| Summary: | Sodium ion batteries have the potential to replace the current lithium ion batteries commonly used. Sodium ion batteries have great potential in the world, especially in Indonesia because of the large number of the elements. One of the many sodium compounds found is as salt (NaCl). Sodium batteries also have a capacity that is not less good compared to lithium ion batteries. The most potent sodium ion compound to be developed is NaFePO4. In this study, we will discuss the effect of the percentage of carbon as anode and the influence of the calcination temperature on the electrical conductivity of the NaFePO4 battery cathode. The percentages used are 0% wt, 1% wt, 2 wt%, 3 wt%, and 4 wt%. The temperature of calcination performed is temperature 600 ° C, 700 ° C, and 750 ° C. The NaFePO4 compound was synthesized using a sol-gel method with a precursor NaCl, NH4) 2HPO4, Fe (NO3) 3.9H2O then calcined to form NaFePO4 compound and its by-product. From the data obtained was the highest presentation of NaFePO4 at 600 ° C. Viewed from the structure of the nanonya, all samples can reach approximately 100 nm and made porosity. But the sample particles are still agglomerated into a large particle. |
