“…Figure 4a shows the XPS survey spectrum of the MoSe 2 /MoO 2 composite. The Mo 3d spectrum (Figure 4b) shows that the peaks at 231.7 eV for Mo 3d 3/2 and 227.9 eV for Mo 3d 5/2 are assigned to the Mo-Se bond in the MoSe 2 [31]. The other two peaks at 232.2 and 228.1 eV are attributed to the Mo 3d 3/2 and Mo 3d 5/2 of Mo 4+ in the MoO 2 , respectively [32].…”

A simple method is developed for the preparation of MoSe2/MoO2 composite with a flower-like structure for high-performance lithium-ion batteries (LIBs). MoSe2 could lead to fast and facile movement of Li+ due to its larger interlayer spacing. Meanwhile, MoO2 could protect the lamellar structure of MoSe2 from being destroyed in the charging/discharging processes to maintain the required active surface to electrolytes. In addition, the flower-like structure of the composite could effectively alleviate the volume expansion during charging/discharging. As LIBs are anode material, MoSe2/MoO2 composite demonstrates an excellent specific discharge capacity of 1042 mAh g−1 after 100 cycles at 0.1 A g−1, which is attributed to the synergistic effects of MoSe2 and MoO2 in the composite.

“…In the case of 2D materials, the weak bonds between their constituent sheets and the ease of intercalation of alkali ions between their layers are two of the foremost properties which make them desirable as energy storage materials [ 98 ]. The bulk counterparts of these layered materials suffer from significant volume changes upon interacting with alkali metal ions in addition to low average working voltages.…”

Beyond Graphene Anode Materials for Emerging Metal Ion Batteries and Supercapacitors

Intensive research effort is currently focused on the development of efficient, reliable, and environmentally safe electrochemical energy storage systems due to the ever-increasing global energy storage demand. Li ion battery systems have been used as the primary energy storage device over the last three decades. However, low abundance and uneven distribution of lithium and cobalt in the earth crust and the associated cost of these materials, have resulted in a concerted effort to develop beyond lithium electrochemical storage systems. In the case of non-Li ion rechargeable systems, the development of electrode materials is a significant challenge, considering the larger ionic size of the metal-ions and slower kinetics. Two-dimensional (2D) materials, such as graphene, transition metal dichalcogenides, MXenes and phosphorene, have garnered significant attention recently due to their multi-faceted advantageous properties: large surface areas, high electrical and thermal conductivity, mechanical strength, etc. Consequently, the study of 2D materials as negative electrodes is of notable importance as emerging non-Li battery systems continue to generate increasing attention. Among these interesting materials, graphene has already been extensively studied and reviewed, hence this report focuses on 2D materials beyond graphene for emerging non-Li systems. We provide a comparative analysis of 2D material chemistry, structure, and performance parameters as anode materials in rechargeable batteries and supercapacitors.

Cobalt sulfide and molybdenum sulfide, with high theoretical capacities, have been considered as one of most promising anode materials for lithium-ion batteries (LIBs). However, the poor cyclability and low rate performances originating from the large volume expansion and poor electrical conductivity extremely inhibit their practical application. Here, the electrochemical performances are effectively improved by growing amorphous cobalt sulfide and molybdenum sulfide onto amorphous carbon-coated multiwalled carbon nanotubes (CNTs@C@CoS and CNTs@C@MoS ). The CNTs@C@CoS presents a high reversible specific capacity of 1252 mAh g at 0.2 Ag , excellent rate performance of 672 mAh g (5 Ag ), and enhanced cycle life of 598 mAh g after 500 cycles at 2 Ag . For CNTs@C@MoS , it exhibits a specific capacity of 1395 mAh g , superior rate performance of 727 mAh g at 5 Ag , and long cycle stability (796 mAh g after 500 cycles at 2 Ag ). The enhanced electrochemical properties of the electrodes are probably ascribed to their amorphous nature, the combination of CNTs@C that adhered and hindered the agglomeration of CoS and MoS as well as the enhanced electronic conductivity.
