“…As shown in Fig. 3(b), a distinct peak located at 0.5 V can be observed during the cathodic sweep in the first cycle and it could be attributed to the conversion of the Co 3 O 4 and Li to metallic cobalt and Li 2 O 23 . The anodic peak at 1.71 V is attributed to the electrochemical reaction of the oxidization of Co 0 to Co 3 O 4 .…”

BACKGROUND Metal oxides suffer from huge volume changes and poor electrical conductivity as anode materials in lithium‐ion batteries. Many nanostructures have been designed to improve the electrochemical performance of metal oxide anodes. RESULTS In this work, Co3O4@carbon composites are prepared via hydrothermal reaction. The as‐prepared Co3O4@carbon composites displayed good lithium storage performance and excellent cycling stability. The Co3O4@carbon anode showed a high capacity of 986 mAh/g after 100 cycles at 0.2 C. CONCLUSION The superior electrochemical performance of the Co3O4@carbon anode is attributed to its unique hybrid structure, which can improve electrical conductivity and act as a buffer for the volume change during electrochemical reactions. © 2022 Society of Chemical Industry (SCI).

“…Moreover, the ex situ EIS result further illustrated that there exist a phase conversion process accompanied by the formation of SEI layer. [56] However, similar to the most investigated B-TMNs powder materials, when assembled present hollow structure NiCo 2 N material as anode for LIBs, it will unavoidable to use binder, which was against to the electrochemical performance of the electrode material. To overcome this shortcoming, our group also synthesized a self-supported NiCo 2 N electrode by electrostatic spray deposition method and systematically investigated its electrochemical properties.…”

The ever‐growing market of energy storage devices in portable electronics, electric vehicles, and smart grids has attracted extensive investigation on lithium‐ and sodium‐ion batteries in the past few years. Lithium‐ion batteries (LIBs) are currently the most commercially used energy storage devices in various occasions, while sodium‐ion batteries (SIBs) are expected to complement LIBs in large‐scale applications. To meet the rapid increase on the energy density of batteries, it is imperative to explore new electrode materials for rechargeable LIBs and SIBs. In the past few years, transition metal nitrides (TMNs) have been considered as promising anode materials for both LIBs and SIBs due to their much higher electronic conductivity and relatively lower conversion reaction potential. Moreover, TMNs are also the optimum compositing materials to enhance the performance of general anode material. In this paper, the design approach, synthesis routine, and the latest advances in the development of TMNs and TMN‐based hybrid materials served as anode for LIBs or SIBs are summarized. Also, challenges and perspectives in the future of TMNs‐related materials are also discussed.

“…The low intensity peak at 402.6 ± 0.2 eV suggests that some nitrogen atoms are in the form of oxygenated compounds: pyridine N-oxide. 49 The sulphur signal is fitted with four different chemical states. The fitting revealed that the main sulphur peak is due to either C-S-C or thiophene ( peaks at 163.70, and 164.5 eV).…”
