3D Structured MoSe₂ on Nitrogenous Porous Carbon Composite Anodes for High-Performance Lithium-Ion Battery

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 MoSe2 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 full-cell prototype is demonstrated by integrating the designed anode with LiNi0.6Mn0.2Co0.2O2 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.
