A metal-free porphyrin T4PP with a pyridine group is proposed as a new electrode for lithium/sodium-based dual-ion batteries (LDIBs/SDIBs). The electrochemical performance and reaction mechanism of T4PP are explored thoroughly. The extended porphyrin conjugated structure by the pyridine groups enables an excellent cycle life (5000 cycles) and a high-power density (18.7 kW kg−1). A hybrid charge-storage mechanism with the contribution of both cations and anions benefits fast charge transfer.

用于双离子电池的具有混合电荷存储的双极吡啶功能化卟啉
提出了一种带有吡啶基团的无金属卟啉 T4PP 作为锂/钠基双离子电池 (LDIBs/SDIBs) 的新电极。深入探讨了 T4PP 的电化学性能和反应机理。吡啶基团扩展的卟啉共轭结构可实现出色的循环寿命（5000 次循环）和高功率密度（18.7 kW kg -1）。阳离子和阴离子共同作用的混合电荷存储机制有利于快速电荷转移。
