The Effect of Carbon Addition on the Performance of Zn- Mn0 25Fe2 75O4 C Battery as Zinc-Ion Battery Electrode Thesis Department of Physics Faculty of Mathematics and Natural Sciences State University of Malang. Advisors (I) Prof. Dr. Sunaryono M.Si. (II) Dr. Eny Latifah M.Si. Keywords ion battery Zn-Mn0.25Fe2.75O4 C nanocomposite addition of carbon battery electrodes. As vital energy storage devices batteries come in various types each with advantages and disadvantages ranging from single-use to rechargeable batteries. They contain chemicals such as mercury lead nickel lithium and cadmium. One important type of battery is the Lithium Ion Battery (LIB) which has been the focus of extensive research. However the future of LIBs in large-scale applications is hindered by cost lifespan and safety issues. An alternative is the aqueous battery which uses water-based electrolytes. The synthesis method in this research involves the production of Mn0.25Fe2.75O4 nanoparticles from iron sand from Sine Beach which is reacted with HCl added with MnCl titrated with NH OH filtered and calcined. The Mn0.25Fe2.75O4 C nanocomposite is heated in an autoclave with ethylene glycol and sucrose. Electrodes are made from nanoparticles MWCNT carbon black and PVDF. The characterization methods used in this research include XRD to characterize the crystal structure FTIR to identify functional groups VSM to analyze magnetic properties TEM to observe morphology CD to test battery cycles and CV to assess the electrochemical performance of the battery cells. This research aims to produce new materials for Zn-Mn0.25Fe2.75O4 C battery electrodes. The results of this research include FTIR characterization showing the presence of O-H C-O Fe-O and Mn-O groups in Mn0.25Fe2.75O4 as well as C C C-N and C O groups in Mn0.25Fe2.75O4 C. XRD reveals a cubic crystal structure with particle sizes ranging from 6.10 nm to 11.53 nm. The VSM analysis shows the Ms value for each nanocomposite sample is 0.75-0.88 emu/g. TEM reveals an average particle size of 11.5 nm with evidence of magnetite nanoparticle aggregation. CV results show significant potential for Zn- Mn0.25Fe2.75O4 C as a reliable battery anode with the highest specific capacitance in MCF2. Charging-discharging tests highlight performance differences among the three samples MCF2 MCF3 and MCF4 where MCF2 is suitable for large energy storage MCF3 for fast charging and MCF4 for low-performance requirements.
