Due to the demand for low-cost and safe batteries, Na-Seawater batteries (SWBs) have gotten a lot of attention as a potential energy storage device (ESS). We synthesized nanostructured and N and P dual-doped hard carbon in this study by easily carbonizing abundant biomass, pine pollen. The oxygen electrtrocatalytic performance of pine pollen carbon (PPC) for a cathode is confirmed by a seawater half-cell test, which indicates Pt/C (20 wt percent) and commercial hard carbon (HC) electrodes have the lowest overpotential. The sodium-storage efficiency of PPC as an anode active material is tested using a coin-type Na half-cell, which has a larger reversible capacity than the HC electrode. This SWB was created using both anode and cathode PPC electrodes and has an EE of 74 percent and a coulombic efficiency (CE) of 98 percent, lowering the production cost. |
