endows them as potential anode materials with high theoretical specific capacity and superior thermal stability. However, the issues of rapid capacity decay, poor reaction kinetics, and severe polarization owing to volume changes during electrochemical reactions are still huge challenges for cobalt sulfides in practical applications.…”

Cobalt sulfides have been popularly used in energy storage because of their high theoretical capacity and abundant redox reactions. However, poor reaction kinetics, rapid capacity decay, and severe polarization owing to volume changes during electrochemical reaction are still huge challenges for cobalt sulfides in practical applications. Herein, cobalt sulfide yolk–shell spheres were synthesized by phosphorus doping (P‐CoS) to stabilize the structure of cobalt sulfides and improve their electronic/ion conductivity. Kinetic tests and density functional theory calculations confirm that the introduction of phosphorus into cobalt sulfides greatly reduces the diffusion barrier of Li+ in the intrinsic structure, thereby improving the reaction kinetics of electrode materials during the Li+ insertion/extraction process. In consequence, the P‐CoS electrode delivers a high lithium storage capacity (781 mAh g−1 after 100 cycles at 0.2 A g−1), excellent rate capability (489 mAh g−1 at 10 A g−1), and outstanding cycling stability (no significant capacity decay over 4000 cycles at 5 A g−1). Especially for sodium‐ion battery application, the P‐CoS electrode expresses a striking capacity of approximately 260 mAh g−1 at 2 A g−1 after 900 cycles.

Heterostructure engineering of electrode materials, which is expected to accelerate the ion/electron transport rates driven by a built-in internal electric field at the heterointerface, offers unprecedented promise in improving their cycling stability and rate performance. Herein, carbon nanotubes with Co 9 S 8 /ZnS heterostructures embedded in a N-doped carbon framework (Co 9 S 8 /ZnS@NC) have been rationally designed via an in-situ vapor chemical transformation strategy with the aid of thiophene, which not only acted as carbon source for the growth of carbon nanotubes but also as sulfur source for the sulfurization of metal Zn and Co. Density functional theory (DFT) calculation shows an about 3.24 eV electrostatic potential difference between ZnS and Co 9 S 8 , which results in a strong electrostatic field across the interface that makes electrons transfer from Co 9 S 8 to the ZnS side. As expected, a stable cycling performance with reversible capacity of 411.2 mAh g À 1 at 1000 mA g À 1 after 300 cycles, excellent rate capability (324 mAh g À 1 at 2000 A g À 1 ) and a high percentage of pseudocapacitance contribution (87.5% at 2.2 mv/s) for lithium-ion batteries (LIBs) are achieved. This work provides a possible strategy for designing multicomponent heterostructural materials for application in energy storage and conversion fields.[a] Prof.

Sodium-ion batteries (SIBs) were investigated as recently as in the seventies. However, they have been overshadowed for decades, due to the success of lithium-ion batteries that demonstrated higher energy densities and longer cycle lives. Since then, the witness a re-emergence of the SIBs and renewed interest evidenced by an exponential increase of the publications devoted to them (about 9000 publications in 2019, more than 6000 in the first six months this year). This huge effort in research has led and is leading to an important and constant progress in the performance of the SIBs, which have conquered an industrial market and are now commercialized. This progress concerns all the elements of the batteries. We have already recently reviewed the salts and electrolytes, including solid electrolytes to build all-solid-state SIBs. The present review is then devoted to the electrode materials. For anodes, they include carbons, metal chalcogenide-based materials, intercalation-based and conversion reaction compounds (transition metal oxides and sulfides), intermetallic compounds serving as functional alloying elements. For cathodes, layered oxide materials, polyionic compounds, sulfates, pyrophosphates and Prussian blue analogs are reviewed. The electrode structuring is also discussed, as it impacts, importantly, the electrochemical performance. Attention is focused on the progress made in the last five years to report the state-of-the-art in the performance of the SIBs and justify the efforts of research.
