In this thesis work, Carbon based anode materials have been investigated, and we reported how microstructure changes affect the electrochemical performance when used as an anode for Lithium-Ion batteries. We have explored two hard carbon precursors: Polyvinylidene fluoride (PVDF) polymer and SU 8 (epoxy based resin). Depending upon the precursors and synthesis conditions hard carbons differ in their microstructure regarding crystallinity, porosity, morphology and also in the heteroatoms content and functional groups. To enhance the electrochemical performance we have optimized different synthesis parameters like pyrolysis temperature for PVDF and varied the aspect ratios in case of SU 8. We used different characterization techniques like Brunauer- Emmett-Teller, Transmission Electron Microscopy, Scanning Electron Microscopy, X-ray diffraction, 3D Optical Profiler and Fourier Transform Infrared Spectroscopy to determine their microstructure, crystallinity and functional groups attached. We performed Galvano static charge/discharge experiments and cyclic voltammetry to determine the electrochemical performance.
