“…The electrochemical behavior is very similar to our hybrid material even with the persistent increase in capacity, which is likely related to a change in the material and/or reaction mechanism. While slightly higher delithiation capacity is obtained after 250 cycles compared to our system, the capacities are very similar Chen et al [54] Amorphous Larson et al [56] Molybdenum oxide nanoporous asymmetric membranes ChemSusChem after 150 cycles when comparing the two systems (1 000 mAh g À 1 ). The coupled Mo 2 C@C core-shell nanocrystals on 3D graphene fabricated in the work of Xin et al [53] also show very comparable capacity values (reversible capacity of 1090 mAh g À 1 after 100 cycles at 0.1 A g À 1 ).…”

Inorganic‐organic hybrid materials with redox‐active components were prepared by an aqueous precipitation reaction of ammonium heptamolybdate (AHM) with para‐phenylenediamine (PPD). A scalable and low‐energy continuous wet chemical synthesis process, known as the microjet process, was used to prepare particles with large surface area in the submicrometer range with high purity and reproducibility on a large scale. Two different crystalline hybrid products were formed depending on the ratio of molybdate to organic ligand and pH. A ratio of para‐phenylenediamine to ammonium heptamolybdate from 1 : 1 to 5 : 1 resulted in the compound [C6H10N2]2[Mo8O26] ⋅ 6 H2O, while higher PPD ratios from 9 : 1 to 30 : 1 yielded a composition of [C6H9N2]4[NH4]2[Mo7O24] ⋅ 3 H2O. The electrochemical behavior of the two products was tested in a battery cell environment. Only the second of the two hybrid materials showed an exceptionally high capacity of 1084 mAh g−1 at 100 mA g−1 after 150 cycles. The maximum capacity was reached after an induction phase, which can be explained by a combination of a conversion reaction with lithium to Li2MoO4 and an additional in situ polymerization of PPD. The final hybrid material is a promising material for lithium‐ion battery (LIB) applications.

“…Thus, molybdenum oxides as highcapacity anodes of (LIBs) have potential applications [3][4][5]. However, due to the poor electrical conductivity of these materials, the ion diffusion is sluggish, the phase transition is irreversible, and the volume changes greatly during the process of lithium and de-lithium, leading to inferior electrochemical performance [6,7]. To overcome these shortcomings, MoO 3 and MoO 2 nanomaterials were embedded in conductive carbon matrix to fully utilize their high theoretical capacities and improve their electrochemical performance [8][9][10].…”

In this work, a new MoO3@Mo2CT x nanocomposite was prepared from two-dimensional (2D) Mo2CT x MXene by in-situ oxidization in air, which exhibited wonderful lithium-storage performance as anodes of lithium-ion batteries (LIBs). The precursor Mo2CT x was synthesized from Mo2Ga2C by selective etching of NH4F at 180 °C for 24 h. Thereafter, the Mo2CT x was oxidized in air at 450 °C for 30 min to obtain MoO3@Mo2CT x nanocomposite. In the composite, in-situ generated MoO3 nanocrystals pillar the layer structure of Mo2CT x MXene, which increases the interlayer space of Mo2CT x for Li storage and enhances the structure stability of the composite. Mo2CT x 2D sheets provide conductive substrate for MoO3 nanocrystals to enhance the Li+ accessibility. As anodes of LIBs, the final discharge specific capacity of the MoO3@Mo2CT x composite was 511.1 mAh g-1 at current density of 500 mA g-1 after 100 cycles, which is about 36.7 times that of pure Mo2CT x MXene (13.9 mAh g-1) and 3.2 times that of pure MoO3 (159.9 mAh g-1). In the composites, both Mo2CT x and MoO3 provide high lithium storage capacity and can enhance the performance of each other. Moreover, this composite can be made by a facile method of in-situ oxidation. Therefore, the MoO3@Mo2CT x MXene nanocomposite is a promising anode of LIB with high performance.
