Low-Cost Production of Fe3O4/C Nanocomposite Anodes Derived from Banana Stem Waste Recycling for Sustainable Lithium-Ion Batteries

The development of lithium-ion batteries (LIBs) has become an important aspect advanced technologies. Although LIBS have already outperformed other secondary batteries, they still require improvement in various aspects. Most crucially, graphite, the commercial anode, a lower capacity than emerging materials. goal this research is to develop carbon-based materials from sustainable sources. Banana stem waste was employed as precursor because its xylem structure and large surface area. In addition, catalytic graphitization biomass yields both graphitic carbon metal oxides, which can be converted into higher-capacity Fe3O4/C nanocomposites. nanocomposites consist nanoparticles distributed on sheet. It found that not only achieved superior specific (405.6 mAh/g at 0.1 A/g), but also had good stability long-term cycling (1000 cycles). Interestingly, significantly greater graphite high current density (2 172.8 compared 63.9 mAh/g. For these reasons, simple preparation approach, with environmental friendliness low cost, produce electrochemical properties. Thus, approach may applicable varied biomasses. These newly developed derived banana recycling were suitable used anodes for LIBs.
