Based on multielectron conversion reactions, layered transition metal dichalcogenides are considered promising electrode materials for sodium‐ion batteries, but suffer from poor cycling performance and rate capability due to their low intrinsic conductivity and severe volume variations. Here, interlayer‐expanded MoSe2/phosphorus‐doped carbon hybrid nanospheres coated by anatase TiO2 (denoted as MoSe2/P‐C@TiO2) are prepared by a facile hydrolysis reaction, in which TiO2 coating polypyrrole‐phosphomolybdic acid is utilized as a novel precursor followed by a selenization process. Benefiting from synergistic effects of MoSe2, phosphorus‐doped carbon, and TiO2, the hybrid nanospheres manifest unprecedented cycling stability and ultrafast pseudocapacitive sodium storage capability. The MoSe2/P‐C@TiO2 delivers decent reversible capacities of 214 mAh g−1 at 5.0 A g−1 for 8000 cycles, 154 mAh g−1 at 10.0 A g−1 for 10000 cycles, and an exceptional rate capability up to 20.0 A g−1 with a capacity of ≈175 mAh g−1 in a voltage range of 0.5–3.0 V. Coupled with a Na3V2(PO4)3@C cathode, a full cell successfully confirms a reversible capacity of 242.2 mAh g−1 at 0.5 A g−1 for 100 cycles with a coulombic efficiency over 99%.

“…However, MoS 2 structure cannot be restored once it decomposes to Na x S and metallic Mo [109]. The same mechanism on deep discharge was reported for MoSe 2 [128]. It was proposed that MoSe 2 is converted to Mo and Na 2 Se in the first discharge process.…”

This review describes recent advances in electrochemical water electrolysis and rechargeable beyond Li-ion battery research, two emergent and widely employed technologies playing important roles in clean energy production and storage. The principle components of these electrochemical processes are electrode materials, which are currently facing challenges in performance improvement, thus motivating the development of novel electrode materials. This development requires synergistic interactions between experimentalists and theorists with backgrounds in solid state chemistry, condensed matter physics, and materials science and engineering. In light of a large amount of literature covering the topic, we will focus this review on the seminal electrode materials that have been discovered in the last five years, such as transition metal chalcogenides, carbides, and phosphides, as well as 2D layered materials. Intensive cross-disciplinary research is also dedicated to nanostructuring and hybridization of the emerging electrode materials in order to maximize the efficiency and simultaneously to lower the cost of the processes. As the understanding of the nanoscale-related effects deepens, it opens important pathways to the discovery of further materials and their improvement.

Exploring advanced anode materials with highly reversible capacity have gained great interests for large-scale lithium storage. A facile two-step method is developed to synthesize nitrogen-doped carbon coated MoSe microspheres via hydrothermal plus thermal polymerization. The MoSe microspheres composed of interconnected nanoflakes are homogeneously coated by a thin nitrogen-doped carbon (N-C) layer. As an anode for lithium ion batteries, the MoSe /N-C composite shows better reversibility, smaller polarization, and higher electrochemical reactivity as compared to the unmodified MoSe microspheres. The MoSe /N-C electrode delivers a high specific capacity of 698 mAh g after 100 cycles at a current density of 100 mA g and good high rate performance (471 mAh g at a high current density of 2000 mA g ). The improved electrochemical performance is attributed to the conductive N-C coating and hierarchical microsphere structure with fast ion/electron transfer characteristics.
