In the realm of advanced battery technologies, 2D materials, particularly metal chalcogenides, have emerged as promising candidates due to their unique structural properties, offering superior lithium-ion storage capacity. Despite their advantages, challenges, such as volume expansion and sluggish ion diffusion kinetics, necessitate improvements through composite materials. This study focuses on addressing these issues by creating a 3D-structured anode material by integrating MoSe 2 nanosheets onto nitrogenous porous carbon dodecahedra derived from zeolitic imidazolate framework (ZIF-8). This design mitigates volume expansion and provides a shorter lithium diffusion path. The resulting composite exhibits high specific capacity, remarkable rate capability, and enduring cycling performance when employed for lithium storage, the results being superior to that reported so far in the literature for this particular electrode structure. Further, a fullcell prototype is demonstrated by integrating the designed anode with LiNi 0.6 Mn 0.2 Co 0.2 O 2 as the cathode material. This configuration exhibits a remarkable capacity retention of 70% over 200 cycles, showcasing the potential for practical applications of these electrodes in energy storage systems.

A nanocomposite of reduced graphene oxide/ MoSe 2 /nitrogen-doped carbon (RGO/MoSe 2 /NC) was obtained by the in situ conversion of a composite composed of the organic molybdenum complex MoO 2 (acetylacetone)(1,10-phenanthroline) and graphene oxide. The as-obtained nanocomposite demonstrated a distinctive structure where ultrathin MoSe 2 nanosheets were uniformly distributed in the NC matrix that firmly attached to the RGO nanosheets. The NC and RGO not only provided a synergistic framework for electron transport and Li + diffusion but also helped to expose more active sites and buffer the volume changes of MoSe 2 during the lithiation/delithiation process. Notably, a lithium-ion-based dual-ion battery configuration with the RGO/MoSe 2 /NC nanocomposite and commercial graphite respectively serving as the anode and cathode was assembled, which demonstrated remarkable cycling stability, retaining 70% (70 mA h g −1 based on cathode at 2C) of its initial capacity after 500 cycles. Moreover, it exhibited a noteworthy reversible capacity and exceptional rate capability within the high operational voltage window of 2−5 V.
