有机合成多孔碳(OSPC)是共轭微孔聚合物材料的一个子类,已显示出在离子电池中作为阳极的潜在应用。然而,一个具有挑战性的,低产量,多步合成路线(A方法)阻碍了对这一令人兴奋的家族的进一步探索。这里,OSPC-1是通过一种替代方法合成的,从市售试剂中高效的一锅法(B法),以下称为OSPC-1b,与OSPC-1a相比,通过A方法合成。表征揭示了具有909m2g-1的OSPC-1b(或OSPC类似物)家族成员迄今为止的相同聚合物结构和最高表面积。OSPC-1b作为锂离子电池的阳极进行了测试,表现出同样的高容量,快速充电,抗降解,并抑制作为OSPC-1a的危险锂枝晶的形成。此外,首次对OSPC-0的电化学性能进行了评价,与先前的预测值一致,为特定属性的设计和定位提供范围。
Organically synthesized porous carbon (OSPC) is a subclass of conjugated microporous polymer materials that have shown potential applications as anodes in ion batteries. However, a challenging, low-yielding, multistep synthetic route (the A method) has hindered further exploration of this exciting family. Here, OSPC-1 has been synthesized via an alternative, efficient one-pot method from commercially available reagents (the B method), hereafter referred to as OSPC-1b in contrast to OSPC-1a, where it is synthesized via the A method. Characterization revealed the same polymer structure and the highest surface area to date of an OSPC (or OSPC analogue) family member for OSPC-1b with 909 m2 g-1. OSPC-1b was tested as an anode for Li-ion batteries, demonstrating the same high capacity, fast charging, resistance to degradation, and inhibition of the formation of dangerous lithium dendrites as OSPC-1a. Furthermore, the electrochemical properties of OSPC-0 were evaluated for the first time, agreeing with previously predicted values, giving scope for the design and targeting of specific properties.
