“…Three categories of carbon materials are commonly considered for sodium-ion insertion: hard carbon, soft carbon, and graphite [10]. Among these, hard carbon exhibits the highest sodium-ion storage capacity due to its inherently random carbon bond structure, resulting in a larger gap or pore than graphite and soft carbon [11].…”

This study aimed to synthesize materials from the carbon biomass of sunflower seed husk (Helianthus annuus) for sodium ion battery anode. A simple carbonization process was carried out by roasting. The chemical activation process was conducted by adding KOH as much as 4 M in 100 mL water solution for 20 hours. Then drying was done in the oven at a temperature of 100°C for 20 hours, and then continued with the sintering process at a temperature of 900°C for 2 hours. The sintered results were washed and hydrothermal for 20 hours at 200°C with 4 mL H2O2 and 1 mL EG in 50 mL Teflon. The resulting acid degree was neutralized (pH ~ 7) with distilled water and then dried at 100°C for 20 hours. The hydrothermal powder was pulverized using a mortar and pestle and then sieved on a 325 mesh sieve. Anode sheets were prepared by mixing active ingredients : PVDF : Super-P with a composition of 85 : 10 : 5 by adding 2 mL of DMAC solvent. Electrochemical characterization testing was carried out to see the resulting performance. The results obtained from EIS, CV, and CD show that commercial hard carbon is better.
