Abstract

由于具有良好的能量和功率特性, 以及钠资源丰富和成本低, 钠离子混合电容器(SIHCs)在大规模储能应用中受到了广泛的关注. 然 而, 负极材料缓慢的动力学严重限制了SIHC器件的整体电化学性能. 本文报道了一种纳米管状硬碳(NTHC)负极材料用于制作高性能 SIHC, 这种材料是通过高温碳化(1150°C)聚苯胺(PANI)得到的. 结果显示, NTHC作为钠离子半电池负极, 在0.05 A g−1下具有高的可逆容 量(419.5 mA h g−1)和优异的倍率性能. 利用HCNT作为负极和高容量活性炭(APDC)作为正极组装的SIHC器件在2850 W kg−1的功率密度 下表现出的能量密度高达133.0 W h kg−1, 当功率密度高达14250 W kg−1条件下器件能量密度仍然保持100.9 W h kg−1; 在1.5–3.5 V的电位 范围内, 器件展现出良好的循环稳定性, 在2 A g−1条件下循环12000次后其容量保持率高达82.5%.
