We report a unique N/O co-doped urchin-like carbon microspheres (UCMSs) via facile pyrolysis process based on urchin-like polyaniline microspheres (UPMSs) as precursor. UPMSs are obtained through simple self-assembled method without any aided reagent, so the total preparation process of UCMSs is very easy and repeatable. Among three samples, UCMSs-600 shows high lithium storage capacity at 50 mA g⁻¹ (952 mAh g⁻¹) and UCMSs-700 possesses relatively good rate and cycling performance (only 0.026% of attenuation in every cycle at 0.5 A g⁻¹). The correlation between structural parameters (carbon interlayer distance, ordered degree, pore structure and heteroatom doping) and lithium storage features (reversible capacity, rate and cycling performance) of UCMSs with different carbonization temperatures are discussed in detail. And we can obtain the conclusion that designing carbon materials with unique spherical structure and heteroatom-doped feature is a very efficient approach to obtain advanced lithium ion batteries.

我们报告了一种独特的N / O共掺杂的以胆红素样聚苯胺微球（UPMSs）为前体的热解过程，通过这种热解过程，共掺入了胆红素样碳微球（UCMSs）。UPMS通过简单的自组装方法获得，无需任何辅助试剂，因此UCMS的整个制备过程非常容易且可重复。其中三个样品，在50mA克UCMSs-600显示出高的锂存储容量^-1（952毫安克^-1）和UCMSs-700在0.5 A克具有在每个周期衰减的相对良好的速率和循环性能（仅0.026％^{- 1个}）。详细讨论了不同碳化温度下UCMS的结构参数（碳层间距离，有序度，孔结构和杂原子掺杂）与锂存储特征（可逆容量，速率和循环性能）之间的相关性。由此可以得出结论，设计具有独特球形结构和杂原子掺杂特征的碳材料是获得高级锂离子电池的一种非常有效的方法。
