The preparation of N-doped porous carbon (NC-800) is presented via facile mango stone carbonization at 800 °C. The NC-800 material exhibits good cycle stability (the capacity retention is 97.8% after 5000 cycles) and high specific capacitance of 280 F/g at 1 A/g. Furthermore, the assembled symmetric device of NC-800//NCs-800 exhibits about 31.1 Wh/kg of energy density at 800 W/kg in a voltage range of 0-1.6 V. The results of the study suggest that NC-800 may be a promising energy storage material for practical application.
通过在800℃下对芒果核进行简便的碳化处理制备了氮掺杂多孔碳（NC-800）。NC-800材料表现出良好的循环稳定性（5000次循环后容量保持率为97.8%），在1 A/g电流密度下比电容高达280 F/g。此外，NC-800//NCs-800组装的对称器件在0-1.6 V电压范围内、800 W/kg功率密度下能量密度约为31.1 Wh/kg。研究结果表明，NC-800可能是一种有前景的用于实际应用的储能材料。
