The novel functionalized porphyrin [5,15-bis(ethynyl)-10,20-diphenylporphinato]copper(II) (CuDEPP) was used as electrodes for rechargeable energy-storage systems with an extraordinary combination of storage capacity, rate capability, and cycling stability. The ability of CuDEPP to serve as an electron donor or acceptor supports various energy-storage applications. Combined with a lithium negative electrode, the CuDEPP electrode exhibited a long cycle life of several thousand cycles and fast charge–discharge rates up to 53 C and a specific energy density of 345 Wh kg⁻¹ at a specific power density of 29 kW kg⁻¹. Coupled with a graphite cathode, the CuDEPP anode delivered a specific power density of 14 kW kg⁻¹. Whereas the capacity is in the range of that of ordinary lithium-ion batteries, the CuDEPP electrode has a power density in the range of that of supercapacitors, thus opening a pathway toward new organic electrodes with excellent rate capability and cyclic stability.

卟啉配合物作为高效能储能的自调节电极材料

新型功能化卟啉[5,15-双（乙炔基）-10,20-二苯基卟啉]铜（II）（CuDEPP）用作可充电能量存储系统的电极，具有出色的存储容量，速率功能和循环能力稳定。CuDEPP用作电子给体或受体的能力支持各种储能应用。与锂负极相结合，CuDEPP电极具有几千个循环和快速充电-放电速率高达的循环寿命长至53℃和345瓦时kg的比能量密度^-1在29千瓦kg的比功率密度^{- 1}。结合石墨阴极，CuDEPP阳极可提供14 kW kg ^-1的比功率密度。尽管容量在普通锂离子电池的容量范围内，但CuDEPP电极的功率密度在超级电容器的范围内，因此开辟了通向具有优异倍率性能和循环稳定性的新型有机电极的途径。
