Abstract

With society's rapid progress, there is an increasing need for electricity among individuals, but the prevailing source of electricity is still mainly obtained through the burning of nonrenewable fossil fuels, which are not renewable and pose serious environmental hazards. Lithium-ion batteries are used widely for excellent rechargeable capabilities and high energy density. Recently, researchers have become increasingly interested in transition metal sulfides owing to their cost-effectiveness and remarkable specific capacity. However, their commercialization has been hindered by the expansion of material volume and low electrical conductivity during charging and discharging. We have successfully designed and synthesized MoS₂ nanosheets loaded on carbon spheres with a 3D hollow structure starting from SiO₂ as a template. Due to the doping of carbon materials and particular 3D hollow structures, the optimal C/MoS₂-0.3 hollow nanocomposites exhibit excellent electrochemical performance. Following exposure to over 900 cycles at a 0.5 A g^-1 ampere density, the materials exhibited an exceptional 958.50 mAh g^-1 reversible capacity, demonstrating their remarkable performance.
