| Abstract Scope |
Sodium-ion batteries (NIBs) are a promising alternative to lithium-ion batteries, but fabricating appropriate anode materials is challenging. We demonstrated fabrication of a composite anode material that uses activated carbon (AC) from readily available Date palm biomass and alpha-structured manganese dioxide (ASMD). Results showed that pyrolysis and subsequent hydrothermal treatment of the AC enabled the formation of a composite with ASMD integrated uniformly in the AC matrix. Scanning electron microscopy (SEM) showed the AC had a mesoporous structure while the ASMD had a rod-like appearance. The fabricated composite (ASMD/AC) had a uniform distribution of the ASMD, creating spaces that facilitated sodium ion diffusion. Electrochemical performance tests illustrated a specific discharge capacity of about 120 mAh/g at 50 mA/g, a coulombic efficiency of 99.7% even after 100 cycles, and good cycling stability. These results showed that the fabricated ASMD/AC is a promising material for use in the anode of NIBs. |
